| 摘 要： | 以浙江省安吉县黄泥岭红壤小流域为研究对象,通过栅格取样法,分析了不同样点的土壤性状,利用地统计学和地理信息系统(GIS),研究了该小流域土壤的空间异质性和格局.结果发现,小流域内土壤的空间异质性明显;统计变异的大小顺序为:速效钾>速效磷>全氮和有机质>pH值;土壤有机质与全氮量空间变化趋势相似,且相关性极显著;速效磷和速效钾的空间格局相似性较大;人类干预严重影响土壤的空间格局.

| Abstract: | Huangniling red soil watershed in Anji county of Zhejiang province is selected as a case study, soil properties of different samples are analysed by use of grid cell method, soil spatial heterogeneity and pattern are studied with the supporting of geostatistics and geographic information system (GIS) The results show that: soil spatial heterogeneity of this watershed is evident; orders of Cv (Coefficient of Variation) are: quick acting K>quick acting P>total N and content of organic matter >pH ; the spatial tendency of total N and content of organic matter is similar and they have closely linear relationship; the spatial pattern of quick acting P and quick acting K is also similar; soil spatial pattern is deeply affected by human activities |
