Abstract

运用RS和GIS技术对成都市主城区2000—2010年土地利用变化进行了分析,结果表明:①主城区土地利用类型的变化主要是城市绿地与耕地和建设用地之间的相互转化,城市绿地转为建设用地的面积为6 850hm2、占2000年城市绿地面积的41.47%,耕地转为建设用地的面积为5 323hm2、占其面积的31.01%;②主城区土地利用变化速度较快,综合土地利用动态度指数达2.74%;单一土地利用类型动态度中以交通用地变化速度最大、年变化率达13.45%,其次是建设用地和耕地、年变化率分别为9.68%和-5.10%;③主城区土地利用程度呈现增强趋势,其总体变化值为0.134。这说明在主城区
土地利用变化中,交通用地和建设用地的变化速度在整个城区的扩张中起到了决定性的作用,且随着经济的快速发展和城市化进程的加快,主城区土地利用集约度会进一步提高。

A systematic analysis is made of land use change in the main urban areas of Chengdu in the period of 2000to 2010applying RS and GIS techniques.The results show that:(1)The conversion of land use types is mainly between urban greenland,crop land and construction land.41.47% of the total area of the urban green land in 2000has been turned intoconstruction land,which increased an area of 6 850hm2;31.01% of the total area of crop land in 2000has been turned intoconstruction land,increasing an area of 5 323hm2.(2)The rate of land use change has speeded up dramatically,with thedynamic degree index of comprehensive land use amounting to 2.74%.As for the land use dynamic degree of single land useclass,the maximum rate of change is transportation land,of which the annual change rate is 13.45%.While the annual changerate of construction land and crop land is respectively 9.68%and-5.10%.(3)The land use degree of the main urban areastakes on an increasing trend,the overall change value being 0.134.The rate of transportation land and construction land changeplayed a decisive role in the expansion of the main urban areas.With the rapid economic development and the speeding up ofurbanization process,land use intensity of the main urban areas will be further enhanced.
