Abstract :
Based on the evaluation of the ecological environment quality in ore concentrated area, combining with the pollution sources and composing characteristics, the environment quality grey early-warning system in ore concentrated area is established in this article. Because of the diversity, complexity, and particularity of the pollution sources in ore concentrated area, the composition of the environment quality early-warning grey index system in ore concentrated area because the key part to establish the early-warning system. The grey model is used to simulate and predict the quality of the ecological environment in ore concentrated area, and the early-warning indexes are selected based on the sustainable development index system and the regional ecological environmental quality grading method of the United Nations Commission for Sustainable Development (CSD), and the early-warning index system including single indexes and comprehensive indexes based on the sustainable development could not only fulfill the requirements of the data and the high prediction precision, but also have more practical values in management and practice on macro layer and micro layer.
