南四湖湿地景观空间格局动态演变
Dynamic evolution of wetland landscape spatial pattern in Nansi Lake, China
摘要
Abstract
Based on Landsat images in 1987,2002 and 2014 from Nansi Lake located in Shandong Province,landscape pattern index,dynamic index,landscape gradient and gridding model were used for analysis of the wetland distribution in the lake.The results showed that the landscape contagion index and aggregation index gradually decreased from 1987 to 2014,while the landscape diversity index and evenness index gradually increased.The distribution of landscape area was more uniform while its patterns trended to be fragmented.Human activities impacted Nansi wetland distribution and the disturbance presented an increasing trend.The total area of Nansi wetland gradually increased during the study period.The area of lake first decreased then increased,and the area reached the maximum in 2014.The area of the ponds along the riparian zone had increased gradually,but the increasing speed slowed down.The area of the rivers remained stable,while the area of the swamps decreased continually during the period.The change of landscape pattern of Nansi Lake wetland mainly resulted from agricultural activities,establishment of Nansi Lake Natural Reserve,and the South-to-North Water Diversion Project.关键词
