【摘要】 利用ArcGIS从安徽省2000,2005年和2010年遥感影像中提取土地利用类型数据,基于LUCC从服务强度和区位指数两个方面计算了安徽省各类土地利用类型的生态系统服务价值,并进一步分析了其时空变化。结果表明:土地类型分布上,安徽省北部平原地区(宿州、淮北等)为单一的耕地类型,南部(黄山等)和西部(六安等)为组合类型,由北到南呈现单一到多样的变化;安徽省生态系统服务价值2000~2010年期间减少了0.7%,耕地+湿地+森林的服务强度占全省的94.76%,其生态系统服务价值占全省的92.98%。安徽省各地市中,耕地、湿地和森林占的比重越大,生态系统服务价值就越大;土地利用变化是安徽省生态系统服务价值变化的主要因素。更多还原

【Abstract】 By using the data of land-use types from remote sensing images of Anhui Province in 2000,2005 and 2010 with ArcGIS,the ecosystem service values of different land types of Anhui Province are calculated from the service intensity and location index on the basis of LUCC; furthermore,the spatial and temporal changes are analyzed. The results show that on the distribution of land types,the northern plain area( Suzhou,Huaibei,etc) is single arable land; the southern( Huangshan,etc) and western area( Lu’an,etc) is a combined type,a gradual transformation from single to diversity is manifested from north to south;from 2000 to 2010,the service value of ecosystem of Anhui Province had decreased by 0.7%,the service intensity of farmland+wetland+ forests accounted for 94.76% of the whole province,and its service value of ecosystem occupied 92.98% of whole province. Among the cities of Anhui Province,the larger the portion of farm land,wetland and forests is,the greater the service value of the ecosystem is. The land-use change is a major factor to the service value variation of ecosystem of Anhui Province.更多还原
