浙江省钱塘江源区域山水林田湖草生命共同体健康评价

[目的]分析浙江省钱塘江源区域山水林田湖草生命共同体健康状况，为国土空间规划和生态管理提供科学参考。[方法]基于生命共同体理论与活力—组织力—恢复力(vitality-organization-resilience, VOR)生态模型理论，构建生命共同体健康评价指标体系。利用3S技术和社会经济统计资料，以县域为评价单元，对钱江源区域山水林田湖草生命共同体的健康状况进行评价和分级。[结果](1)2020年，钱江源区域的淳安县处于生命共同体健康状态，建德市、开化县、常山县生命共同体均为亚健康状态。(2)2015—2020年4个县(市)生命共同体健康指数总体呈上升趋势，健康指数上升趋势大小依次为：建德市>常山县>淳安县>开化县。(3)2020年，4县(市)中山水林田湖草子系统健康状态最好的为常山县，最差的为淳安县；生态系统健康状态最好的为淳安县，最差的为常山县。(4)钱江源区域林、田子系统结构及其生态服务功能有待提升优化。(5)生态修复试点工程对于提升钱江源区域生命共同体健康状态在一定程度上起到了积极的推动作用。[结论]钱江源区域山水林田湖草生态修复工程取得了阶段性成果。4...

Health Evaluation of Life Communities of Mountains-Rivers-Forests-Farmlands- Lakes-Grasslands in Source Area of Qiantang River in Zhejiang Province

[Objective] The health status of the living community of mountains-rivers-forests-farmlands-lakes-grasslands in source area of Qiantang River of Zhejiang Province were analyzed in order to provide scientific reference for land spatial planning and ecological management.[Methods] Based on life community theory and VOR (vitality-organization-resilience) ecological model theory, a health evaluation index system of life communities was constructed. Using 3S technologies and socioeconomic statistics, the health status of the life community in the Qiantang River source area was evaluated and graded (with the county as the evaluation unit).[Results] ① The life community health index of Chunan County in 2020 was classified as healthy, but the life community health indexes of Jiande City, Kaihua County, and Changshan County were classified as sub-healthy. ② From 2015 to 2020, the overall life community health index of the Qiantang River source area showed an upward trend, and the upward trend decreased in the following order:Jiande>Changshan>Chun''an>Kaihua. ③ Among the four counties (cities) in the Qiantang River source area in 2020, Changshan County had the best health status for the mountains-rivers-forests-farmlands-lakes-grasslands subsystem, while Chun''an County had the worst health status. Chun''an County had the best health status for the ecosystem subsystem, while Changshan County had the worst health status. ④ The structure and ecological service function of the forests and farmlands subsystems in the Qiantang River source area needs to be improved and optimized. ⑤ The ecological restoration pilot project in the Qiantang River source area had played a positive role in improving the health status of the life community to some degree.[Conclusion] The ecological restoration pilot project of mountains-rivers-forests-farmlands-lakes-grasslands in the Qiantang River source area has achieved various stages of results. The four counties (cities) should next carry out relevant restoration work to address the different problems of the mountains, rivers, forests, farmlands, and lakes subsystems. At the same time, governments should carry out comprehensive planning and ecological renovation in order to achieve more scientifically integrated governance, health management, and sustainable management for the mountains-rivers-forests-farmlands-lakes-grasslands community system.
