摘要:
 土地资源是人类社会生存和发展的最基本资源，在生态脆弱的干旱区与荒漠区，土地资源往往因经济发展而受到诸多生态环境压力。因此，对土地生态经济系统的可持续性进行研究具有重要意义。以磴口县为研究区，应用能值分析方法，结合土地利用转移矩阵、动态度等方法，系统研究2003-2015年间的土地生态经济系统可持续性情况。结果表明：1）在磴口县土地生态经济系统内，建设用地系统对土地总体能值影响最大，但建设用地系统自身处于严重的“消费型”系统，可持续性较低，面临较大环境压力。2）研究时段内，磴口县土地系统整体经历了从严重土地沙漠化至沙化被遏制的过程，该结论是从土地利用数据中分析得出，并在能值分析中得到了严密的印证。说明当地积极的沙漠化治理卓有成效。3）研究期内，磴口县土地生态经济系统总体能值投入产出比、土地可持续利用指数均在降低，土地环境负载指数逐步增大。说明研究区的可持续性在该时段内较差，并且未来的可持续性发展也并不乐观，亟需措施来遏制。
Abstract:
 Land resources are the most basic resources for the survival and development of human society.In ecologically fragile arid and desert areas,land resources are often subjected to many ecological and environmental pressures due to economic development.Therefore,it is very important to study the sustainability of land eco-economic system.In this paper,Dengkou County was chosen as the study area,and the land eco-economic system sustainability was studied systematically from 2003 to 2015 by using the energy analysis method and the methods of land use transfer matrix and dynamic degree.The results showed that 1) in Dengkou County,construction system had the greatest impact on the total energy of land in the land eco-economic system,it belonged to a serious “consumption” system with low sustainability and large environment pressure.2) The analysis of land use data and energy analysis demonstrated that in the study period,the land system of Dengkou County had experienced the process from desertification to non-desertification,indicating that the local active desertification control was fruitful.3) In the study period,the total energy input-output ratio,land sustainable utilization index were decreasing,and the land environmental load index was increasing,indicating that the sustainability of the study area was poor in this period,and the future of sustainable development is not optimistic,measures are needed to improve the situation.
