厦门岛土地利用格局空间尺度分析

基于SPOT2.5m遥感影像数据和地理信息系统技术,运用景观生态学原理,通过分析不同粒度条件下景观格局指数的变化特征,研究厦门岛土地利用景观格局对于空间尺度变化的响应,以期寻找研究区土地利用景观格局分析的适宜粒度。结果表明:除面积比例对粒度变化弱敏感外,其余所选景观指数对粒度变化相对敏感,体现出一定的尺度依赖性,因而在进行景观格局分析时要考虑尺度效应;在研究区进行土地利用景观格局分析的适宜粒度为10m。

An analysis on the land use pattern of Xiamen Island based on different spatial scales

Based on SPOT remote sensing images and GIS,choosing the landuse of Xiamen Island as a case study object,and by using the methods of landscape ecology,the paper studied the spatial scaling effect of the landscape pattern with different grains by analyzing the changes of landscape indices characteristics under different grains.Moreover,the paper found the appropriate scale for the analysis of landuse landscape in the study area.The result demonstrated that: in the study area,the PLAND was weakly sensitive pattern indices to grain,other indices were relative sensitive to grain and had spatial dependence,that mean the scaling effect should be consider when studying the landscape pattern;the appropriate scale for the analysis of landuse landscape of the study area was the grain 10m.
