和田河流域土地生态系统服务价值变化及敏感性研究
Study on the Service Value of Land Ecosystem and Sensitivity in Hotan River Basin
摘要
Abstract
In order to explore the ecological benefits of comprehensive reclamation in Hotan river basin,the remote sensing data in 1990,2000 and 2010 were collected.Then,the Constanza value coefficient,which was conformed to the characteristics of arid region,was amended according to the practical situation of study area.At last,the change of land area and ecological service value from 1990 to 2000 were analyzed,and the sensibility of service value to fluctuating of coefficient was discussed.The results are as follows.(1) From 1990 to 2010,the changes in the area of forest was biggest,and the area of forest increased by 29.33％;the changes of the areas of grassland,cultivated land,wetland were smaller relatively,and areas of grassland,cultivated land,wetland decreased by 7.42 ％,17.45 ％,7.1 ％,respectively;what's more,the decrease ranges of river lake and desert area were all below 1％.(2) The values of ecosystem service were 38.062 billion yuan,34.182 billion yuan,35.083 billion yuan in 1990,2000,2010,respectively;the value of ecosystem service in 2000 was decreased by 7.83％ compared to that in 1990,it was decreased 7.83％ in 2010 compared to that in 1990.(3) The sensibility of estimated results to ecological service value coefficients was all under 0.35 based on the sensitivity analysis,thus the value coefficients were reasonable and the results were reliable.关键词
