QUANTITATIVE STUDY ON ECO-ENVIRONMENTAL CONTROL OF ARID LAND, WESTERN CHINA

Adopting optimum control and scientific management of eco environment is very important to protecting eco environment against disruption and promoting the coordinated growth of soc economy system and eco environment system and building a harmonious relationship between human behavior and natural world, especially in the arid land, western China. At present, quantitative index system of eco environment is usually looked upon evaluation index system of eco environmental quality. These indexes, such as, water environment index, soil environment index, atmosphere environment index and so on, are mainly used to evaluate eco environmental quality. However, in order to study control and management of eco environment, the artificial factors must be taken into account, because the behavior of control and management of eco environment is controlled by human being. So, both the indexes of eco environmental quality and the indexes of soc economical behavior should be considered together. This paper, according to the characteristics of arid land eco environment, from the point of quantitative study on eco environmental control and management, puts forward a new quantitative index system including evaluation index group of eco environmental quality and control index group of soc economical development.Furthermore, this paper introduces a new quantitative study method, including index system, optimum control model, and control and management scheme selection and its actions.
