采样分布

According to the channel transverse,hydrological condition,sewage outfall distribution,and branch status,experimental samples were collected from eight crosssections in the Wanzhou section of the Yangtze River and Zhuxi River.

按照河床形态、水文条件、排污口分布、支流状况等特点从长江万州段及长江支流苎溪河选取8个断面进行采样，对水样中溶解性有机物的荧光光谱特征进行了分析和研究。

The results show that the variograms of As, Cd, Pb and Zn exhibit anisotropy, which possibly is controlled by the distribution of ore deposits; Hg behaves strong nugget effect, which is influenced by smallscale factors, and the further study should increase the sample density.

结果表明，As、Cd、Pb、Zn元素的变异函数表现为各向异性，其方向性可能主要受矿床分布控制；Hg元素块金效应较大，表明其受小尺度因子影响较大，其进一步分析须增加采样密度。
