Study on wetland resources in deltas around Bohai Sea

Abstract

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. Problems in using and conserving wetland resources are shown in the paper, which aim to provide basis for the further study on the landscape ecology, function, and sustainable use of wetlands in the deltas. The study shows that the wetlands in the two deltas are characterized by great variety of wetland 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 successfully solve the contradiction between development and protection. At present, the most pressing matter of the moment is to protect environment and control pollution.
