摘要
应用景观生态学理论,以桂林市2002年ETM+和2006年中巴资源卫星这两个时段的遥感图像为例,基于ERDAS IM AGINE等处理软件对遥感影像进行预处理、解译,获取不同时期的土地利用信息,了解景观生态过程变化趋势,探讨区域景观生态格局演变的关系.采用FRAGSTATS软件对景观指数进行计算,并对桂林市土地利用的景观格局进行分析,探讨了相关的人类活动对土地利用的影响.这一项研究对于了解区域生态环境变化,维护生态平衡,促进区域经济与环境的协调发展具有重要意义.
Based on landscape ecology theory, by using Guilin 2002 ETM＋ and 2006 the Chinese and pakistani resources satellite these two time interval remote sensing image. Used ERDAS IMAGINE to pretreatment,interpret- ation the image so that gain the different time land utilization information,find out the current of landscape change process, discuss the change relationship of landscape ecological pattern. Used FRAGSTATS calculate the landscape index, and analysis the landscape pattern to realize Guilin＇s land utilization, discussed the relationship between human activities and land utilization. This paper study for understanding the regional ecological environment, maintain ecological balance, and practicability for promote regional economic and environmental development.
