Study on Agricultural Sustainable Development in Guizhou Karst Mountain Region Under Fragile Ecology Restriction

Guizhou province is located in the southwest of China where the karst landforms are widely distributed but its eco-enviroment is fragile.Most Guizhou area is occupied by mountains and hills where the soil ersion is very serious,and the natural conditions of agriculture produce is adverse,therefore the level and efficiency of agriculture produce is also very low.The only way of agriculture development in Guizhou Karst mountain region is to carry out sustainable development strategy.Whereas fragile eco-enviroment is restricting the agricultural sustainable development in the region.The paper analysed The cause of the fragility in Guizhou Karst mountain region was analyzed and the effect of fragile eco-enviromental restriction on the region was as follows:land using,water resource and nature disaster.etc.Finally,the corresponding countermeasures were suggested.
