The effects of spatial scales on landscape indices —A case study of Beijing

Taking into consideration the importance of particle effects in landscaping structure, the thesis adopted 8 landscaping indexes to analyze the feedback of landscaping structure towards particle wearing and gathering in Beijing major districts. And it comes to a conclusion that PLAND, SHDI and SHEI show less sensitivity to particle change, NP, LPI, LSI CONTAG and AWMSI is on the contrary very sensitive. Meanwhile, the thesis discussed relations between particle change and spatial resolution in landscaping structure analysis as well as selectivity of scale field and particle effects therein. Spatial resolution turns out an unignorable factor in analyzing landscaping structure. When analyzing landscaping structure, adjustment should be introduced in image resolution and special granularity in accordance with needs of various research purpose.
