Study On The Suitability Evaluation And Model Of Eco-agricultural In The Peak-cluster Depression Of Karst Area In Guangxi Province

Karst peak-cluster depression which is of the most complex terrainand the most serious rocky desertification has become one of the mostpressing area in social economic development，which is because of its widedistribution area, special landform structure and other reasons.So，It is themajor task that need solve urgently at this stage to learn managementexperience to construct and promote the effective management pattern inorder to realize the development of karst peak-cluster depression area insociety and economy sustainable.In the specific management practice,ecological agriculture is of a comprehensive, diversity, sustainable,andefficient characteristic has become the objective and inevitable choice ofecological restoration and the rural economy and the sustainabledevelopment of agriculture in this area.Based on this background, this paper explores the Guangxi karstpeak-cluster depression development model of ecological agricultureconstruction, suitability evaluation and demonstration and extension. I hopeit can provide some reference for ecological restoration, economicdevelopment and social progress.In this paper, the authors constructed three types of peak clusterdepression，which is based on the perspective of spatial database. At thesame time，districting the area according to the similarity partition； constructing ecological agriculture development evaluation index system inthese depression areas；letting the county be the basic unit of evaluation tofuzzy clustering analysis and comparative analysis,and it is formed in foursuitability partition of ecological agriculture development in Guangxipeak-cluster depression area. At the same time，Combine with the practicalexperience for many years of comprehensive demonstration zone inGuangxi karst mountain areas to construct an ecological agriculture modefor the development of peak-cluster depression， in order to providereference and basis in theory and practice.The ecological restoration in the mode of ecological agriculture inGuangxi peak-cluster depression area, environmental governance is thepremise, the development of economic and social progress is the core,economic investment in science and technology is the means, and sciencepopularization is the key，and adhering to the concept of development inthe specific implementation to make it better and better.
