【摘要】 基于1995、2000年的土地利用数据,应用谢高地等人制定的中国陆地生态系统单位面积服务价值表,估算了科尔沁沙地主体部分之一—赤峰市土地利用格局变化引起的生态系统服务价值的改变.结果表明,从1995~2000年5年间,赤峰市耕地增加5.04%,林地减少2.44%,草地减少1.32%,水域减少0.58%,湿地减少0.16%,城乡工矿居民用地减少0.19%,未利用地减少0.55%;研究区内土地利用变化的区域差异性很大,表现为大部分旗县仍存在毁林毁草开荒的不合理土地利用活动,尤以敖汉旗较为严重.赤峰市生态系统服务价值从1995年的782.88亿元减少到2000年的778.49亿元,净减少值为4.39亿元,减幅为0.56%;赤峰市生态系统服务价值下降主要因草地、林地转换为耕地后使得草地、林地面积减少、耕地面积增大所致.更多还原

【Abstract】 Based on the land use data of 1995 and 2000 year,and referring to the table of Chinese land ecosystem service value of unit area which was established by Xie Gao-di etc.,the effects of land use change in principal part of Horqin Sandy Land-Chifeng city on ecosystem service value were estimated.The result indicates that,from 1995 to 2000,the area of farmland increased 5.04%,the area of forestland decreased 2.44%,and one of grassland decreased 1.32%,of one water bodies decreased 0.58%,one of wetland increased 0.16%,and the land of rural-urban,industrial mining and residents reduced 0.19%,unused land decreased 0.55%.The land use in the studied area were different greatly from region to region,as most county kept abusing land by destroying forestland and grassland,especially for Aohan banner.The total ecosystem service value in Chifeng city Land decreased from 782.88×108 yuan to 778.49×108 yuan in period of 1995-2000,there was a 0.56% net decrement of 4.39×108yuan,and the decrease was caused by the decrease of grassland and forest and the increase of farmland.更多还原
