摘要
针对我国西南喀斯特地区生态环境演变历史及新的形势下面临的挑战问题,系统地总结了植被退化、人工恢复、自然演替三个阶段植被、水文、土壤和溶蚀等观测实验得出的成果,阐述了喀斯特生态水文模型的发展及存在的问题。以地球关键带科学系统思维和多学科综合研究范式,提出了喀斯特地区大气-植被-土壤-岩石系统结构和组成以及协同演变理念;从多学科交叉、系统观测、模型集成视角,探讨了生态水文与碳、水、钙循环协同演变的研究途径,并以此提出推动喀斯特生态水文学发展的建议,为全球气候变化和绿色发展形势下喀斯特地区生态环境恢复提供科学支撑。
In view of the evolution history of ecology and environtment in karst area of sourthwest China and the challenges under the new situation,in this paper, the results of observation experiments on vegetation,hydrology,soil and dissolution test in three stages of vegetation degradation,artificial restoration and natural succession are systematically summarized, the development and existing problems of karst eco-hydrological model are expounded.The structure and composition of the atmosphere-vegetation-soil-rock system and the concept of coevolution in karst area are put forward based on the scientific system thinking of the earth critical zones and the multidisciplinary comprehensive research paradigm.The research approaches of the co-evolution of eco-hydrology and carbon,water,and calcium cycles are discussed from the perspective of interdisciplinary,systematic observation and model intergration.Based on this,this paper puts forward suggestions to promote the development of karst ecohydrology,so as to provide scientific support for the restoration of ecology and environment in karst area under the situation of global climate change and green development.
