荒漠化由沙漠化、水土流失和盐渍化三个部分组成,它作为极其重要的环境和社会经济问题困扰着当今世界,威胁着人类的生存和发展。我国是世界上受荒漠化影响最严重的国家之一。文章从生态经济学理论探讨了干旱沙化生态脆弱区生态经济发展模式问题。以生态经济理论和实践的区域化为主线,以区域生态经济系统为主要研究客体,依据生态学进行气候干旱、水资源短缺、人口压力研究。同时结合陕西榆林市神木县实际,对该县生态经济可持续发展的模式做了实证分析,旨在促进中国区域生态经济学走向成熟,为典型生态脆弱区的可持续发展提供理论支持。
Desertification consists of three parts: desertification, soil erosion and salinization. As an extremely important environmental and socio-economic problem, it plagues the world today and threatens the survival and development of mankind. My country is one of the most affected countries in the world by desertification. The article discusses the eco-economic development model of the ecological fragile zone in arid desertification from the ecological economics theory. Taking the regionalization of ecological economy theory and practice as the main line, taking the regional eco-economic system as the main research object, the study of climate arid, water shortage and population pressure based on ecology. At the same time, combining with the actual situation of Shenmu County, Yulin City, Shaanxi Province, this paper makes an empirical analysis of the mode of sustainable development of ecological economy in this county, aiming to promote the maturity of regional ecological economics in China and provide theoretical support for the sustainable development of typical ecologically fragile regions.
