摘要
针对湖泊富营养状态Ｈａｍｍｉｎｇ贴近度评价模型存在的“阈值漂移”问题，重新构造了评价参数隶属函数，提出了一种湖泊营养状态Ｅｕｃｌｉｄ贴近度评价模型，经过对全国２３个湖泊富营养状态的实例分析，证明这种评价模型结构合理，评价过程简单，模型通用性好。
he attaching function of evaluated Parameters was rebuilt because of 'threshold drift' in osculation assessment mode. The evaluated model of Euclid osculation for trophic state of lake was put forth. This model was proved to have a reseasonable structure simple process and satisfaction in common use, on the basis of the practical analysis on the eutrophication of 23 lakes in China.
