摘　　要：生态调节服务产品是生态产品总值(GEP)核算的重要组成部分。探究生态调节服务产品价值变化趋势及驱动因素有助于指导GEP提升。文章分析了2011—2021年汉中市调节服务价值变化的驱动机制。结果表明:2021年汉中市调节服务价值为1794.66亿元,其中水源涵养、土壤保持、洪水调蓄、固碳和气候调节合计占比99.9%;2011—2021年,汉中市调节服务价值增加了92.69亿元;自然生态系统面积变化、海拔、植被净初级生产力(NPP)变化是驱动调节服务价值变化的主要因素,能够解释87.9%的价值变化,森林面积和NPP的提升促进了调节服务价值的提高。建议未来积极开展生态保护和修复,提升自然生态系统面积和质量,确保调节服务价值的提升,同时探索生态产品价值实现机制,促进绿水青山向金山银山的转化。The value of ecosystem regulating products is the main component of Gross Ecosystem Product(GEP)accounting.Exploring the trends and driving factors of GEP dynamics can guide the enhancement of GEP.The value change in ecosystem regulation products and their driving factors were analyzed in Hanzhong from 2011 to 2021.The results showed that the value of ecosystem regulating products in Hanzhong in 2021 was 179.464 billion yuan,with water retention,soil retention,flood mitigation,carbon sequestration,and climate regulation accounting for 99.9%of the total value.From 2011 to 2021,the value of ecosystem regulating products in Hanzhong increased by 9.269 billion yuan.Changes in the area of natural ecosystem,altitude,and change of net primary productivity(NPP)were the major driving factors.These explained 87.9%of the value change.The improvement in forest area and NPP positively promoted the value of regulating services.It is recommended to actively implement ecological protection and restoration project in the future,improve the area and quality of natural ecosystems,ensure the enhancement of regulation service value,and explore mechanisms for value realization of ecological products.These measures will promote the transformation from“lucid waters and lush mountains”to“invaluable assets”.
