    Ecological Protection–Restoration Practice of Mountains Rivers Forests Farmlands Lakes Grasslands Sands in the Jialu River Basin

    • 摘要: 流域生态系统是以地表水和地下水为主要纽带,具有明确边界的国土空间地理单元,是国土空间生态修复的最佳实施单元。基于流域生态恢复理论,以黄土高原地区佳芦河流域为研究对象,在全面客观了解流域生态环境现状与生态问题的基础上,按照“保持水土资源,恢复自然生态”的理念,突出水资源涵养和科学利用措施,以保水为主线的基于自然的解决方案,将流域划分为8个修复单元,实施13类工程措施,部署4个子项目,形成小流域山水林田湖草沙一体化保护和修复体系,对流域山水林田湖草沙生命共同体进行系统保护和修复。研究结果表明,开展流域山水林田湖草沙生态保护修复,有助于控制佳芦河流域及沿岸生态系统脆弱、水土流失严重、工矿与城镇水污染凸显、历史遗留矿山、农用地质量较低、生态保护和修复能力较弱等问题,有效缓解水土流失状况和减少入黄泥沙,持续提升流域生态环境质量,增强山水林田湖草沙生命共同体的稳定性,提高生态系统服务功能,筑牢中国北方生态安全屏障,对黄土高原地区流域生态保护修复具有启示意义。

       

      Abstract: Watershed ecosystem is a territorial spatial geographic unit with clear boundary, which is mainly linked by surface water and groundwater, and is the best implementation unit of territorial spatial ecological restoration. Based on the theory of watershed ecological restoration, taking the Jialu River basin in the Loess Plateau as the research object, on the basis of a comprehensive and objective understanding of the current situation and ecological problems of the watershed ecological environment, and in accordance with the concept of "conserving water and soil resources and restoring natural ecology", the watershed is divided into 8 restoration units, and 13 types of engineering measures are implemented, 4 subprojects will be deployed to form an integrated protection and restoration system for small watershed landscapes, forests, fields, lakes, grass and sand, and systematically protect and restore the life community of watershed landscapes, forests, fields, lakes, grass and sand. The research results show that the ecological protection and restoration of mountains, rivers, forests, fields, lakes, grass and sand in the basin will help to control the fragile ecosystem, serious water and soil loss, prominent water pollution in industrial and mining areas and cities, mines left over from history, low quality of agricultural land, weak ecological protection and restoration capacity in the Jialu River basin and its coastal areas, effectively alleviate the situation of water and soil loss, reduce sediment inflow into the Yellow River, and continuously improve the quality of the ecological environment in the basin, To enhance the stability of the life community of mountains, rivers, forests, fields, lakes, grass and sand, improve the ecosystem service function, and build the ecological security barrier in the north of China are of great significance for the ecological protection and restoration of the watershed in the Loess Plateau.
