内蒙古鄂托克旗生态经济系统能值分析

Emergy Analysis of Ecological-economic System in Etuoke Banner of Inner Mongolia

应用能值理论计算并分析了内蒙古鄂托克旗1997～2007年生态经济系统的多项能值指标。结果表明，鄂托克旗的环境负载率、能值-货币比和能值使用密度远高于合理水平，且可持续发展指数小于1，而经济却保持高速增长，说明鄂托克旗的经济发展是以资源的大量消耗为代价的，其经济发展方式和能源利用方式亟需改进。

Emergy Theory was adopted to calculate and analyze various emergy indices of ecological-economic system in Etuoke Banner of Inner Mongolia from 1997 to 2007. Results showed that environment carrying rate, the ratio of emergy to currency and emergy density of Etuoke Banner were higher than the rational level and its sustainable development index was lower than 1 while the economy has maintained a high growth rate, which indicated that the economy of Etuoke Banner developed at the cost of large amounts of resources consumption. The economic development mode and energy utilization mode should be improved as soon as possible.
