Optimization of environmental monitoring sites by optimal index method

The given paper introduces in detail the principles and the calculation procedures of the optimal index method and uses the method to optimize the atmospheric environmental monitoring sites. As is known, the optimal index method is a decision-making means derived from the Technology for Order Preference by Similarity to Ideal Solution, which can be used for the optimization of environmental monitoring sites, a powerful means to control the environmental qualities in one. Therefore, the optimal index method is of great scientific as well as practical significance to obtain the optimal monitoring sites in the field of environmental protection. In this article, we choose the concentration of three atmospheric pollutants SO_2, NO_x and TSP as evaluation indexes. On the basis of analyzing the actual monitoring data of atmospheric pollutants, the author has categorized the ranks of monitoring sites in the light of size, and at the same time established the optimal model of environmental monitoring sites in Zhengzhou city. The optimal results of 17 atmospheric environmental monitoring sites with the optimal index method show that the optimization sites can basically reflect the general status of air quality in Zhengzhou city, and therefore embody the purpose of optimal number of sites. Hence, there is no doubt that our newly improved methods will have a great reference value to the optimization of monitoring some definite environmental sites.
