【摘要】 自国家提出构建山水林田湖草生命共同体以来,已启动第三批山水林田湖草生态保护修复工程试点申报,但一些工程设计缺乏整体性,造成"真破坏"和"伪生态"的现象时有发生。本研究以石川河综合整治项目为例,针对石川河乱采乱挖河道砂石,工业污染,附近村民焚烧垃圾造成气、水和土污染极其严重,生态、人居环境持续恶化,鱼虾绝迹,污水横流,垃圾成堆等问题,采用重建生态河道、恢复生态、景观重塑、土地平整、PE复合土工膜、土壤修复等技术构建山水林田湖草生命共同体,并分析了生态、经济和社会效益,通过项目实施,为石川河流域提供了洁净的土壤环境、稳定的土体结构,有效改善了生态环境,提高了生活质量,实现生产发展、生态良好,不断满足社会发展建设美丽乡村的需要,同时为构建流域山水林田湖草生命共同体提供理论依据和实践支撑。更多还原

【Abstract】 Since China proposed the construction of the "mountains-rivers-forests-farmlandslakes-grasslands"community of shared life,the third batch of ecological protection and restoration project has been launched. However,some engineering designs lack integrity,resulting in"true destruction"and"pseudo-ecology"phenomena. Taking the Shichuan River comprehensive improvement project as an example,this study focused on the environmental problems,including the excavation of river sand and gravel in the Shichuan River,industrial pollution,and the pollution of gas,water and soil caused by the burning of garbage by the nearby villagers. The ecological and living environment continued to deteriorate,and the fish and shrimp gone extinction,polluted water and garbage were widely distributed. The techniques of reconstructing ecological river channels,restoring ecology,reshaping landscape,land leveling,PE composite geomembrane,and soil remediation were applied to construct a community of shared life. We also analyzed the ecological,economic and social benefits. The implementation of the project provided clean soil and stable soil structure for the Shichuan River,effectively improved the environment,enhanced the quality of life,achieved production development and good ecology,and continuously met the needs of social development and construction of beautiful villages. It provided theoretical basis and practical support for constructing the watershed-level community of shared life.更多还原
