【摘要】 因重要的生态屏障功能和生态系统的脆弱性,中国北方农牧交错区可持续发展是一个重要科学问题。以典型北方农牧交错区——宁夏盐池县为例,借鉴"可持续性晴雨表"理论和方法,采用熵值法确定指标权重,对盐池县的可持续发展进行定量评价,并对影响可持续发展的因素进行了分析。结果表明:(1) 1990—2015年盐池县区域发展成就显著,人类福利指数保持持续增长的趋势,但生态系统福利指数稳定增长则始于2005年禁牧等生态政策的生态效益显现以后。(2)改善教育等公共服务水平、优化产业结构可以进一步提高人类福利,经济发展可以直接改善人类福利,经济发展的成果也可以通过生态政策加大对生态环境的投入从而改善生态系统福利。在此基础上提出了盐池县可持续发展的建议。更多还原

【Abstract】 Sustainable development of the agro-pastoral transitional zone in northern China is an important scientific problem for its important ecological barrier function and the vulnerability of the ecosystem. In this paper,Yanchi,Ningxia was taken as a typical case area of agro-pastoral transitional zone in North China. We Use the theory and method of"barometer of sustainable"to assess sustainable development of Yanchi County,and the entropy method was used to determine the index weight,then the factors that affect the sustainable development were analyzed. The results showed that:( 1) The achievements of regional development in Yanchi were remarkable and the human welfare index continued growing in the 1990—2015,but the ecological welfare index did not stably row until 2005 when the ecological benefits of grazing ecological policy displayed.( 2) The improvement of the level of public services such as medical and education and the optimization of the industrial structure could further improve the welfare of human beings,moreover economic development could directly improve the welfare of human beings,and the results of development could also increase the investment in the ecological environment through ecological policies.Suggestions for sustainable development of Yanchi County were put forward.更多还原
