基于遥感的龙口市景观格局演变分析

Study on Dynamic Change of Landscape Pattern of Longkou Municipality based on Remote Sensing Data

利用ERDAS遥感解译软件对龙口市1992年,2000年2期遥感影像数据进行解译处理,利用FRAGSTATS软件计算景观类型、景观2个等级水平的指数,分析龙口市景观格局变化。结果表明:1992—2000年龙口市果园、旱地、城乡建设用地面积明显增加,水浇地、林地面积减少,还对龙口市景观格局演变进行驱动力分析。

Two phases of remote sensing image data taken respectively in 1992 and 2000 were interpreted through ERDAS software and the change in landscape pattern of Longkou Municipality was analyzed with two categories of indices from the landscape pattern and landscape levels by means of using FRAGSTATS software. The results showed that the orchard land area, farming land area without irrigation facilities and the construction land area significantly increased, while the irrigated land area and forested land area decreased. The reasons for the change in landscape pattern were also analyzed in the paper.
