摘    要:在GIS和RS技术支持下,以遥感数据和土地利用数据为基础,以行政区划为评价单元,构建景观生态风险评价模型,定量评价了研究区内景观生态风险的时空动态变化特征。结果表明,较低风险区主要分布于以苕溪为主的山地丘陵区,中等风险区主要分布于农业发达的平原区,较高风险区及高风险区主要集中于沿湖经济发达区。

关 键 词:景观  生态风险评价  太湖流域

Abstract:The research took the quantitative analysis of spatio-temporal dynamics character of ecological landscape risk variation in Taihu Lake by using GIS and RS technologies, based on the remote sensing and land use data. The risk assessment model took the administrative division as the assessment unit. The model comprising a landscape disturbance index and a land use sensitivity index was established on the based of landscape perspective. The results showed that the low risk areas were mainly in the hilly and mountainous regions, while the medium risk areas were mainly in the developed agricultural plainregions. The higher and highest risk areas distributed at the economically developed regions around the lake.
Keywords:landscape  ecological risk assessment  Taihu Lake basin
