Preliminary Study about the Ecological Security Problem of the Soil Erosion Area in China

摘要

The main ecological disaster in the soil erosion area in china is flood disaster, reduction in arable land, land degradation, water resource shortage and pollution, biodiversity decrease and so on. The main countermeasures are as follows: Firstly, developing the restoration capability of ecology and speeding up the comprehensive management of water and soil conservation. Secondly, controling soil erosion by law. Lastly, establish a scientific and reasonable soil erosion and ecological compensation legal system. In this paper we established a three-level and three security ecological security evaluation system that contains 15 indicators about soil erosion. We established the necessary ecological security early warning and protection system based on the evaluation system in soil erosion area.
