基于模糊多准则的矿山生态环境影响研究

Study on the ecological environment in mines by fuzzy multiple criteria principle

矿产开发活动既产生大量的物质财富,也直接地影响生态平衡;其对生态环境的影响程度极其复杂,并且具有随机性和模糊性。文中基于模糊多准则基本原理,用梯形模糊值表示影响和制约矿山生态环境的主要因素指标,确定方案-属性之间的模糊指标值和属性-属性之间的模糊权值,计算各方案的模糊效用度,并对其比较、排序,从而确定对矿山生态环境的影响程度,为生态矿业园的规划、实施和管理提供科学的决策依据。

Abstract： Mining engineering exerts a large quantity of material wealth, also directly affect the ecosystem equilibrium. While, its influence degree on ecological environment is very complicated, and with characteristics of randomicity and fuzzification. With the principle of fuzzy multiple criteria, the primary factors that influence and control the ecological environment in mines, are expressed with trapezoid fuzzy numbers. With an approach to handle fuzzy weighting, the fuzzy utility degree of every plan are calculated to set decision making fuzzy utility degree in conditions of different confidence levels. By comparison and ranking of fuzzy utility degree, a comprehensive, reasonable and scientific basis for programming, actualizing and managing future mine bionomics garden is provided.
