Quantitative assessment and analysis on the dynamic change of ecological capital in arid areas

生态的资本是生物资源的直接价值和生态系统的生态的服务功能价值的求和。在 RS ， GPS 和 GIS 的支持下面，在这篇论文，估计生态的资本的 基于RS 的量的测量模型每由包括 Landsat TM 数据使用生态的参数统一区域基于生态的资本的价值上的传统的生态学理论和研究被开发， CBERS 卫星数据，气象学的数据， MODIS 卫星数据，陆地封面数据和测量地的数据。在在 1990， 1995 和 2003 的 Changji Hui 自治的府的生态的资本的空间与时间的分发上的案例研究被执行，并且在府的生态的资本的动态变化被测量并且与 GDP 相比。在学习区域的生态的资本的空间分发的地图被制定，并且生态的资本的空间分发的特征被分析。结果证明在在 1990， 1995 和 2003 的府的生态的资本的价值是 1.473 68 吗？？

Ecological capital is the summation of the direct value of biological resources and the ecological service function value of ecosystems. Under the support of RS, GPS and GIS, in this paper the RS-based quantitative measurement model of assessing ecological capital is developed based on the traditional ecology theory and the research on the value of ecological capital per unit area by using the ecological parameters including Landsat TM data, CBERS satellite data, meteorological data, MODIS satellite data, land cover data and field-measured data. A case study on the spatiotemporal distribution of ecological capital in Changji Hui Autonomous Prefecture in 1990, 1995 and 2003 is carried out, and the dynamic change of ecological capital in the prefecture is measured and compared with GDP. The maps of the spatial distribution of ecological capital in the study area are charted, and the characteristics of spatial distribution of ecological capital are analyzed. The results show that the values of ecological capital in the prefecture in 1990, 1995 and 2003 were 1.47368×10^11, 1.66160×10^11 and 1.77895×10^11 yuan RMB （hereafter referred to as yuan） respectively, and that in spatial distribution, the ecological capital decreases from the alpine zones to the plains and from the oases to the deserts, which accords with the zonal distribution of vegetation in arid areas. The measured results can more objectively reflect the ecological capital and its spatial distribution in arid areas, provide an ideal foundation for further study in the future, and can also be combined with the study on service functions of ecosystems and the regiona planning as an important basis of regional planning.
