Karst Rocky Desertification Area's Sustainable Development

The sustainable development of ecological environment fragile areas, such as concern, such as loess area, desert areas. Karst rocky desertification area is a weak ecological environment area, and rocky desertification yes district sustainable social and economic development are conditioned. Chongqing the nanchuan area as the typical in the karst area of chongqing to its sustainable development, the research has important realistic significance. Taking chongqing the nanchuan district as an example, karst environment characteristics of research and analysis, according to local existing agricultural production style, natural environment characteristics, the social economy analysis, explore on compliance with local rock characteristics of social and economic sustainable development model.Rocky desertification area relatively weak, strain capacity, the main place for people to live, need to establish a stable and harmonious and efficient environment system.
