摘要

为系统科学评估海南流域的水生态现状,本研究以海南岛为例,进行了热带岛屿流域水生态评价理论研究和实践.研究基于相关成果和流域突出水生态问题,构建了水生生物、水生境、水环境和水资源共11项指标的评价体系,综合利用专家打分和层次分析法计算了评价指标权重,并采用水生态环境质量综合评价指数(WEQI)对南渡江、昌化江和万泉河等海南岛典型流域开展水生态现状评价实践.结果表明:南渡江、昌化江和万泉河干流水生态为良好水平(63.77~71.57分),4座水库为一般水平(41.50~59.55分),水生生物是水生态提升的首要制约项,人为活动是水生态破坏的主要原因,水库还受生态需水量的限制.本研究构建的热带岛屿水生态评价体系可为当地水生态监测和评价提供科学依据.

Abstract

A theoretical and practical approach was taken to systematically and scientifically assess the current water ecology status in the watersheds of Hainan Province, using Hainan Island as an example of tropical island watersheds. An assessment system consisting of 11indicators for aquatic organisms, water habitats, water environment, and water resources was constructed based on relevant results and outstanding issues in the watershed. The assessment factors were weighted by expert scoring and hierarchical analysis, with the Water Eco-environment Quality Index (WEQI) used to evaluate the ecological status of typical watersheds in Nandu River, Changhua River, and Wanquan River on Hainan Island. Results indicate that dry streams in these rivers have good water ecology levels (63.77~71.57points), while reservoirs are at an average level (41.50~59.55points). Aquatic organisms remain a primary constraint to improving water ecology; human activities are identified as the main cause of damage; reservoirs also face limitations due to ecological water demand. Overall, this study's tropical island water ecology assessment system is accurate and applicable for providing scientific basis for local monitoring and assessment.
