Analysis on Impacts of Land Use Changes on Ecosystem Service Value in Tongchuan City
摘要
Abstract
The changes in land use structure and type would impact the appropriate changes of ecosystem service value(ESV).Based on the Constanza′s ecosystem service value theory and using the coefficients advanced by Xie Gao-di and co-works,who made a table listing the ESV of unit area in land ecosystem and providing the average unit price of ESV in China,the spatial-temporal changes of land use was analyzed and their effects on the spatial-temporal changes of ESV was examined.Also,gray Association was used to calculate the correlation between the land use type and ESV quantitatively.The following results and conclusions could be obtained.During the study period,the area of cultivated land,woodland and construction land increased,and woodland increased greatly;while grassland and unutilized land decreased sharply.There exist significant differences in land use extent.And the extent of Wangyi District was largest,while Yijun County was least.Gross ESV and the value of different kinds of ecosystem services increased.By calculating the relational degree,it indiciated that ESV of construction land and woodland played the most important role in gross ESV.关键词
