中文摘要
        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。
英文摘要
        Nowadays, innovation is becoming a powerful driving force behind the discipline development. With the strong long-term support of the Chinese Academy of Sciences, the Ministry of Science and Technology of the People's Republic of China, the National Natural Science Foundation of China, and the local government of Guangdong province, by means of long-term monitoring and innovative research, Dinghushan Forest Ecosystem Research Station (hereinafter referred to as the "Dinghushan Station") found the scientific phenomenon that old-growth forests can accumulate carbon in soils, illustrated the mechanism of forest organic matter accumulation and its driving mechanism from macroscopic to microscopic scale, leading the research on carbon, nitrogen, and water cycle processes of forest ecosystem, including their coupling in response to the environmental changes and the adaptation of the ecosystem, therefore, promoted the establishment of the ecological systems non-equilibrium theory. Dinghushan station acquired scientific quantification on the current carbon sequestration capacity and the potential of national forest ecosystems, which provided an important scientific support for the national environmental diplomacy. Such demonstration of a global pattern of forest and water yield, and accurately giving the critical value of the parameters describing water yield controlling factor linking climate and watershed characteristics, provided a new interpretation on the controversial of "the relationship between forest and water yield", it has far-reaching implications for scientific research and natural resource management. A shift in climate conditions could result in changes in tree species distribution and forest composition, whice has been verified by that the evergreen broad-leaved forest communities in China are changing toward shrub tendency, due to the adaptation to climate change in the past 30 years, such adaption was dominated by the main environmental factors, and the mechanism was demonstrated. These research conclusions provide theoretical support for the scientific evaluation of forest carbon sequestration and water resource, which meets the national needs for the construction of natural reserve and ecological environment. Until now, Dinghushan Station has become an irreplaceable national field scientific supporting platform and an international well-known research base of forest ecological systems. Meanwhile, it is also an ecology talent cultivation base for the Chinese Academy of Sciences and the Guangdong region.
