区域生态风险识别系统构建

摘要

由于区域生态环境的复杂性,导致区域生态风险识别与评价较为困难,在Relative Risk Model基础上,构建了区域生态风险识别的概念模型,并编制了风险识别的软件系统.研究以生态风险评价理论为基础,从风险路径着手构建识别系统.运用该系统对东太湖地区进行生态风险分析的结果表明:系统能够较好的反映该地区主要的生态风险实际情况,能够让环境管理者对区域的风险源、风险因子、评价终点所受风险做出合理的判断,并作出合理决策.%Because of the complexity in regional eeo-environment, it's difficult to identify and assess the ecological risks in the certain area.Based on the relative risk model theory, the study constructs the idea model to distinguish the potential risks on the regional scale.The software system has been developed at same time, which is based on the theory of assessment on regional ecological risks and identification of risk mutes.Used in Eastern Tai Lake, the system draws the conclusions and demonstrates that it can work properly to reveal ecological risk situation in the area.The environment manager could make reasonable judgement on the risk sources, risk factors and assessment endpoints by the model and make scientific decisions.The system is proved to be a good tool to serve for the management of environment.
