基于生态系统服务价值的新疆后备土地资源质量评价

Quality assessment of land reserved resources based on ecosystem service value in Xinjiang

由于人口激增、气候变暖等因素导致的环境恶化、资源短缺及其各种影响成为当今研究的重点.土地资源的有限性对人类的生存和发展产生了制约作用,更加成为研究的热点之一.为了解决土地制约的问题,必须客观地对土地资源做出评价.利用新疆土地调查资料,以新疆土地资源的利用变化图,估算生态系统服务价值(ESV),总VES为7.13×108元.其中:农田VES为0.31×108元;林地VES为1.27×108元;草地VES为3.29×108元;水体VES为1.89×108元;未利用土地VES为0.37×108元.

In recent years, due to rapid population growth, environmental degradation caused by climate warming, the shortage of resources and its effect have become key issues. Limited land resources have a function to restrain humans survival and development ,which is given more attention as lem of land restraint,we must make an objective assessment of land use and cover change （LUCC）, the dynamics of ecosystem services one of the hot spots. In order to solve the probresources. Based on the data of Xinjiang land value （ESV） caused by LUCC are evaluated. The results indicate that the total VES of Xinjiang is 7. 13 × 10^8 yuan,in which the VES of farmland is 0. 31 × 10^8 yuan,the VES of forest land is 1.27 × 10^8 yuan ,the VES of grassland is 3.29 × 10^8 yuan,the VES of water is 1.89 × 10^8 yuan,the VES of unutilized land is up to 0. 37 × 10^8 yuan,and the VES of unexploited land is one quarter of the total VES of Xinjiang. This paper provides scientific grounds for the evaluation of land use benefits and the organization of land use planning.
