基于多目标空间分析的危险废物决策支持模型研究

我国日益增长的危险废物对于环境安全和人体健康都构成极大威胁,如何高效、科学的对危险废物从产生到最终处置的全过程进行管理和决策是我国危险废物管理工作面临的重要问题。区域危险废物的管理和环境风险控制是一个涉及到废物特性、自然环境和社会经济等诸多因素的综合决策过程。文章通过综合考虑危险废物处理处置过程中的环境影响因素、经济因素和环境风险因素,结合空间分析技术和多目标决策的方法,设计了一个危险废物多目标空间决策支持模型,并以广州为例进行了模拟应用。危险废物管理的决策者根据不同的侧重点,通过本模型在备选废物处理处置中心中确定建设地点,同时能够使用本模型选择危险废物的最佳运输路径。本模型为危险废物管理和决策支持提供了一种直观、科学和实用的支持,具有一定的理论和现实意义。

Regional Hazardous Waste Decision Support Model Based on Multi-objective Spatial Analysis

Hazardous waste is a great threat to environment safety and human health. How to scientifically and efficiently manage whole process of hazardous waste is very important. Regional hazardous waste management and environmental risk control is a complicated process which are related to characteristics of waste as well as factors of environment,economy and society. Based on comprehensive consideration of environmental risks,environmental factors and economic factors,combined with spatial analysis and multi-objective decision making method,a multi-objective spatial analysis model of hazardous waste was established. Taking Guangzhou as an example for simulation,with the model,decision makers can decide the construction location among the optional treatment and disposal centers,select the optimal hazardous waste transportation path according to different emphasis points. The model will provide the visual,scientific and efficient support for regional hazardous waste management and decision-making,which has a certain degree of theoretical and practical significance.
