The Discussion of Plan about Water Conservation and Afforestation of Xiaanxi Artificial Aggregate Production System in Three Gorges Project

摘要

The Xiaanxi artificial aggregate production system in Three Gorges Project is the largest one in the world by now. In the process of quarrying, the problems of serious water & soil erosion and primary ecological system injury causing by excavation and dreg have not been solved. This paper analyses the site condition of the region, and basing on it, discusses the plan of water conservation and afforestation on quarry slope, stockyard platform and tailing-dump slope. Synthetically applying different methods and technologies, it would be able to achieve the efforts of conserving water and soil as well as good ecological landscape.
