Introduction:Adaptation and mitigation are two main approaches to combating climate *** is considered as the most important tasks in dealing with climate change in scientific res earch,financial support and technical practices as global warming intensifes;while currently the warming trend still cannot be reversed,and adaptation task seemed to gain urgency although it is *** synergies and tradeoffs of these two strategies revealed increasingly importance on reduding adverse dimate *** on synergistic relationships has developed from definition and feasible analysis,to the development of quantitative tools and exploration in practice and application,though the latter aspect is still in its initial ***/*** review shows that the traits of mitigation and adaptation,the difer-ences and similarities between them,then ilustrate the significance and mechanism of their synergies and *** it is explained that methods and applications of single and integrated models,and cost-effectiveness ***/Conclusion:We hold the opinion that the future research and applications should be enhanced in terms of four aspects:reinforcement of interrelations and common mecha nisms between mitigation and adaptation actions study;building and improving the monitoring and evaluating systems;promoting departmental and regional scale investiga-tions and applications;and establishing policy and security systems.

Spatial-temporal heterogeneity of ecological quality changes across the Qinghai-Tibet Plateau under the influence of climate factors and human activities

Research in Cold and Arid Regions 2024年第3期16卷 129-140页

Over the last few decades,the ecological quality of the Qinghai–Tibet Plateau(QTP)has significantly changed due to climate warming,humidification,and increasing human ***,evaluating this region's ecological quality and dominant factors is crucial for sustainable *** this study,the changes in the ecological quality on the QTP from 2000 to 2020 were evaluated based on aggregated indices and Sen–MK trend analyses,and the dominant factors affecting the ecological quality of the QTP were quantitatively analyzed using decision tree *** results revealed that(1)the ecological quality of the QTP exhibited an overall high trend in the east and a low pattern in the west;(2)the ecological quality of the QTP significantly increased from 2000 to 2020,and human activities were the dominant factors causing this change;and(3)the changes in the ecological quality and dominant factors exhibited obvious spatiotemporal *** area with an improved ecological quality occurred mainly in the northern QTP *** was governed by human activities and *** contrast,the area with a deteriorated ecological quality occurred largely in the southern QTP region and was dominated by human activities and *** 2000–2010 period was the most significant period of heterogeneity regarding of ecological quality and its driving factors.(4)The change in the ecological quality was mainly affected by the synergistic relationship between human activities and climate change in this region,which encompassed multiple dominant *** study provides important information on the spatiotemporal heterogeneity of ecological quality change and its dominant factors on the QTP and offers systematic guidance for the planning and implementation of ecological protection projects.
