摘要:
以位于水蚀风蚀交错带的六道沟流域为研究区,应用遥感和GIS相结合的方法,提取不同年份的土地利用信息进行动态分析,并且计算了六道沟的退耕影响系数.结果表明:与1990年相比,2002年水浇地、林地类、草地类面积分别增加了43.45%、28.43%、5.83%,坡旱地减少了60.81%,土地利用结构不断优化.土地利用转换主要以耕地、林地、草地和工矿用地为主,“八五”期间土地利用变化受退耕还林影响的程度大于1995年后的影响.科技试点研究促进了当地的土地利用结构调整,1995年后采煤业的兴起,则进一步促进了土地利用结构的优化.
Abstract:
Taking Liudaogou watershed in water-wind erosion crisscross region as the study site,based on the monochrome aerial photo,the color aerial photo and the local surveying,the paper draws information on land use in different years from them by the integration of RS and GIS to analyze the dynamic changes of land use,and calculates the de-farming influencing coefficient in Liudaogou watershed from 1990 to 2002.The results showed that compared with the identical land use in 1990,the irrigable land increased by 43.45%,forestry land by 28.43% and grass land by 5.83%,while slope dry farmland decreased by 60.81% in 2002.The land use structure has been optimized gradually.During two different period from 1990 to 2002,the land use conversion has mostly happened among farmland,forestry land,grass land and mine land.The change of land use suffer more influence from the project of converting slope farmland into forestry land and grass land in the Eighth Five-year Program than after 1995;the pilot study of the Eighth Five-year Program has optimized the structure of land use,since 1995,coal mining industry has become more active gradually,which has promoted the structure of land use to optimize further.
