南湖荡滨水区生态风险评价研究

Nanhudang Ecological Risk Assessment of Urban Waterfront

以常熟市南湖荡区域为例,基于景观生态学原理,参考美国国家环保局提出的生态风险评价导则和方法,对南湖荡区域进行了系统的生态风险评价,确立污染、洪涝灾害、滨水景观破碎化为主要风险源。通过对风险区的六类景观生态系统的风险综合评价,得出南湖荡区域的综合生态风险分布,并提出了南湖荡滨水区不同风险分区的保护建议,对改善区域生态环境具有重要意义。

Taking Nanhudang area in Changshu City for an example, ecological risk assessment system is proposed by applying the principle of landscape ecology and referring the guidance for conducting ecological risk assessment issued by Environmental Protection Agency of America. The pollution, flood disaster and landscape fragmentation of waterfront are taken as the major risk source. Through the comprehensive risk assessment of six landscape ecosystems in risk area, the comprehensive risk distribution in Nanhudang area is obtained and the protection suggestions for different risk areas are proposed, which will play an important role in improving the ecological environment of Nanhudang area.
