六盘山华北落叶松人工林土壤水分空间异质性的降雨前后变化及其影响因素
Shuitu Baochi Xuebao, 2016 为了阐明林冠叶面积指数、枯落物厚度等植被因子及降雨量影响下的林地土壤水分空间异质性变化规律，在宁夏六盘山香水河小流域选择了2个35 a华北落叶松典型坡面（东南坡A、南坡B），遵循空间格局分析的小支撑、多样点设计原则，结合所选坡面特征，利用线状样带取样法，测定了坡面上各样点的表层（0—20 cm）和亚表层（20—40 cm）土壤水分、林冠叶面积指数、枯落物层厚度、坡度及离开最近一棵树主干的距离，采用经典统计结合地统计学方法，分析了降雨前后土壤水分空间变异特征 ...

Shuitu Baochi Xuebao, 2005 分别在2 0 0 3年枯水期与丰水期对洮儿河流域平原区潜水系统进行取样分析,运用空间变异函数和克立格插值法对潜水总溶解固体(TDS)时空变异特征分析,研究结果表明:(1)潜水TDS季节变化不明显,而且呈现明显的分带性;(2 )TDS空间变程较大,主要受区域水文地质条件、地形地貌、土壤类型等大尺度因子影响;(2 )局部地区潜水TDS出现异常,已受外界盐分污染 ...
