2014年对浙江省临安市、余杭区的雷竹(Phyllostachys praecox cv.prevernalis)林地表层(0~30 cm)土壤的pH、有机碳、碱解氮、有效磷和速效钾的含量进行测定,分析其的空间变异特征及影响因素.结果表明,林地土壤的土壤有机碳(18.3 g?kg-1)、碱解氮(159.7 mg?kg-1)、有效磷(119.1 mg?kg-1)、速效钾(192.3 mg?kg-1)含量高,pH值较低(5.0);土壤肥力的空间分布特征为:pH值北低南高,有效磷和速效钾为北高南低,而碱解氮、有机碳则呈西南高、东北低的趋势;经营措施显著影响着土壤有机碳、碱解氮的空间分布(P<0.05),土壤pH、有效磷、速效钾的空间变化同时受到土壤类型和人为经营的显著影响(P<0.05).%Determinations were implement in 2014 on soil fertilities, such as pH, organic carbon, alkali-hydrolysale nitrogen, available phosphorus and available potassium at 0-30 layer in Phyllostachys praecox cv. prevernalis stands in Lin'an and Yuhang, Zhejiang province. Analysis were made on spatial variation character. The result demonstrated that contentw of organic carbon, alkali-hydrolysale nitrogen, available phosphorus and available potassium were higher, but pH was lower. Spatial distribution of pH was lower in the north part and higher in the south, that of available phosphorus and potassium higher in the north and lower in the south, and that of organic carbon, alkali-hydrolysale nitrogen higher in the southwest and lower in the northeast. Investigations showed that management measures of the stands had great effect on spatial distribution of organic carbon, alkali-hydrolysale nitrogen, while spatial distribution of pH, available phosphorus and potassium was influenced by soil types and management measures.
