摘要
为了探究内梅罗指数法在北戴河国家湿地公园水质评价中是否合理有效,应用修正前后的内梅罗指数法对北戴河国家湿地公园水质进行评价。结果表明:修正前后的内梅罗指数法在水质评价上有所差异,内梅罗指数与综合水质标识指数和营养状态指数均有较好的相关性,其中修正内梅罗指数Ⅱ与综合水质标识指数和营养状态指数相关性最佳,相关系数分别为0. 84、0. 762。通过对比分析,修正内梅罗指数法Ⅱ在北戴河国家湿地公园水质评价中具有更好的适用性。
In order to explore whether Nemerow index method is reasonable and effective in the water quality evaluation of Beidaihe National Wetland Park,the modified Nemerow index method was applied to evaluate its water quality. The results showed that the modified Nemerow index method had some differences from the other methods in water quality evaluation of Beidaihe National Wetland Park. The Nemerow index had good correlation with comprehensive water quality index and nutritional status index. Among them,the modified Nemerow index Ⅱ had the best correlation,and the correlation coefficients with comprehensive water quality index and nutritional status index were 0. 84 and 0. 762,respectively. Through comparative analysis,the modified Nemerow Index Ⅱ method may have better applicability in water quality assessment of Beidaihe National Wetland Park.
