社会生态系统视角下的广西河道管护效果评价OA

To understand the current state of river management and protection in Guangxi and evaluate whether the existing measures can meet the requirements for the construction of"Happy Rivers",an evaluation of river manage-ment and protection effectiveness in Guangxi was conducted.A total of 149 river sections in Guangxi were selected as the research objects,and a social-ecological system evaluation framework for river management and protection in Guangxi was established.The indicator scores were determined through a combination of objective assignment and expert scoring.A new method combining the entropy weight method and ICC was innovatively adopted to determine indicator weights.The performance of the river management and protection subsystems in Guangxi was analyzed,and the overall effectiveness of river management and protection was calculated using the TOPSIS method.The re-sults show that most rivers in Guangxi are managed through non-professional approaches,either assisted by public welfare positions or spontaneously maintained by social groups,resulting in moderate management effectiveness and low coupling coordination degree.The governance system is the disadvantaged subsystem under most conditions,while the resource system is the advantageous subsystem,indicating that the governance efficacy of Guangxi's rivers lags behind the resource endowment.Under the public-welfare-position-assisted management model,township-level and village-level river sections achieved a moderate degree of coupling coordination,implying that through op-timizing the organizational management of public welfare positions,the natural endowments of the resource system can be made full use to achieve low-cost and highly coordinated river management and protection in rural areas.
