The spatial distribution of vegetation is following a certain pattern determined jointly by factors like light, heat, rainfall and soil etc.

植被空间分布格局受光、热、水、土等的影响表现出一定的规律性。

Because of fragmentation, intersection and high heterogene of vegetation patches, vegetation landscape showed a very complex and mosaic distribution pattern.

由于植被斑块破碎，相互交错，空间异质性高，景观要素或者斑块类型表现出十分复杂的空间镶嵌的分布格局。

So the study of the effects on community structure and biomass of the soil nutrients, different distribution pattern is very important to the revelation of the law of vegetation succession.

因而研究土壤养分分布方式对群落结构和生物量的影响，对揭示植被演替规律具有重要的意义。
