patch density index 斑块密度指数
Distribution of farmland and grassland, patch density and diversity is affected by population density, climate and distance to coastal line. Negative relationship exists between distribution of farmland and grassland.
耕地、草地的分布、斑块密度、景观多样性与人口分布、气候、海陆位置有关;耕地与草地分布呈负相关;耕地分布较多的地区,景观整体的破碎度和多样性下降。
