摘　　要：Based on the data of wetlands in Huanghe delta and Liaohe delta which were go by the combination of Remote Sensing(RS), Geographical Information System(GIS) and Global Position System(GPS), the paper discusses the sindlarities and differences of wetlands in the two regions by comparing them in composition, distribuhon, spatial pattern of landscape and ecology. Problems in using and conserving weiland resources are shown in the paper, which aimto provide basis for the further study on the landscape ecology, function, and sustainable use of weilands in the deltas. The study shows that the wedands in the two deltas are characterized by peat variety of weiland types, distribution with the shape of strip, abundant resources of wild plants and animals, intense effects of human activities on the structure of the landscapes, broad prospects for development and great environmental pressure. It is necessary to successfull solve the contradiction between development and protection. At present, the most pressing matter of the moment is to protect environment and control pollution.Based on the data of wetlands in Huanghe delta and Liaohe delta which were got by the combination of Remote Sensing(RS), Geographical Information System(GIS) and Global Position System(GPS), the paper discusses the similarities and differences of wetlands in the two regions by comparing them in composition, distribution, spatial pattern of landscape and ecology.
