利用1976年MSS遥感图像、1990年TM遥感图像进行判读制图,输出汾河上游地区土地利用/覆被分类图.应用GIS技术及数理统计学方法,结合土地利用分类动态度模型,对汾河上游地区1976年-1990年土地利用/覆被变化过程进行分析.结果显示,研究区在1976年到1990年14 a中草地、水体、城镇建设用地面积有所增加,耕地、林地、未利用地则有不同程度的减少.水体、草地面积有继续扩大的趋势,未利用地面积为持续缩小的变化趋势.其余三种土地类型,林地、城镇建设用地、耕地的面积则保持相对稳定的.
Land-used/cover change (LUCC) in the upper reaches of Fenhe River was researched based on remote sensing images in 1976, 1990. GIS technology, statistic methods, and land used classification dynamic degree model were used to reveal the temporal and spatial change of LUCC. The results indicated that the grassland area,water area and construction area were increased,and the area of cultivated land, woodland and unused land were reduced. It suggested that the water area, grasslandarea would be sequentially increased, the unused area would be decreased continuously, and the area of woodland, construction area ,the cultivated land area would be steady-going.
