西安市土地利用变化及其生态系统服务价值研究
Study on Land Use Change and Its Ecosystem Service Value of Xi'an City
摘要
Abstract
According to the basic data of land use in Xi'an from 1989 to 2009,and taking 1989 as the base year,the effects of land use change on the ecosystem service value in Xi' an was analyzed.The results showed:(1) land use change of Xi'an was significant over the past 20 years,the integrated land use index fell by 7.25,farmland,water body,grassland and the unused land were shifted to construction land,woodland,garden and wetland; (2) the value of ecosystem service decreased from 1989 to 2003 (2.60)× 108 Yuan),construction land increase was the main reason,the value of ecosystem service increased by 9.74 ×108 Yuan in 2004,the value decreased from 2004 to 2009,and decreased by 3.73 × 108 Yuan.The main reason why the values of ecosystem service decreased to a considerable extent was the large scale transformation of cultivated land and forest land to construction land.The results indicate that ecosystem service value is determined by land utilization and ecosystem service value represented the degree of land utilization in Xi'an.关键词
