摘要
图们江下游发育珲春湿地、敬信湿地和防川湿地集中区,湿地类型包括河流、湖泡、沼泽和人工湿地等。采用遥感解译和野外调查方法,研究图们江下游湿地形成的条件,结果表明,图们江下游湿地形成受地质和人为条件控制,其中地质条件起决定性作用;提出控制图们江下游湿地形成的主要地质条件包括沉积地层、沉积物组合和构造活动;从湿地形成条件角度,分析图们江下游湿地的成因,将该湿地分为河流湿地和人工湿地2种成因类型,其中,河流湿地是古近纪以来新构造活动、特殊沉积物组合和河流改道等综合作用的结果,人工湿地是对原有湿地和河流人为改造的结果。
There are concentrated areas of Hunchun, Jingxin and Fangchuan wetlands developed in the lower reaches of Tumen River. The types of the wetlands include river, mire, take and artificial wetlands. The wet- lands＇ formation was controlled by the geological conditions and artificial conditions, but geological condi- tions took the basic function. The geological conditions of the wetlands＇ formation have been put forward by remote sensing and geographic information technology and field investigation methods. The geological condi- tions were the sedimentary strata, sediments assemblage and tectonic activity. The formation genesis of the wetlands has been analyzed based on the geological conditions of wetlands＇ formation. The genetic types in- cluded river and artificial wetlands has been proposed. The river wetlands were the synthetic result controlled by tectonic activity in paleogene, special sediments assemblage and river channel migration. The artificial wet- lands were the result of transformed from the original wetlands and rivers.
