Application of Fuzzy Matter-element Model Based on Coefficients of Entropy in Ecosystem Health Evaluation of Yellow River Delta
In order to reflect the situation of the sustainable development in the Yellow River Delta area, this paper constructs ecosystem health evaluation framework based on fuzzy matter-element method of entropy weight on the basis of PSR (pressure-state -response) model to evaluate the ecosystem health from the aspects of regional economic development, water and sediment conditions and ecological environment. Twelve evaluation factors are adopted and the theory of information entropy is applied to determine the weights of the evaluation factors, including the use of remote sensing technology on the part of the evaluation factor for quantitative analysis. The results show that the ecosystem health status in Yellow River Delta area in three periods ( 1996, 2000, and 2004) was different, and its status of 1996 was the best, and the worst was in 2000, and the ecosystem health status of 2004 became better than that of 2000.
