| 摘 要： | 基于现场的采样数据,结合河流自身特点,应用地质统计学的理论和方法分析了苏南某城市河流水质参数的空间变异规律及其原因。研究结果表明,根据变差函数模型分析,发现研究区河流3个水质参数在一定范围内存在空间相关性;研究区河流的CODMn呈现中南部较高,其他部位相对均匀的趋势,CODMn的空间变异性主要是由居民的日常活动及河道的自身特点引起;研究区河流的TP和NH3-N含量严重超标,水体富营养化程度严重。TP和NH3-N的空间变异性相似,含量较高区域集中在研究区的西南部、东南部和东北部,其空间变异性主要由工业活动和居民日常生活共同作用引起,其中工业活动占主导作用。

| Abstract: | Based on the investigation data, and combined with the own characteristics of rivers, the theory and method of geostatistics were used to characterize the spatial variability of water quality parameters in rivers of some city in south of Jiangsu and analyzed its causes. The results showed: According to the analysis by variogram model, we found three water quality parameters of rivers had spatial variability in a given spatial range. In this area, the content of CODMn in central and southern rivers showed higher than other parts, and spatial variability of CODMn was mainly caused by the daily activities of residents and the own characteristics of rivers. The content of TP and NH3-N in the rivers exceeded the standard seriously, so the water in this area showed more rich nutrition. The spatial variability of TP and NH3-N were similar and it showed higher district were all in southwest, southeast and northeast of the area. Their spatial variability was mainly caused by industrial activities and daily life of residents, and industrial activities played the leading role. |
