摘要

Liaohe Delta estuarine wetland is the largest estuarine wetland in northeast China, the article proposed eco-environmental evaluation indicators system for the wetland based on PSR model. By selecting indicators of pressure, state and response, we analyzed dynamic variations of the ecological environment and fragmentation status of the wetland. The results showed that the main pressure of the wetland is from agricultural production and urban expansion since 1988, which resulted in large-scale land reclamation, expansion of rice planting area and reduction of tidal flat areas. The internal structure and status of the wetland had experienced significant variations and the trend of fragmentation was evident. With negative effects of dwindling wetland resources, human-being's reasonable response to the variations of wetland status should be in three aspects: scientific classification of functional zones, conversion of appropriate economic model and adjustment of the industrial structure. Thus achieve the coordination of ecological protection and industrial economic development.
