During the selection of railway location, in accordance with the technical standard of the Project, firstly we concentrate on the minimization of the effect on Zhujiangyuan Nature Reserve and the vegetation, protection for the Deleted: the ecological environment along the line, prevention of water loss and soil erosion, Deleted: the satisfaction with the floodwater discharge requirement of the rivers, harmony Deleted: the with the planning of the cities along the line, avoidance and minimization of the disturbance on and division of the existing towns, and the final proposal is Deleted: recommended made based on the premise of minimum impact on the environment and the Deleted: effect social economy. 1Selection of proposals for railway line in Zhujiangyuan Nature Reserve Zhujiangyuan Nature Reserve is one of the most important protection targets of the Project. The design institute and the assessment department fully study Deleted: unit and assess the sections on both sides of the existing railway that are established as the natural reserve, and finally they put forward the proposal of constructing Deleted: recommend the Additional Second Line along the existing railway. By coordination among various parties and after the consents of the related competent authorities are Deleted: A obtained, the land for Liu-Zhan Railway Line is reserved in the Natural Deleted: planned to be reserved Reserve planning, in principle, the land for Liu-Zhan Railway Line is not incorporated into the buffer zone of the Natural Reserve, the impact of the railway construction on the Natural Reserve can be minimized through 9 THE SECOND SURVEY & DESIGN INSTITUTE  Environmental Management Program for Additional Second Line Project for Liupanshui-Zhanyi Section on Guiyang-Kunming Railway multi-party coordination. At present, review of the planning draft of the Natural Reserve submitting for approval has passed by experts, and the Deleted: of the Natural Reserve planning will be readjusted in the draft for approval, and the land for the Deleted: the review Additional Second Line for Lipanshui-Zhanyi Section will be reserved. Deleted: and 2Comparison among selection of proposals for railway line at partial sections Deleted: to be constructed plus detouring The lines currently selected are basically along the existing railway, the proposal for the double detouring line is adopted at Meihuashan ~ Qiewu Deleted: due to Section in consideration of complicated geologic conditions; after comparison. Deleted: , The economical and rational speed limit proposal for Xuanwei Station that exerts Deleted: t less impact on the city and enables the full utilization of the equipment of the existing station is selected for the section at urban vicinity of Xuanwei City. Deleted: little influence Because the standard for the existing railway at Qiewu~ Zhanyi Section is Deleted: ; comparatively low, the existing radius of curve is relatively small, and both sides Deleted: b of the existing railway are incorporated into Zhujiangyuan Nature Reserve. The reconstructed section with small-radius of the Additional Second Line will Deleted: , partially cross the buffer zone and the experimental area of the Natural Reserve> Deleted: t With regard to the proposals for the railway lines at Xiaojijie~Zhujiangyuan Deleted: reconstruction section and Yanfang~Heilaowan Section that cross the Natural Reserve, the Deleted: , proposals for long, medium and short Gele tunnels are put forward. The partial cut-off proposal and the cut-off proposal for the railway line along the existing Deleted: w line are compared and selected respectively. Finally Medium Gele Tunnel Deleted: , Proposal for the railway line at Xiaojijie~Zhujiangyuan which exerts little impact Deleted: t on the Natural Reserve and the partial cut-off proposal for the railway line at Yanfang~Heilaowan along the existing line are selected. Deleted: , The railway lines currently selected exerts little adverse impact on the Deleted: f natural ecological environment , impose little disturbance and obstruction on the Deleted: influence existing towns, with obvious function of driving the economic development, Deleted: influence and it complies with the comprehensive planning and the principle of the combination of "the social benefit, economic befit and the environmental Deleted: in terms of the strike benefit", thus the proposals for the railway lines are reasonable. Deleted: have 2.2 Conclusion of the present environmental status assessment Deleted: y 1The assessed area is the human ecological system centered on the human activities and based on the agricultural production. The development history of Deleted: situation the region is long, the land use rate is comparatively high, the grain output is Deleted: gain 10 THE SECOND SURVEY & DESIGN INSTITUTE  Environmental Management Program for Additional Second Line Project for Liupanshui-Zhanyi Section on Guiyang-Kunming Railway relatively low, the vegetation coverage in Guizhou Province is poor, almost no Deleted: nearly natural vegetation exists, no rare vegetation, old and precious trees and wild rare animals requiring special protection are found, the existing animals and plants are mainly the species preserved and developed for meeting the human needs under the human control, thus the biological species are comparatively single. The ecological system covered by the assessment has relative stability and functional completeness, with certain anti-interference capability. Deleted: as well as 2The acoustic environment of the Project is mainly subject to the influence by the existing railway, the roads along the line, and the social life. The area with a distance less than 60m away from both sides of the existing railway is principally subject to the influence by the engine whistle and the running noise of training, and it exceeds the standards for the acoustic environment at different degrees. The area with a distance more than 60m away from both sides of the Deleted: greater existing railway and the areas with single detouring or double detouring track are principally subject to the influence by the road and the human social activities, and the current quality of the acoustic environment is good. 3 Most rivers crossed by the Project including Shuicheng River, Nanpanjiang River and their tributary rivers which belongs to seasonal and ephemeral streams, and the annual change in the volume of streamflow is comparatively big. The rate of the water quality of Shuicheng River up to standards is 25%, two sections Jingkou and Jiudongqiao at the middle