创新是引领学科发展的动力源泉。在中科院、国家科技部、国家自然科学基金委和广东省的长期支持下,中科院华南植物园鼎湖山森林生态系统定位研究站(以下简称“鼎湖山站”)以长期监测与创新研究为手段,发现成熟森林土壤持续积累有机碳现象,从宏观到微观的不同尺度阐明森林土壤积累有机碳的机理及其驱动机制,引领森林生态系统碳氮水循环过程及其耦合对环境变化的响应与适应规律的研究,推动生态系统非平衡理论的建立;科学量化了全国森林生态系统碳汇现状与潜力,为国家环境外交提供了重要的科学支撑;提出森林与产水量的全球模式并精确给出了控制产水量气候与流域特征参数的临界值,为“森林与产水量”关系的争论提供了新的阐释;发现常绿阔叶林群落适应气候变化在过去30年向灌丛化方向演替并阐明其受主要环境因子影响的机理。研究成果为森林固碳与水资源效应的科学评估、自然保护区和生态环境建设的国家需求提供了理论支撑。鼎湖山站成为国内外无可替代的野外科技支撑平台和国际著名的森林生态系统科学研究基地,也是中科院和广东地区生态学人才培养基地。
Innovation is the source of power to lead the development of disciplines. Under the long-term support of Chinese Academy of Science, Ministry of Science and Technology, National Natural Science Foundation of China and Guangdong Province, Dinghushan Forest Ecosystem Research Station (hereinafter referred to as “Dinghushan Station”) of South China Botanical Garden, Chinese Academy of Sciences takes long-term monitoring and innovation research as a means , And found that mature forest soil continuously accumulates organic carbon, clarifies the mechanism and driving mechanism of accumulated organic carbon in forest soil from different macroscopic and microscopic scales, and leads the response and adaptation of carbon and nitrogen cycling and its coupling to environmental changes in forest ecosystems Research and promote the establishment of ecological imbalance theory; scientifically quantify the status quo and potential of national forest ecosystem carbon sequestration, providing an important scientific support for the national environmental diplomacy; proposed a global model of forest and water production and accurate control given The critical values of water production and basin characteristic parameters provide a new explanation for the debate about the relationship between forest and water production. It was found that the adaptation of evergreen broad-leaved forest community to climax succession in the past 30 years And clarify its mechanism by the main environmental factors. The research results provide theoretical support for the scientific assessment of forest carbon sequestration and water resources effects, national needs for nature reserves and ecological environment construction. Dinghushan Station has become an indispensable platform for domestic and foreign field science and technology support and internationally renowned forest ecosystem research base, but also the Chinese Academy of Sciences and Guangdong area ecological personnel training base.
