摘要
甘肃省庆阳市正宁县是我国农耕文化的发源地,该区既是煤炭资源集中地、辐射能源高值区,又是生态环境脆弱区,并具有重要的生态服务功能,面临着资源开发与生态环境保护的双重压力。文中运用能值理论与方法,通过建立能值指标体系,定量地评价区域的物质代谢效率与可持续发展能力,在此基础上提出物质代谢的优化措施,以促进西部县域的快速、和谐发展。
Zhengning County of Gansu Province,is abundant in coal reserves and solar energy,but ecologically fragile and has significant ecological service function,therefore facing the dual pressure of resource exploitation and environmental protection.Based on the analysis of main emergy indices of Zhengning eco-economic system during the past 20 years,we evaluated the efficiency of material metabolism and sustainable development of the study area and put forward the optimization measures to promote the fast and harmonious development of west China＇s counties.
