| 摘 要： | 综合利用DEM数据、地貌数据和1954-2000年5个时段的土地利用/覆被数据,分析了该流域近50a 来的湿地垦殖过程及其影响因素,结果发现:2000年的沼泽湿地面积仅为1954年面积的36.7%,而且80%左右的沼泽湿地都开垦为耕地.自然环境要素与农场建设对整个湿地的开垦过程产生了重要影响.分布于不同海拔高度与不同坡...

| Abstract: | Wetland cultivation and its influence factors in Naoli River watershed,a typical region in Sanjiang Plain,were analyzed by DEM data,relief data and data of land use and land cover for five periods of time from 1954 to 2000 obtained by RS/GIS technology.Results showed that the area of wetland in 2000 reduced to 36.7% of the original size in 1954,and nearly 80% of the area was turned into cropland.Natural environmental factors and the construction of farms had important impacts on the wetland cultivation proc... |