reach belong to Class III water functional zone, the water at the two sections exceeds the standards and belongs to Class IV water and Class V poor quality water; Fangjiazhai Section at the lower reach belongs to Class V water functional zone, and the water belongs to Class V poor quality water. The water from the source region of Nanpanjiang River to the entrance of Huashan Reservoir is up to Class I water, and the water quality is "good", the water at Tianshengba Section belongs to Class V water and medium-polluted water, the water at Sheliqiao Section belongs to Class V poor quality water and heavy-polluted water. The pollutants are mainly ammonia nitrogen, COD, sulfide, SS and so on. 4The quality of the air environment of Liupanshui City reaches Class II Standard of Ambient Air Quality Standard GB3095-1996, among which, the annual average concentration of NO2 reaches Class I Standard, and the primary Deleted: volume pollutant is total suspended particleTSP. The annual average concentration of TSP in ambient air in urban area of Xuanwei City exceeds Class II Standard, the 11 THE SECOND SURVEY & DESIGN INSTITUTE  Environmental Management Program for Additional Second Line Project for Liupanshui-Zhanyi Section on Guiyang-Kunming Railway annual average concentration of SO2NO2 is up to the standard, the air pollution is mainly caused by TSP and SO2, especially TSP. 2.3 Conclusion of environmental impact assessment 1Major environmental impact in construction period 1In the course of the railway construction, water loss and soil erosion may occur after the damage to and disturbance with the native ground vegetation Deleted: interference and the soil. The areas in which soil erosion may occur include sections with deep-excavation and high-filling , borrow pit, spoil site, temporary construction Deleted: sections site, sections with special geology and other sections interfering with the ground soil layer. The soil erosion may occur due to the failure of the complete recovery of the vegetation in the first 1~2 years' operation. 2The noise occurring in the construction period is mainly caused by the construction machinery, the result of the prediction using the attenuation mode of noise synergistic effect l shows the noise at the area with a distance greater Deleted: superimposed than 60m away from the construction site by day and 120m away from the Deleted: attenuation mode construction site by night can reach the national standard. Therefore, the noise will exerts obvious effect on the residents with a distance less than 60m from the Deleted: to be constructed construction site by day and with a distance less than 120m from the construction Deleted: immersed section site by night. Deleted: of the 3The construction of the canal-crossing bridge may influence the quality of the surface water. The influences mainly include the leakage of oil and Deleted: bridge its entry into water, suspension of the bed mud and the loss of the discarded Deleted: buildings construction waste or building materials caused by the underwater works for Deleted: the lower part bridge construction , and the construction mud at the construction site and the domestic wastewater at the camp . The pollution will influence down stream of Deleted: the lower part the bridge site or of the construction yard near river, and the pollution may Deleted: underwater last in the construction period and after the completion of the construction. Deleted: export 4The major air pollution in the construction period is the construction Deleted: former dust, and the dust mainly comes from the uncompleted subgrade, the stock yard and the transportation road. Many factors may result in dust, including climatic Deleted: the conditions and the type of construction activities, the dust formation are Deleted: area with principally depend on the wind direction, wind speed, and air humidity. The Deleted: a impacted area can reach a distance of 150~200m from the construction site and both sides of the road. Deleted: entry 5The health risk is mainly the risk of transmission and diffusion of Deleted: 12 THE SECOND SURVEY & DESIGN INSTITUTE  Environmental Management Program for Additional Second Line Project for Liupanshui-Zhanyi Section on Guiyang-Kunming Railway communicable diseases in the Project area that may be caused by the increase of Deleted: in the large number of the transient population in the construction period. 6The safety problem is principally associated with the injury caused by the linear railway construction to the local residents , in particular, to children Deleted: ts who is short of safety consciousness due to the lack of isolation and control measures for the construction site. The blasting of the section and tunnel to be deeply cut may produce popping rock, and the blasting itself is a kind of potential safety hazard for residents at the vicinity of the construction site. 7Only the project activity of requisition of land and dweller removal in Deleted: engineering the construction period has permanent influence on the environment, and other Deleted: demolition activities will cause temporary influence to it. 2Major environmental impact in the operation period 1Impact on ecological environment After strict comparison, selection and reasoning , the proposal for the Deleted: demonstration Additional Second Line along the existing line is selected, the Additional Second Line will increase little impact of division of the ecological system because Deleted: division of the frequent human development activities along the line and the long-term Deleted: on operation of the existing railway. There is no rare plant and old and precious trees under the State protection in the land for the Project, the areas along the line are principally manmade forest and secondary forest, 176,900 trees will be cut for the implementation of Deleted: growth the Project, most of the trees are sparsely distributed tress, and cutting of them Deleted: the will not influence the woodland resources of the area. 1358.98 hm2 land is requisitioned for the Project, paddy field and dry land account for over 50% of the total area requisitioned for the Project, station and yard and subgrade of the railway and other production establishments will replace the semi-natural ecosystem dominated by the agricultural production, Deleted: s and former function of the land will partially or whole lose, which will cause Deleted: led certain impact on the local agriculture and cultivating fishery. The volume of earth-rock work for the line is comparatively large and reaches 2084.37
