摘要: 针对流域重金属生态风险评价缺乏实时、有效的方法和监测技术的现状,利用遥感和气象数据构建合理、准确的评估模型监控决策流域环境状况,采集和收集研究区域流域内的气象遥感以及土壤重金属数据,并结合Hakanson潜在生态风险指数,构建流域重金属生态风险评估系统模型。运用Microsoft Visual Studio 2013、ArcGIS等开发平台以及WebGIS技术完成B/S架构系统开发,实现对流域生态环境的远程评估管理。应用结果表明,该系统实现了研究区域重金属含量分析、生态风险等级划分及评价等功能,能够提高研究区生态风险评价的实时性和数据积累结果分析的准确性。

Abstract: In view of the lack of real-time and efficient method and monitoring technology for watershed heavy metal ecological risk assessment,this paper uses remote sensing and meteorological data to construct a reasonable and accurate evaluation model to monitor the environmental conditions of the decision basin.By collecting meteorological remote sensing and soil heavy metal data in the study area and combining the Hakanson potential ecological risk index,this paper proposes an Ecological Risk Assessment (ERA) model for watershed heavy metals.Using Microsoft Visual Studio 2013,ArcGIS and other development platforms and WebGIS technology to jointly complete the B/S architecture system development,this paper achieves remote assessment management of the watershed ecological environment.The application results show that the system realizes the functions of heavy metal content analysis,ecological risk classification and evaluation in the study area and increases the real-time performance of the ecological risk assessment of the study area and the accuracy of the data accumulation result analysis.

Key words: Geographic Information System(GIS), heavy metal, watershed ecology, risk assessment, ERA model
