Risk Analysis of Ecological Environment Healthy

Abstract:

The risk analysis of ecological environment healthy is limited by multi-factors, high dimensional data, small samples and incomplete information. This paper develops a method of risk analysis model of ecological environment, which is combined with the combination with projection pursuit method and the information diffusion theory. This model spreads the risk information of the actual observation data to the properties of the risk threshold in order to explore the nonlinear relationship between them and calculates the risk probability of the whole ecological environment. This paper takes 35 cities as study objects, evaluates the risk grade of ecological environment of each city and estimates the comprehensive risk probability of ecological environment healthy in China. The research result shows: most of those cities are in the "less safety" risk grade and "unsafety" risk grade. And the whole ecological environment healthy is in high-risk and shows the unstable condition.
