Study on RS-and GIS-based ecological capital assessment in arid areas

生态的大写的评价当前是生态学，资源经济，环境经济和生态的经济的学科交差的领域里的重要研究内容之一。为了科学地估计生态的资本，增加到决策人在经济开发考虑生态的费用，并且为在干旱区域的持续经济开发也是必要的。基于风景生态学的理论，在这篇论文生态的资本在干旱区域珍视的per 单位区域被使用 Landsat TM 数据， CBERS 卫星数据，气象学的数据， MODIS 卫星数据和另外的生态的数据研究，并且 RS --并且在干旱区域估计生态的大写的价值的官方补给底的模型被开发。而且基于测量地的数据，在在威信河盆的生态的大写的评价以后的案例研究，在 2003 的 Xinjiang 被执行。盆被划分成 4 个生态的大写的区域以便份量上计算生态系统的生态的大写的价值，分析生态的资本的空间分发，并且制定生态的资本的空间分发的地图。结果证明在在 2003 的威信河盆的生态系统的全部的生态的大写的价值是 1.494 54 癮 吗？？

Ecological capital assessment is currently one of the important research contents in the interdisciplinary field of ecology, resources economics, environmental economics and ecological economics. To scientifically assess ecological capital redounds to decision-makers to consider the ecological cost in economic development, and is also necessary for sustainable economic development in arid areas. Based on the theory of landscape ecology in this paper the per unit area ecological capital values in arid areas are researched by using the Landsat TM data, CBERS satellite data, meteorological data, MODIS satellite data and other ecological data, and the RS- and GIS-based models of assessing ecological capital values in arid areas are developed. Moreover, based on the field-measured data, a case study on ecological capital assessment in the Manas River basin, Xinjiang in 2003 is carried out. The basin is divided into 4 ecological capital areas so as to quantitatively calculate the ecological capital values of the ecosystems, analyze the spatial distribution of ecological capital, and chart the maps of spatial distribution of ecological capital. The results show that the total ecological capital value of the ecosystems in the Manas River basin in 2003 was 1.49454×10^11 yuan RMB. 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 distribution of vegetation zonality in this arid area. The assessed results can objectively reflect the ecological capital and its spatial distribution in the aridbasin, and can also provide reference for roundly carrying out the assessment of ecological capital in arid areas.
