【摘要】 如何协调干旱区生态环境保护与绿洲农业生态化发展之间的关系,避免绿洲系统的荒漠化,是实现绿洲人地系统可持续发展过程中亟待解决的关键问题。本文利用能值分析理论,以伊宁县为例,深入分析了温带干旱区绿洲农业生产系统的能值流动现状,厘清了伊宁县农业系统中存在的问题,进而提出了伊宁县农业生产系统的发展建议和调控措施。研究结论如下:(1)1989～2008年,伊宁县绿洲农业生态系统的能值总投入和总产出均呈持续增长趋势。(2)基于能值指标的可持续性分析表明,目前伊宁县农业生产系统仍处于可持续发展的状态,但可持续发展指数ESI呈现出波动下降的趋势;(3)在伊宁县农业生产系统今后的发展中,应保持系统中当地不可更新资源利用比率的基本稳定,使得经济反馈能值的使用比率和本地不可更新资源的使用比率同步减少,籍此提高当地可更新资源对农产品生产的贡献率,保证系统的可持续发展。更多还原

【Abstract】 how to coordinate the relationships between the protection of ecological environment and ecological development in oasis agriculture is a key spot in the Sustainable development process of Oasis agro-ecosystem. This paper used the theory of emergy,and take Yining County as an example,analyzed the emergy flow for the oasis agricultural production system in arid area,and find out the problems that existed in the agricultural system of Yining County,then proposed some suggestions and regulate measures for the agricultural production system in Yining County. The research shows that:(1) between 1989 and 2008,the emergy input and output of oasis agricultural production system in Yining County are all grows up.(2) sustainable analysis that based on the index of emergy shows that the agricultural production system of Yining County was still remain at the sustainable development stage,but sustainable development index ESI presents the tendency which the fluctuation drops;(3 ) in the future,Yining County should maintain a stable ratio for the use of renewable resource in the agricultural production system,and reduce the ratio of economical feedback emergy and nonrenewable resource,so to enhance the contribution rate of renewable resource in the agricultural production system,and guarantee the sustainable development of agricultural system.更多还原
