摘要:本论文以南京晓庄学院方山校区为例,选取合一广场和图书馆旁河边2个研究地点,对不同类型植被(乔木、灌木及草本植物)覆盖下的土壤粒径进行分析。结果表明不论乔木,灌木还是草本植被下土壤质地都不均匀。草本植被下土壤的细颗粒,即粉粒和粘粒含量相对多些。草本植被下土壤的质地最不均匀,不像乔木和灌木下的土壤那样颗粒比较集中在某个狭窄的范围内。景观植物中同一类型的植被覆盖下的土壤分布在两个不同地点,其粒径分级基本相似。

关键词:粉粒;粘粒;不同植被; 土壤粒径分布;方山校区

 

Abstract: This paper is to select the Heyi Square and the library river in nanjing xiaozhuang college campus as the targets, and analysis the distribution characteristics of soil particle sizes in different kinds of vegetation covers (trees, shrubs, and herbs). The results show that any vegetation texturer has the uneven distribution patterns. The content of silt and clay in Herb vegetation is more than others. Soil texture of Herb vegetation is the most uneven, which is unlike the content of trees and shrubs focusing on a narrow range. To the same type of vegetation coverage of landscape plant, the soil particle of the soil distribution in two different locations is basically similar. 

Key words: silt ; clay; different vegetation; soil particle size distribution; Fangshan campus
