The Response of Wetland Ecosystem Services to Landscape Pattern of the Yangtze River Economic Belt during Four Periods
The landscape pattern change of the wetlands can not only lead to alterations in wetland ecosystem processes,components,structure and biodiversity,but also has a significant impact on the services of the wetland ecosystems.Therefore,revealing the relationship between landscape pattern and wetland ecosystem services is of great significance for wetland conservation and rational utilization.By using the land use remote sensing monitoring data of the Yangtze River Economic Belt in 2005,2010,2015 and 2020,and applying the In VEST model,this paper studied the habitat quality services,carbon storage services and water purification services of the wetland ecosystems in the Yangtze River Economic Belt during 4 periods and their changes,and analyzed the relationship between wetland ecosystem services and landscape patterns.The results showed that in 2005,2010,2015 and 2020,with the passage of time,the total area of the wetlands in the Yangtze River Economic Belt was decreasing,and the wetland landscape tended to be fragmented;the level of habitat quality service of the wetlands has increased slightly,and the levels of carbon storage service and water purification service have declined.
