中文摘要：
乌梁素海地处我国北方半干旱地区，属于典型的草型浅水湖泊且富营养化程度非常严重。由于受特殊的水文气象条件与河套灌区的影响，乌梁素海水环境污染问题必定有其特殊性，于是将地质统计学的理论与方法应用到乌梁素海水质参数空间数据分析中，尝试研究乌梁素海水质参数空间分布特性。结果显示：乌梁素海水质参数的空间结构变异性是客观存在的，各水质参数都具有块金效应，对乌梁素海水质参数进行克立格插值，并进行水体富营养化评价，乌梁素海从总排干以下至湖区中下部区域为重度富营养化；其余部分为中度富营养化，能够提供更为直观的水环境信息。研究结果对乌梁素海的水环境管理有一定的参考价值。
英文摘要：
Wuliangsuhai lake, which locates in the semi-arid region of northern China, is a typical grass-shallow lake and has serious eutrophication problem. Because of the impact of the special hydro-meteorological conditions of the region and Hetao Irrigation District, the water environment pollution problem of Wuliangsuhai has its special properties. With the measured spatial water quality data, the geo-statistics was used to characterize the spatial distribution of water quality parameters of Wuliangsuhai Lake. The re sults showed that the variability of spatial structure of the water quality parameters of Wuliangsuhai Lake was existed and each parameter showed the effect of nugget. Interpolation method with ordinary kriging was applied to identify the different levels of water pollution. The results showed that the eutrophication of Wuliangsuhai lake was serious between total draining canal and the lower part of the regional of Wuliangsuhai Lake, the rest was severe state, which gave more distinguishable information about the water quality. The study result were of instructive to the environmental management of Wuliangsuhai Lake.
