For the details of its geography situation please see Fig. 1-1. This project is a Navigation Junction Complex constructing project. It included navigation lock, discharging sluice, power station, project of protective revetment, a little dredging works in downstream (The length of excavation section is 1630 km that will produce 25790m3 of dredging load; three new spurs will be built along the downstream.), temporary projects, living area, etc. Investment of project: The investment is estimated at RMB 267,078,000.00. 1. Goal of environmental protection 1.1 Goal of environmental protection in construction period 1.1.1 Water environment During the cofferdam constructing, dam constructing, the upstream and downstream cofferdams removing, and the excavation of both shipping way and foundation pit within cofferdam, the SS may be discharged into the water and cause water body pollution. The mail goal of water quality protection is Xiniu Town waterworks. 1.1.2 Ecological environment The construction times will about three years from 2003 to 2005. The normal hydrology condition and the living condition of aquatic will be interfered due to the construction of the project; the vegetation be damaged and land erosion become serious. Although the perturbation caused by construction of the project is unavoidable, but we can take some measure to protect the surrounding. The main objective for ecological environment is fishery resources in river, water and soil erosion and vegetation recovery.  1.1.3 Traffic order The navigation construction may influence the local traffic order. The chiefly reason is that the amount of vehicle using for transporting construction material will increase in construction period. At the moment, the objective is the safety of local people. 1.1.4 Acoustic environment and atmosphere environment The equipment, such as concrete mixer, etc. are the main noise pollution sources in construction time, some of them belong to the strong noise pollution sources. Earth and stone excavation, pilling and transport the building material, etc. will cause dust in the construction period of the project. The dust should be so controlled that the regional air quality can reach the class 2 standard of quality standard for environmental air. Main objective for acoustic and atmosphere environment is residential area both along the river and the transport road. The protection goal shown in table 1-1 and shown in Fig. 3.3, Fig. 3.4.

"Environmental Quality Standard for Surface Water" (GB 3838-2002) is the environmental quality standards for surface water assessment. Besides. the following standards are as references: 1) Water Ouality Standard for Fisheries (GBI 1607-89). The stipulations for SS in the standard says "increased SS concentration in the water by any activity is no more than 0m/L". "no harmful impacts should be allowed on any fish, shrimp or shellfish, if suspended solid set down to the bed": 2) Hygiene Standard for Drinking Water (GB5479-85): and 3) Standard for Irrigation water Quality (GB5084-92).

The buildings from the left to right one by one are navigation lock, separation zone, of power station. 11 holes 8.0 meters in width flood diversion sluice, 21 holes 8.0 meters in width flap down gate, with its right shore get in touch with the dam. The panoramic view of the Complex is shown in Fig. 1.2. The Layout of the Complex is shown in Fig. 1.3. The vertical and cross-sectional designs of the complex are illustrated in Fig. 1.4.1 .5,1.6.
