中文摘要：

选取8个常用的景观指数，以厦门岛土地利用格局为例，分析景观指数随粒度变化的基本规律。探讨尺度效应对景观格局的影响，为基于景观指数进行不同尺度下土地利用类型、土地利用格局变化预测、对比分析和评价等研究提供参考。结果表明：在研究区内景观类型特征和景观格局特征随粒度的增大出现了显著的变化；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，因而利用这些景观指数进行不同尺度下的景观格局分析时需考虑尺度效应。

英文摘要：

Chosen the land use of Xiamen Island as an experimental area, the paper analyzes the characteristics of the change of 8 landscape indices （such as NP, PLAND, TE, PAFRAC, LSI, SHDI, SHEI and CONTAG） associated with the increase of grain and confers the influence of spatial scaling effect on the landscape in order to provide reference for the researches such as the change forecast, comparison analysis and evaluation of the landuse types or landuse pattern among different grains based on the landscape indices. The result demonstrates that ： （ 1 ） the characteristics of landscape types and landscape pattern of the study area change significantly with the increase of grain; and （2） in the study area, the PLAND is a pattern indices weakly sensitive to grain change that means the PLAND can be directly used under the range of reaches grains for landscape pattern study, and other indices （such as NP, TE, PAFRAC, LSI, SHDI, SHEI and CONTAG） are relative sensitive to the grain change and reflect certain spatial dependence, that means the scaling effect should be considered when studying the landscape pattern with different grains based on these landscape indices .
