中国省级层面生态保护领域适应气候变化对策、行动与措施评价OA

Systematically assessing the countermeasures and actions for adapting to climate change in the field of local ecological protection is of great significance for the scientific implementation of adaptation actions.This study collected 742 documents related to climate change(CC)adaptation in the field of ecological protection at the provincial-level in China(excluding Taiwan province),and drew on international analytical methods to identify the status of CC adaptation countermeasures and actions at the provincial level.It also analyzed the adaptation initiatives index score,as well as the scores of adaptive capacity and adaptation readiness.In addition,by calculating Kendall's tau-b,spearman-rho,and Pearson correlation coefficients,the relationships between the adaptation initiatives index and adaptive capacity and adaptation readiness were identified.The results show:(1)the provincial countermeasures for CC adaptation in the ecological protection field in China mainly focus on formulating and implementing regulations and economic incentive strategies related to ecological protection,ecosystem management and protection,biodiversity conservation and utilization,prevention of ecological disasters and harmful organisms,ecological degradation control and ecological monitoring,ecological space optimization,development of adaptive technologies,implementation of comprehensive ecological protection countermeasures and supervision.(2)The adaptation to CC in the field of ecological protection involves 6 types of actions and 31 specific measures,including early warning of extreme events and related disasters,disaster prevention and mitigation,emergency response,ecological protection and restoration,biodiversity conservation,ecological monitoring and supervision,ecological space zoning and optimization,and capacity building,etc.(3)The adaptation measures in the field of ecological protection in response to CC mainly belong to responsive actions,including the no-regret strategy,the low-regret strategy,the win-win strategy,the flexible adaptability strategy,as well as response-oriented measures in response to CC.Moreover,measures for risk prevention,reducing vulnerability,increasing resilience,and improving adaptive capacity are also included.(4)The score of the adaptation initiatives index in the field of ecological protection belongs to medium level(the provincial total scores range from 8.5 to 14.0).(5)The scores of adaptive capacity and adaptation readiness both belong to medium level(the scores are 2.5-4.0 and 3.0-5.5 respectively).(6)The adaptation initiatives index shows a significant positive correlation(P＜0.05)with adaptive capacity and adaptation readiness.The results indicate that the countermeasures and actions for CC adaptation in the provincial-level ecological protection field in China have increased,but they are mainly focused on responding to current ecosystem changes,and mainly include no-regret and low-regret adaptive actions.Specialized measures for CC response,adaptive capacity and adaptation readiness still need to be increased.
