中文摘要:
      滦河流域是我国重要生态保障地区,亟需开展水生态承载力评估,识别承载力限制因素,以指导流域生态文明建设。针对滦河流域水资源矛盾突出、水生态系统服务功能退化等问题,采用WaREES框架从“水资源-水环境-水生态-水安全”4个维度构建承载力评估和指标贡献量化方法,对滦河流域进行水生态承载力评估研究。结果表明:滦河流域水生态承载力指数(HECCI)介于43.8~53.8之间,总体呈临界超载状态;水环境呈安全承载状态(均分为61.3),水安全和水生态均为临界超载状态,而水资源呈超载状态(均分为22.9);水资源禀赋弱和开发强度大是限制流域承载力的关键短板,水资源禀赋和水资源利用指数对流域HECCI的贡献率分别为6.4%和5.5%;水生生境质量、生物完整性和水文调节功能是水生态和水安全临界承载的主要控制因素。提出的水生态承载力评估技术方法具有科学性和实用性,对流域/区域水生态环境管理具有参考价值。
英文摘要:
      The Luanhe River Basin is an important ecological security area in China. It is urgent to carry out assessment of water ecological carrying capacity and identify the limiting factors of bearing capacity to guide the construction of ecological civilization in the basin. Based on the integrity of water ecosystem service function, this paper constructs the capacity assessment and indicator contribution quantification method from the four dimensions of “water resources-water environment-water ecology-water safety” using the WaREES framework, and carries out the application of Luanhe River Basin assessment based on the survey. The results show that the hydro-ecological carrying capacity index(HECCI) of the Luanhe River Basin is between 43.8 and 53.8, indicating the overall a critical overload situation. The special assessment showed that the water environment was in a safely loaded state (61.3), both water safety and water ecology were critically overloaded, while water resources were overloaded (22.9). The weak endowment of water resources and the high development intensity are the key shortcomings that limit the carrying capacity of the basin. The contribution rates of water resources endowment and water use index to the basin HECCI are 6.4% and 5.5%, respectively. Aquatic habitat quality, biological integrity and hydrological regulation are the main controlling factors for the critical carrying of water ecology and water safety. The proposed water ecological capacity assessment technology method is scientific and practical, and has reference value for watershed/regional water ecological environment management.
