【摘要】 对汾河源头土地利用的动态变化情况进行分析,采用30年来的遥感影像,应用地理信息系统与遥感技术,解译出各个年代的土地利用类型后统计出各种类型的面积,从而分析研究区土地利用的动态变化情况。结果表明:研究区内林地、草地和耕地为主要土地利用类型,所占比重最大,合计占90%以上;30年来,土地利用类型的主要变化趋势是耕地与草地减少,多转化为林地和居住地,林地与居民建设用地增加。更多还原

【Abstract】 The dynamic change situations of land use in the headstream region of Fenhe River were analyzed.Based on the remote sensing image during 30 years,the land use types in different year were interpreted by using geographical information system and remote sensing technology.And then the area of different types of land was counted and the dynamic change situations of land use in the research area were analyzed.The results showed that woodland,grassplot and cultivated land in the research area were the main land use types,and the proportion was greatest and reached over 90%.During recent 30 years,the main change trend of land use types included the decrease of cultivated land and grassplot,the transformation of cultivated land and grassplot to woodland and residential land,and the increase of woodland and resident construction land.更多还原
