摘要
明晰区域生态系统服务变化及权衡/协同关系,对优化西南喀斯特生态脆弱区生态管理、攻克贫困、维护社会和谐有重要意义.以中国知网、谷歌学术和Science Direct为数据源,共检索整理89篇论文,研究结果说明:(1)从文献年代分布来看,2008-2018年间研究较少,在2019-2023年间激增.从研究区分布来看,贵州省最多,广西壮族自治区最少.(2)生态系统服务评估类型的选择不均衡且评估方法依赖于模型.(3)分析权衡/协同的研究方法机理与应用,主要分为统计分析、制图叠加分析和情景模拟分析法三类.(4)自然地理、社会经济发展和生态工程是影响权衡/协同关系的驱动因素,而自然地理为主导因子.最后,本文针对目前喀斯特区生态服务功能与权衡/协同研究不足进行了归纳总结,并提出未来研究展望.
Abstract
Stone desertification is one of the biggest ecological and environmental challenges in karst regions of southwestern China.To alleviate ecological degradation,improve regional poverty,and enhance human well-being in these karst regions,the Chinese government has im-plemented the Project of Rocky Desertification Control since the early 21st century.Evaluation of trade-offs and synergies of ecosystem services in this region is important for optimizing of ecological protection measures.Based on databases of CNKI,Google Scholar,Science Direct,etc,we collected and analyzed a total of 89 published papers about ecosystem service in karst regions of southwestern China.The results showed that:(1)In terms of the chronological distri-bution of the literature,the number of studies was small during the period of 2008-2018 and surged during the period of 2019-2023.In terms of the study area,the most of studies were conducted in Guizhou province,while a few studies in Guangxi Zhuang Autonomous Region.(2)Most of ecosystem services in these papers focused on supply,support,and regulation ser-vices,while cultural services was neglected and less selected.And the ecosystem service assess-ment mainly depended on models analysis.(3)Main methods,such as statistical analysis,carto-graphic overlay and scenario simulation were used to reveal the mechanism of trade-offs/syner-gies of ecosystem services.(4)The key driving factors of trade-offs/synergies between ecosys-tem services fall into three categories:natural conditions,socio-economic development,and ecological engineering.Wherein,natural conditions is the dominant factor.Finally,we summa-rized the shortcomings of the research on trade-offs/synergies of ecosystem services in karst re-gion,and prospected the future research in three aspects:spatiotemporal evolution,driving mechanism and ecological management,which may provide a scientific reference for the en-hancement,management and sustainable development of ecological services in the karst ecolog-ically fragile areas,in southwest China.
