摘要: 基于1987,1997和2008年夏季的Landsat卫星影像,在RS和GIS支持下利用景观分析软件Fragstats3.3和景观生态学的理论,分析了南四湖湿地1987—2008年间土地利用变化特征以及各土地利用类型间的转化情况和景观指数变化特点。结果表明:1)湿地景观格局的总体特征是:景观格局变化显著,自然景观面积减少,人工景观面积增加;景观斑块破碎化加重,其中芦苇地、荷田和养殖水面景观格局变化最为剧烈。2)从景观指数方面看:类型水平上,不同景观类型的指数变化规律不同,体现不同的变化特征;景观水平上,斑块数量和斑块密度持续增加,平均斑块面积和蔓延度指数不断减小,Shannon多样性指数和均匀度指数则是先增大后减小。3)从转移矩阵看:1987—1997年景观格局变化相对和缓;1997—2008年景观格局变化相当剧烈;各种地类相互转化的比例较高,特别是芦苇地和荷田两种湿地自然景观面积转出的比例很大;并且转化更多的是自然景观转化为人工景观,体现了湿地明显的人为扰动特征。

Abstract: By using 3 periods TM/ETM+ remote sensing data in 1987,1997 and 2008 and based on remote sensing,geographic information system and landscape ecology theory,selecting landscape pattern index in type level and landscape level,the quantitative analysis of the dynamic changes Shandong Nansihu wetland landscape pattern has been done in the paper.The results show that:(1)The general characteristics of landscape pattern are that significant changes have been found,the area of natural landscape decreasing and area of artificial landscape increasing.The degree of patch fragmentation is aggravating.The landscape patterns of reed land,lotus land and fish pond change most intensively.(2)with a view to the landscape index:at the type level,different landscape types have different change characteristics of index .At the landscape level,the number and density of patches have been increasing ;average patch area and contag index have been declining.Shannon diversity index and evenness index have been firstly increasing,then decreasing.(3)Looking from the transfer matrix,the changes of landscape pattern of Nansihu have begun in the former study period(1987-1997);and the rate of landscape pattern changes has become faster in the late study period(1997-2008).Every landscape changes to each other on a high rate,especially the landscapes of reed and lotus own very high rate of changing to other landscapes,and this transformation tends to happen from natural landscape patches to artificial landscape patches.

Key words: landscape pattern, dynamic change, landscape index, Nasihu wetland
