摘要
作为高山淡水生态系统主要载体,高山湖泊生态系统具有生态环境原始、环境承载力低、自净能力弱以及生物群落结构单一等特点,对于气候与环境变化响应敏感。围绕气候变化背景下高山湖泊生态系统结构与功能变化这一主线,系统分析了山区海拔依赖性增暖对高山湖泊热力特性、溶解氧分层以及生物过程的影响,阐述了辐射增强背景下高山水生生物适应对策及水下辐射特征变化,揭示山区降水变化对高山湖泊跨生态系统物质补贴及生物地球化学循环的影响机制。在今后研究中,需完善多气候因子变化下的湖泊生境综合响应实验,建立对高山湖泊生态系统全要素的系统监测与整合,以加强高山湖泊生态系统对气候变化的响应过程及适应机制的认知。
As the main carrier of alpine freshwater ecosystems,alpine lakes are currently experiencing rapid climate change that has profound and complex effects on their ecosystems.In this study,we systematically analyze the effects of altitude-dependent warming on the thermal properties,dissolved oxygen stratification,and biological processes of alpine lakes in the context of climate change,describe the adaptation measures of alpine aquatic organisms and changes in underwater radiation characteristics in the context of radiation enhancement,and reveal the effects of precipitation changes on the cross-ecosystem material subsidies and biogeochemical cycles in alpine lakes,as well as the mechanism of the impact of precipitation changes on these cross-ecosystem material subsidies and biogeochemical cycles in mountain lakes.In the future research,we must improve the integrated response experiments of lake habitats under the changes of multiple climate factors,strengthen the systematic monitoring and integration of the whole elements of alpine lake ecosystems,and change the research type(i.e.,static and qualitative research to process,dynamic,and quantitative research)to enhance knowledge on the response mechanism of alpine lake ecosystems to global climate change.
