基于河岸带植物多样性的河流健康评价——以柏条河－府河河段为例

Assessment of River Health on the Basis of Riparian Plant Diversity——Taking the Baitiao-fu River as an Example

摘要: 基于河流健康评价目的,将柏条河-府河河段划分为上游、中游、下游3个区域针对河岸带植物多样性进行多层次调查。在多个指标构建的评价系统中对各河段进行评分,上游、中游和下游河段得分分别为72.7分、59.1分和59.3分。评分结果直观反映出柏条河-府河不同河段河岸带植物多样性的状况。依据调查结果为各河段维持和提升植物多样性、河流健康提出了管理措施与建议。

Abstract: Investigations were made on the riparian plant diversity in the upper reaches, middle reaches and lower reaches of the Baitiao-fu River at different levels for the purpose of estimating river health. Each reach was scored according to the evaluation system which consists of several indexes. The scores of upper,middle and lower reaches were 72.7, 59.1 and 59.3 respectively. The result reflected the riparian plant diversity state of each reach of Baitiao-Fu River directly and accurately. According to the survey and analysis results, management measures and recommendations were proposed for each reach to maintain and promote the plant diversity and river health.
