中文摘要	以新疆精河流域为研究对象,运用GIS和地统计学的原理与方法,对该区域的pH,水溶性盐分,速效钾,有效磷,碱解氮,有机质等土壤质量要素的空间分异规律进行了定量分析.结果表明:1)流域内土壤质量要素的空间异质性明显,人类的干预程度严重影响土壤的空间异质性;各土壤质量要素的空间变异程度不同,其排列顺序依次为有效磷>有机质>碱解氮>速效钾>电导率>pH值.2)六种土壤质量要素变异函数理论模型不同:pH的理论模型很好的符合线性模型,有机质,速效钾和电导率的理论模型很好的符合指数模型,有效磷和碱解氮则也较好的符合球状模型.3)六种土壤质量要素在南北,东西,东北-西南,西北-东南四个方向上的各向同性表现的范围不尽相同:碱解氮和电导率在不同方向上都表现出各向同性;pH,有机质和速效钾次之,在南北,东西和东北-西南三个方向上的变异函数的变化大致相同,在西北-东南方向上波动较大;有效磷在各个方向上的空间变异程度都很大,这主要是由于艾比湖湖岸-绿洲-荒漠-山地一线(西北-东南方向)地质,地貌等自然因素差异悬殊造成的
英文摘要	GIS and the fundamentals and methods of geostatistics were applied to regionalize the spatial distribution pattern of pH,EC, Available Potassium, Available Phosphorus, Available Nitrogen and Organic Matter in Jinghe Basin. The results showed that:①It is clearly founded that the spatial heterogeneity of the soil quality in Jinghe basin was obvious, and the human activities had seriously impacted on the spatial heterogeneity of soil quality. The order in spatial variation of different soil quality element was: available phosphorus > organic matter > available nitrogen > available potassium > electric conduct rate> pH.②The theory model of pH well fitted the linear model, the theory models of organic matter, available potassium and electric conduct rate well fitted the index model, and the theory models of the available phosphorus and nitrogen well fitted model.③Six soil quality elements in four directions, including North-South, East-West, North East-South West and North West-South East, had the different isotropy. The available nitrogen and electric conduct rate both demonstrated isotropy in different directions;pH, organic matter and available potassium took the second place;Available phosphorus demonstrated the larger spatial variation degree in different directions. All the changes of isotropy were mainly due to the natural factors differences from the lake bank-Oasis-Desert-mountain(Northwest-Southeast direction)
