基于遥感与GIS技术的升金湖地区景观格局动态分析

Landscape Dynamic Change Pattern of Shengjin Lake Delta Based on TM Imagery and GIS

根据1987，1998和2004年TM影像和研究区1980年地形图，利用RS和ARC／INFO进行解译，得到研究区3个时期土地利用图，在此基础上分析升金湖地区1987～1998年和1998～2004年两个时期土地利用和景观格局变化。结果表明，升金湖地区土地利用变化是显著的，既有面积变化，又有空间格局的转换，面积变化和空间上变化不同年段呈现特点有共性也有特性；土地利用变化是自然因素和人为因素综合作用的结果，其中人为干扰是变化的主导因素。

Based on TM Data in 1987, 1998 and 2004 and the relief maps of 1980, this study aimed to draw the land use maps of the research area in three different periods by using the RS and ARC/INFO and analyze the land use change landscape pattern change in two periods （1987 -1998 and 1998 -2004）. The result showed that the changes of Shengjin Lake Delta were remarkable both in area and spatial pattern and the characteristics of the changes had similarity and peculiarity with each other. Both natural factors and artificial factors contributed to the land use changes in which the artificial factors were the dominant ones.
