查询词典 systematic sampling

Based on grid pattern sampling, by the analysis of lacunarity indices in Huairou and Mentougou District, it is found that: In different scales, the higher lacunarity indices are, the greater heterogeneity of spatial distribution for forest landscape elements is. This performance can be considered as macroheterogeneity characteristics. Oppositely, the lower lacunarity indices values are, the smaller heterogeneity of spatial distribution for forest landscape elements are.
