With a large area, various types and complex landscape structure, wetlands in the Liaohe and Huanghe Deltas have substantially benefitted the regional economic development. Based on the classification system of wetlands, the present situation and distribution characteristics are studied through RS and GIS techniques. At present, there are 314,857 ha of wetlands in Liaohe Delta,accounting for 79.5% of the total urban area; among which there are 159,919 ha of natural wetlands and 154,838 ha of artificial wetlands, accounting for 50.8% and 49.2% of the total wetland area, respectively. In Huanghe Delta,the total wetland area is 333,427 ha,being 42.7% of the total urban area; and there are a natural wetland area of 229,329 ha,and artificial wetland area of 104,098 ha,accounting for 68.78% and 31.6% of the total wetland area, respectively. Because of the regional resources exploitation for many years, wetlands have changed a great deal both in area and structure. Some strategies concerning protection of ecological function of wetlands and solution to the problems of the sustainable development between resources exploitation and wetland protection are put forward in this paper.
