A PRELIMINARY DISCUSSION ON THE CONNOTATION AND CONCEPTION OF SUSTAINABLE DEVELOPMENT OF AGRICULTURAL IN FRAGILE KARST ENVIRONMENT OF GUIZHOU PROVINCE

Karst landforms are widely distributed in Guizhou province where the eco-environment is very frail and there are a series of serious problems existing in agricultural sustainable development (ASD). This paper states its importance to carry out the strategy of ASD for Guizhou karst region, it also explores the target and connotations of ASD, and draws up the map of eco-environmental fragile types in Guizou karst mountainous region and points out that it is the basis for ASD of Guizhou province to protect, improve and restore karst eco-environment .
