A COMPLEX MODEL FOR ENVIRONMENTAL QUALIFYING AND FORECAST: CMEQ

Abstract

A quantitative characterization of the environmental situation provides important infor- mation whenever a judgement of the environment's quality is formed or investments are planned or decisions are to be supported. Such a quantitative qualification of the environ- ment may play an important role even on a regional scale when forming an opinion on the quality of the given region's environment or preparing regional strategies for environment protection or signing pacts for regional protection of the environment. The model and numerical examples to be shown in this paper describe the environment of a minor region by a parameter system of water, air, and soil quality. It is a task of the future to include ecological (biological) and social (economic) components into the model. In such a way, the model is an approximative measure of the environment's state, comparing the latter with computed quality categories, i. e., classifying the given state. If any of the quality parameters changes (e. g., the NOx emission of a country is reduced), the environment's quality changes as well and the numerical value of this change can be expressed by the model.
