Abstract


The Karst rocky desertification threatens the living environment and sustainable development of the Karst mountain area. Desertification of agricultural land is the result of the fragile Karst agricultural system superimposes irrational human activities. Research on early warning of agricultural land rocky desertification would help us control and deal with the Karst rocky desertification problem.This research takes the Du’an Yao Autonomous County of the Guangxi Zhuang Autonomous Region as an example, using the principal components analytic method to carry on driving mechanism of agricultural land rocky desertification in Du’an and constructing early warning indexes system. Applies the Artificial Neural Networks to forecast the development of agricultural land rocky desertification in Du’an , and proposed countermeasures in agricultural optimization basing on the study. The agricultural land rocky desertification early warning theory and the method are the new point of the study.The paper includes the following four parts. The first part involves the introduction and research summarizes, elaborating research background, significance, content and method as well as the research situation in present of the Karts rocky desertification and early warning. The second part is the theory analysis of forecast agricultural land desertification. The third part predicts the development of agricultural land desertification on the basis of analyzing driving mechanism of agricultural land rocky desertification by taking the Guangxi Du’an Yao Autonomous County as the example. The fourth part comes up with the agricultural optimization regulation countermeasures and means based on the pre-warning of Du’an. The result indicated that, desertification of agricultural land in Du’an is still unoptimistic in the future, desertification governance needs to be strengthened. The humanity behavior is the key factor of the Karst rocky desertification changes. So, it is indispensable to control the humanity behavior and improvement the social environment begins.
