摘要/Abstract

摘要：

以成都市锦江流域典型河段柏条河–府河为研究对象, 从河流健康内涵出发, 选取生境特征、生物群落和社会服务三方面共16个指标, 建立满足河流生态系统完整性和社会服务功能的河流健康评价指标体系, 采用实地勘查、遥感、GIS和环境DNA等方法来定量化指标, 通过综合评价法分4个河段进行河流健康评价。结果表明, 各评价河段的河流健康评价指数范围为3.23~3.82, 处于亚健康水平。河流健康评价指数呈现从上游到下游沿程降低的趋势, 不同河段河流健康水平表现出的强空间异质性与人类活动相关。研究结果可为成都平原河流的可持续管理提供科学依据, 也为其他受人类活动影响的河流系统的健康评价提供方法。

Abstract:

The Baitiao-Fu River, a typical tributary of Jinjiang River in Chengdu City of China, was selected to perform the health assessment based on ecological integrity and social service functions. Therein, 16 specific indicators from three aspects including habitat characteristics, biological community and social service were selected to establish a river health assessment system for meeting the needs of river ecosystem integrity and human services. Field investigation, remote sensing and GIS, environmental DNA, and statistical method were used to quantify these indicators, and the comprehensive assessment method was applied to four river segments to calculate the river health assessment index (RHI). The results showed that all RHIs of these tributaries ranged from 3.23 to 3.82, suggesting the sub-healthy level. The river health status was generally good in the upper reaches, whereas that was relatively poor in the middle and lower reaches, which presented strong spatial heterogeneity, and reflected that the health of river system might be affected by human activities. The results provide a scientific basis for the sustainable management of rivers in Chengdu Plain, and contribute a method for health assessment of river ecosystems affected by human activities.
