| Abstract: | Through selection of ecological factors affecting wetlands,the paper classifies ecological environment of wetlands into 5 types based on principal components analysis and grey sequence analysis.The paper also points out that there are six ecological factors including population density, bird species and number, water quality level, richness degree of food and average temperature in January. Finally,the paper sets up the judgement formula of wetland class and the evaluation and judgement model of ecological environment about wetlands in Henan. |
