摘要
南方红壤区和亚热带森林交错,是我国生态文明建设重要的空间载体;提升生态服务功能,传承健康稳定的生态系统,是区域可持续发展面临的重大挑战。中国科学院千烟洲亚热带森林生态系统观测研究站(以下简称"千烟洲站")地处亚热带典型红壤丘陵山区,以亚热带人工林、常绿阔叶林、次生林等生态系统为研究对象,采用长期定位观测、控制实验与模拟等方法,研究亚热带森林生态系统结构与功能。在国内率先引进碳水通量观测技术,突破了涡度相关与稳定同位素技术协同观测的技术瓶颈,从点到面阐明了我国亚热带森林对全球变化响应适应机制;揭示了流域尺度物质循环与生态水文过程耦合机制;创新人工林生态系统多目标经营理论、关键技术与示范模式;在地下生态过程研究取得突破性进展,首次提出了基于植物根系的植物进化理论。千烟洲站是以林为主、山水林田湖草生态系统恢复和可持续发展的典型代表,是我国亚热带森林生态系统功能演替序列研究的重要野外平台,已成为我国生命科学和地学交叉的代表性的综合观测研究站。
The subtropical forest and red soil hilly region interlace in southern China is one of the largest eco-environmental protection areas,and it plays a crucial role in ecological civilization and national sustainable development.Achieving sustainable development of the region requires extensive actions to make economic and social progress,and at the same time,to strengthen eco-environmental protection.Qianyanzhou Ecological Research Station,Chinese Academy of Sciences("Qianyanzhou Station"for short),locates in typical red soil hilly region,mainly studies the subtropical forest ecosystem structure and function.The station has observed the key ecological processes and patterns across plantations,evergreen broad-leaved forests,secondary forests,and other ecosystems for a long time.The station developed the"Qianyanzhou Model,"which successively controlled the soil erosion and significantly enhanced ecological services and economic benefits,set an excellent example for this ecological restoration.The station is the earliest forest site to observe carbon and water flux in China,breaking through the technical bottleneck of collaborative observation of eddy-covariance and stable isotope technology.Further,they studied the mechanism of how subtropical forests respond to global changes from trees to region,and clarified the subtropical forest was a vital carbon sink in the northern hemisphere.The satiation revealed the coupling mechanism of material cycles and eco-hydrological processes from water-catchment to Ganjiang watershed.Qianyanzhou Station built several important demonstration models of multi-purpose forest management,and developed theory for subtropical forest ecosystem and management.Based on long-term study of root ecological process,the researchers of the station have unearthed evolutionary theory and provided the explanations for the root economic spectrum.Qianyanzhou Station is a typical station for subtropical forest,and represents a holistic restoration and sustainable development for mountains,rivers,forests
