浙江省钱塘江源区域山水林田湖草生命共同体健康评价OA北大核心CSTPCD

[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.
