Research and prospects on ecosystem services and trade-offs/syner-gies relationships in the karst regions of southwestern China
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.
