摘要
以长白山自然保护区为研究对象,利用野外实地调查和3S技术相结合,根据湿地所处立地特征,建立长白山自然保护区湿地分类系统,探讨长白山自然保护区湿地类型划分.河流湿地、湖泊湿地、高山湿地、人工湿地等可以通过ALOS卫星影像和地形图等获得.沼泽湿地无法用传统的方法获取,主要通过野外实地调查获取信息.根据长白山自然保护区自然环境状况选取湿地调查区域,然后利用GPS仪对各区域进行定位考察,记录湿地的立地,进而确定湿地类型.结合长白山自然保护区湿地分类体系,使用ArcGIS9.3软件进行多源数据叠加,绘制出研究区的湿地分类图,在此基础上分析长白山自然保护区湿地类型特征.研究表明,长白山自然保护区湿地类型极为丰富,沼泽湿地是本区主要湿地类型,高山湿地次之,人工湿地最少.长白山自然保护区湿地的形成,受地貌和水文影响较大.
Field investigation and 3S technology were used to characterize wetland types and to establish wetland classification in Changbai Mountain nature reserve. To explore wetland division, data of river wetlands, lake wetlands, alpine wetlands, artificial wetlands were obtained from ALOS satellite imagery and topographic maps. Marsh information was obtained by field investigation. Wetlands survey areas were selected according to natural environment, GPS was used to locate regional visits, record site of wetlands to determine wetland type. ArcGIS9. 3 was used to superimpose multi-source data and map out wetlands classification, to analyze wetland characteristics. There are abundant wetlands resources in Changbai Mountain nature reserve, swamp wetland are widely distributed. The main factors leading to difference between wetland types were found to be drology, soil, vegetation, geomorphology. Geomorphology and hydrology were dominant factors controlling wetland formation.
