摘要
以1990年、2000年与2010年车尔臣河流域Landsat-TM影像数据和中巴资源卫星数据,采用GIS技术分析研究区20 a土地利用/覆被变化。结果表明,1990—2010年,研究区耕地、水域湿地和建设用地呈现增加趋势,分别增加152.69%、343.05%、34.09%,其他用地类型变化不大;新增耕地面积主要来自于3.9%的草地;新增水域湿地面积主要来自于2.63%的沙地和2.03%的草地。研究结果可为区域水土资源可持续利用及生态环境保护提供参考。
This paper uses GIS technology,and the TM image data in the year 1990,2000 and 2010 respectively,and the CMB resource satellite data in Qarqan River Basin to analyze the land use/cover change in study area in the past 20 years.The results show that from 1990 to 2010,the farmland,wetland and construction land presented increasing trend,with an increase by 152.69%,343.05%,34.09% respectively,and the other land use/cover has little change; the newly increased farmland mainly comes from 3.9% of grassland; newly increased wetland mainly comes from 2.63% of sand and 2.03% of grassland.The results can provide reference for the sustainable utilization of regional water and soil resources and ecological environment protection.
