| 摘 要： | 为更深入了解中国西部12个省、市、自治区农业生态系统的网络运行效率和发展潜力的空间差异,正确评价区域内农业生态系统对太阳能资源的利用现状与其可持续发展情况,利用能值分析方法对该区域农业生态系统的能值投入产出情况、环境承载情况和生态系统运行情况做了定量分析,结合GIS,对区域内各省、市、自治区农业生态系统综合发展水平进行等级划分和空间差异分析.结果表明:西藏、青海和新疆是最具发展潜力的地区,其可持续发展性能(EIS)大于3.0;四川、重庆、云南、广西和甘肃,环境负载较高,发展潜力较差,EIS均小于0.5;内蒙古、宁夏、陕西和贵州则处于中间地带,EIS介于0.5和3.0之间.

| Abstract: | In order to understand the spatial difference in the operating efficiency of regional interior ecosystem networks of 12 provinces in the western region of China and their development potential and to better evaluate the agricultural utilization of solar energy resources and the sustainable development of agriculture,EMA(emergy analysis) was used to quantitatively analyze the emergy input/output ratio,environment carrying capacity and the operation of the eco-system of the provinces.Grading and spatial diffe... |
