| 摘 要： | 利用1989年、2000年和2008年3期扎龙湿地遥感资料,在ERDAS以及ArcGIS的支持下,通过监督分类与目视解译相结合的方法对影像进行分类以及分类后处理,以得到各种土地类型的面积,依据土地利用幅度的变化来研究土地利用类型变化,结果表明,研究区沼泽面积大量减少,盐碱地面积逐年增加,虽然人们开始退耕还草.增建人工湖泊,但湿地环境状况仍不容乐观.

| Abstract: | Using the series remote sensing data of Zhalong wetland of the year of 1989,2000,and 2008,with the support of ERDAS and ArcGIS,through the image classification and its post processing by the method of the supervised classification and visual interpretation,it acquired the area of each land types.It studied the change of land use type according to the change of land use range.The results showed that the area of swamp in study area greatly decreased,the area of salt-affected soils increased yearly.Although wi... |
