青海高原国土空间生态保护修复工程气候变化压力分析

气候变化是青海高原国土空间生态保护修复工作面临的主要压力之一,然而目前鲜有对该区域生态修复工程气候变化压力的量化分析。聚焦这一问题,基于多源数据,明确1960年以来青海高原的气候变化过程,分析土地覆被类型变化的气候驱动作用,并量化未来气候变化压力。研究发现:青海高原自1960年以来经历了显著的"暖湿化"过程,并呈西部升温快于东部、冬季升温快于夏季的特点。受气候变化的影响,青海高原草地和灌木分布在1980-2020年间呈现普遍扩张趋势,西北局部呈现收缩趋势。气候预测显示,青海高原将面临持续的气候变暖压力,尤其是南部地区。研究结果可为青海高原国土空间生态保护修复工程中相关气候缓解和适应措施的制定提供数据与理论支撑。
Analysis of climate change pressures on ecological protection and restoration projects of territorial space in Qinghai Plateau
Climate change is one of the main pressures that the ecological protection and resto-ration in Qinghai Plateau continues to face,yet there is currently a lack of quantitative analysis of the climate change pressure on ecological restoration projects across this region.Focusing on this issue,this study clarified the climate change process across Qinghai Plateau since 1960,analyzed the driving effects of climate change on the changes in land cover,and quantified the projected future climate change pressures that Qinghai would face during the 21st century,based on multi-source data.We found that Qinghai Plateau has experienced significant warm-ing-wetting trends since 1960,with the change characterized by faster warming in the west than in the east and faster in winter than in summer.Affected by climate changes,the distribu-tion of grass-shrubs in the study area generally expanded from 1980 to 2020,while degraded in the northwest.Climate predictions indicate that Qinghai Plateau is likely to face profound pres-sures from continued warming trends across the 21st century,especially for the south.Our find-ings could serve as data and theoretical support for the formulation of relevant climate mitiga-tion and adaptation measures in the ecological protection and restoration projects of territorial space in the plateau.
