Abstract

To improve the increasingly degenerating environment of the wetland in the estuarine delta of Diaokou River, the Yellow River Conservancy Commission conducted ecological water supplement to the wetland during the water and sediment regulation period in 2010. In this study, we analyzed the landscape patterns before and after the event. HJ-1B CCD data were adopted to monitor the dynamic changes of Diaokou River in national reserve of Yellow River Delta, and the ArcGIS and FRAGSTATS softwares were used to analyze the landscape patterns. The result shows that the ecological efficiency from the ecological water supplement to Diaokou River is remarkable. The landscape contagion index and landscape shape index decreased, while the edge density and mean patch area increased from 2009 to 2012 which led to a decrease in landscape heterogeneity. The Shannon diversity index increased, and the landscape contagion index decreased in the meantime, which resulted in decreased landscape connectivity. Shape of vegetation patches became more regular. The results showed the dynamic characteristics of landscape pattern in Diaokou River before and after the ecological water supplements, which provided the scientific basis for ecological regulation and wetland restoration.
