Abstract: The vulnerability of wetlands to climate change depends on the position where the wetlands develop.The basic thought of hydrological landscape was simply presented,and the main wetlands in Northeast China classified into several types,i.e.wetlands in glacial-etching landscapes,wetlands in mountainous landscapes,wetlands in estuary delta landscapes,wetlands in coastal lowland landscpes,wetlands in flood plain landscapes,wetlands in terrace depression and ancient river channel depression landscapes,wetlands in piedmont depression landscapes,wetlands in lake and lake fringe depression landscapes,and wetlands in semi-arid and semi-humid prairie depression landscapes.Finally,the vulnerability of wetlands in various landscapes was evaluated,classified by low,low-medium,medium-high,high and extreme levels.
