摘    要:通过对各插值方法选择后取反距离加权法与克立格法对长湖的污染现状进行分析,结果表明大部分水域水质处于Ⅴ类和劣Ⅴ类,只有主要出水口习家口和刘岺闸附近的部分水域的水质可以达到Ⅳ类水质标准.同时发现反距离加权法与克立格法均具有较高的精度,但克立格法优于反距离加权法,这两种方法评价湖泊水质都能取得比较好的效果.

关 键 词:空间插值法  水质评价  长湖  空间  插值方法  长湖  水质评价  Spatial  Based  Lake  Water  Quality  效果  比较  湖泊水质  精度  发现  水质标准  出水口  水域  结果  分析  污染现状  克立格法

Abstract:The methods of inverse distance to a power and the Kriging were selected from the interpolation methods to describe the present situation of Chang Lake's pollution.The results indicated the water quality in majority of the Lake was in V level even worse,only near the main water outlet was in IV.The both methods of inverse distance to a power and the Kriging were high precision but the Kriging method surpasses the inverse distance to a power.The two methods all can obtain the quite good effect in evaluation of the lake water quality.
Keywords:Spatial interpolation  Water quality evaluation  Changhu Lake
