摘　　要：在RS和GIS技术支持下,获取了2000年和2015年三江平原2期土地利用数据,并对三江平原土地利用方式的动态变化进行了定量研究。结果表明在这15年里,三江平原的土地利用方式发生了显著变化。耕地增加了6868.2km^2,其中湿地、林地与草地对耕地的增加贡献最大。湿地减少了1236.08km^2,林地减少了2924.5km^2,草地减少了2473.52km^2。建设面积增加了112.63km^2,水域减少了316.27km^2。因此,耕地变化是驱动三江平原其他土地利用方式变化的直接因素。Based on the support of RS and GIS,the land use data of the two periods in the Sanjiang plain in2000and2015were obtained,and the dynamic changes of land use patterns in the Sanjiang plain were studied quantitatively.The results show that the land use pattern of Sanjiang plain has changed significantly in the15years.Farmland increased by6868.2km^2,of which wetland,woodland and grassland contributed most to the increase of farmland.The wetland decreased by1236.08km^2,woodland decreased by2924.5km^2,and grassland decreased by2473.52km^2.The construction area increased by112.63km^2and the water area decreased by316.27km^2.Therefore,farmland change is a direct factor driving the change of other land use patterns in the Sanjiang plain.
