经济的快速发展和人口的急剧增加,给本就有限的土地资源带来巨大的压力,迫切需要新的理论和方法来研究土地生态经济系统,为未来土地利用结构优化和合理配置以满足人口、资源、环境协调发展提供科学的理论依据。该文以新疆阿克苏市为例,应用能值理论的方法对阿克苏市2005-2010年土地生态经济系统的能值贡献率、净能值产出率、环境承载力、环境负载率、系统优势度、系统稳定度、可持续发展指数等指标进行定量及变化趋势分析。分析阿克苏市土地生态经济系统发展状况的程度和特征,为阿克苏市土地资源的合理利用及结构的合理配置,提供可持续发展的策略和建议。

The rapid development of economy and the rapid increase of population, this is limited to the land resources to bring the huge pressure, the urgent need to new theory and method to study the land ecological economic system, for the fu- ture land use structure optimization and the reasonable configuration to meet the city population, resources and environment harmonious development to provide scientific theory. In this paper Akesu city in xinjiang as an example, the application of the theory of value method to analyze the Akesu city 2005 - 2010 land ecological economic system of values, net contribution to value output, environmental bearing capacity, the environment load rate, system dominance index, the system stability and sustainable development indices and trend of quantitative analysis. Analysis Akesu city land ecological economic system development status of degree and characteristics, Akesu city for rational utilization of land resources and rational structure configuration, provide sustainable development strategies and Suggestions.
