摘要
采用模糊评价模型对湖北省武汉市东湖10个湖区的富营养化水平进行评价,评价对象与标准对象的相似程度采取海明距离进行处理。计算可知,东湖占42.6%面积的区域属中等营养水平,5.8%面积的区域为富营养化水平。评价结果表明,东湖10个湖区中有2个湖区是富营养化水平,4个是中等营养化水平。
Fuzzy assessment model is used to assess eutrophic state of ten lake areas in Donghu Lake of Wuhan City. The resemblance between the object and the criterion is denoted by Hamming distance. Results show that mesotrophic water constitutes 42.6 % of total water area, and the area of Lake. It indicates that two of the ten lake areas are in eutrophication is 5.8 %, including Miaohu Lake and Shuiguohu a state of eutrophication, while four of them are in mesotrophic status.
