千岛湖区域生态风险评价研究

随着区域经济特别是旅游开发活动的升温,千岛湖流域正面临着开发过程中不断增强的人为活动的影响.客观科学地评价由此所带来的生态风险问题,是指导干岛湖区域经济与生态环境协调发展的理论基础.本研究以生态风险评价基本理论为指导,在环境现状评价的基础上,对近10年来的常规监测数据、酸雨、底泥进行了系统分析,构建了水域生态风险胁迫因子总氮和总磷的预测模型,最后从风险管理对策和风险管理技术两方面提出千岛湖区域生态风险管理体系.

The Ecological Risk Assessment of Qiandao Lake Area

With the increased regional economic development, especially tourism development, Qiandao Lake is facing more and more severe threats from human activities. It is of great importance to assess the emerging ecological risk in Qiandao Lake so that the regional economy and ecological environment can co-develop in a harmonious manner. Under the direction of relevant ecological risk assessment theories, this study: assesses the current environmental situation of Qiandao Lake; makes a systematic data analysis of the water quality, acid rain and bottom mud in recent ten years; constructs the mathematical forecasting models of the ecological risk stress factors TN and TP; brings forward the ecological risk management system, specifically risk management countermeasures and risk management technologies.
