Rocky desertification treatment project in karst areas in South China
Abstract
Rocky desertification is one of the most severe ecological problems in karst areas of South China. Severe vegetation degradation, high soil erosion, high exposed bedrock and fast groundwater flow through karst conduits are typical characteristics in the rocky desertification areas. From 2008, the rocky desertification treatment project was conducted by the Chinese government to improve the local ecological environment. This paper has offered an overview of the rocky desertification treatment project, and the partitions for the rocky desertification treatment. Changes in the spatial and temporal distribution of different severity of rocky desertification were investigated. Diverse vegetation restoration modes and ecological engineering technology modes for rocky desertification management were introduced. We also discussed the vegetation restoration effects and the carbon absorbing effects by Chinese rocky desertification treatment project. Besides, the problems exist in the rocky desertification treatment were analyzed in our study. The new rocky desertification treatment project will be carried out from 2016 in China. We need continue to summarize the past experiences, and gain more achievements from the new project.
