黄土高原地区的可持续发展问题

The sustainable development in the loess platuea region

通过对黄土高原地区生态经济系统的结构、功能、特点及生态环境恶化原因的分析 ,指出生态系统的脆弱性、经济系统结构的不合理性和人口的过快增长是该区生态破坏和贫穷落后的主要原因 ,也是该区实施可持续发展战略的主要障碍。因此 ,必须从改善区域生态环境的总目标出发 ,尤其是从防治黄河下游水患的需要出发 ,通过政策调控 ,将生态环境的恢复与重建放在首位 ,建立黄河流域的生态支持体系。在此基础上合理开发利用资源 ,促进经济、社会的全面发展是实现中国黄土高原区域可持续发展的惟一正确途径。

The weakness of ecosystem, un retionalization of economic system structure and too rapid growth of population are the main causes of ecological destruction, poverty and undevelopment in this region.They are also the main obstacles of carrying out the strategy of sustainable development. Based on this point the analysis is made on the structure, function and characteristic of ecological economic systems,and the causes of ecological environment deterioration in the loess plateau region. Therefore, the restoration and reconstruction of ecological environment must be put in the first place, and the ecological suporting system of the Yellow river watersheld must be set up from the major objective of improving regional ecoenvironment, especially from the prevention and cure of the flood in the lower reaches of the Yellow river. And then the rationaly developing and using resources,improving overall development of economy and society are the only way of realizing the sustainable development of the loess plateau region of China.
