| 摘 要： | 在景观生态学研究方法的指导下,本文利用遥感和GIS技术,采用半变异函数分析,选取多样性指数和斑块密度,对厦门市不同幅度下的景观格局进行探讨。首先选取出厦门市景观格局研究的最佳幅度,然后在此基础上,对最佳幅度下的景观指数进行克里金空间插值分析,研究厦门市景观格局的空间异质性特征。结果表明,3km幅度是研究厦门市空间变化的一个比较好的幅度,3km幅度下,景观多样性指数可分为三个区域,斑块密度可分为三个层次。

| Abstract: | Based on landscape ecology theory,using remote sensing and GIS technology,landscape pattern of Xiamen city at different extents was discussed and the best extent was chosen with techniques of semi-variogram,diversity index and patch density.Then,Kriging interpolation of landscape index at best extent was analyzed and spatial heterogeneity of landscape pattern was studied.The conclusions were drawn as follows: The best analyzed extent of landscape pattern in Xiamen city was 3km.At 3km extent,diversity index in Xiamen city could be divided into three regions as follows: the highest value areas were distributed in the urban and rural combined areas where many landscape types were scattered interlacedly;the secondary high value areas had multiple centers;the lowest value areas were distributed in the downtown and mountainous regions that had single landscape type.Patch density was divided into three regions as follows: the densest areas were distributed in fragmentation patch regions;the least dense areas were distributed in the north and north-west covered by forest areas and high-economically developed downtown,where the landscapes type were both single;meanwhile,the less dense areas were located in between. |
