摘要: 通过对北运河下游土壤的取样,采用地统计的方法分析北运河流域农田土壤pH、碱解氮、有效磷、速效钾和有机质五种养分的空间分布规律,结合武清区土壤类型和其他的相关资料的数据进行分析,结果表明:土壤类型对土壤pH、有效磷分布有影响,对土壤pH影响尤为明显;北运河流域的水系对碱解氮、有机质空间分布影响较大,水系发达的区域含量明显高于水系不发达的区域;速效钾多是由其他因素引起。

Abstract: In this paper, based on samples from the downstream district along the Beiyunhe River, the soil nutrients such as pH, available nitrogen, available phosphorus, available potassium, and organic matters were analyzed by the geostatistical method. Combined with the basic data of Wuqing’s soil type, the relationship of the different nutrients’spatial distribution was found that the spatial distributions of the pH and available phosphorus are similar to the soil type more or less, and the reason is that soil pH and available phosphorus are influenced by the soil type, and the effect on soil pH is significant; Beiyunhe river system has a great influence to the spatial distribution of available nitrogen and organic matters, the contents of which in high-density river system regions were significantly higher than those in lower-density river system regions. Available K mostly caused by other factors.
