The Ecological Impact Assessment Of Shuiluohe Main Stream Cascade Hydroelectric Station

Shuiluohe main stream cascade hydroelectric station are located in the county of MuLi,in Sichuan,which is according to "a library ten level1" development. The ecological effect assessment is an important part of the whole project,for the project may affect the protection areas and the areas that are the source of the water.To fulfill the construction of the Shuiluohe main stream cascade hydroelectric station,some temporary constructions,such as roads, sediment ground, material ground and working places.Thus, this project has efects on this area. It will first afect the local ecological system through its effects on the plants,soil and the formation of the soil usage and its later effects on the eclogical integrality of the natural ecological system. And then,he project will flood some forest and bring on the loss of some water and soil and the loss of the living places of the wild plants and animals.Based on the history materials and the field investigation,the description and assessment was made,of the current situation of the natural environment,the land ecological system,the landscape ecology and sensitive ecological problems of this area.Many methods were used ding the landscape ecology assessment,ecology mapping and bio-production assessment.All this is based on the ecological theory.And also,the possible side effects on the ecological environment of this project were predicted and some protection measure was put forward according to the feature of the project and the ecological environment of this area. Some basic investigation data were provided for the environment protection of this area and the possible efects on the local ecology was predicted. All the work provides the operational advice for the configuration of the construction,the choice of substitutive measures and the later ecological recovery.The research shows that:1. evaluation area of change.the landscape pattern have corresponding change,will impact assessment results.2.high biodiversity exists in the affected area and the plant diversity is much higher than animal diversity.The bird diversity is the highest and the mammal diversity is lower than that.3.the ecological environment is good and this project will not result in the unrecoverable efects if the project is in strict control.4, the construction of the hydroelectric power will interfere the various parts of the ecosystem to some extent. So,the administration and the supervision must be strict and the ecologyrecovery must be carried on.
