摘  要：
以新疆博尔塔拉河、精河下游河岸带土壤为研究对象,针对土壤中的有机质、碱解氮、速效磷、速效钾等指标进行定量测定,运用地统计学方法分别对博尔塔拉河、精河流域土壤养分空间分布特征进行了分析。结果表明:博尔塔拉河下游河岸带土壤有机质、碱解氮变异程度大于精河下游河岸带,土壤速效磷、速效钾变异程度相近;两河土壤速效养分垂直分异规律为:土壤有机质、碱解氮含量均随土层深度的增加而递减;水平分异规律为:距离艾比湖入湖口越远,土壤中速效养分平均含量越小。总体而言,博尔塔拉河下游河岸带土壤速效养分高于精河下游河岸带土壤速效养分,精河土壤养分空间异质性较小。

摘  要：
Soils in Bohe and Jinghe River riparian were selected as samples.The soil organic matter,available N,available P and available K content under different types of vegetation were measured.Spatial distribution and statistical characteristics of soil nutrients of two riparians were analyzed by using the geostatistics.The results showed that variations of the soil organic matter,available N of Bohe river were greater than those in Jinghe river,variation of soil available P and available K was smaller.Vertical distribution rules of the soil available nutrients were characterized as that soil organic matter and available nitrogen content decreased with the increase of depth.Horizontal distribution rules of soil available nutrients demonstrated that the mean content of soil available nutrient was lower with the increase of distance from Ebinur lake.Overall,the soil available nutrient contents in Bohe river riparian zone were higher than those in Jinghe river,and the spatial heterogeneity of soil nutrients in Jinghe river was smaller.
