| 摘 要： | 中国科学院鄂尔多斯沙地草地生态研究站（以下简称“鄂尔多斯站”）自建站以来,针对我国沙地草地荒漠化严重的问题,以沙地草地生态系统为研究对象,从各个层次上对草地沙化产生和发展的过程和机理进行长期定位研究,为区域经济可持续发展、荒漠化防治与环境治理提供理论基础和实验示范。30年来,鄂尔多斯站基于长期监测、野外调查和长期控制实验,揭示了气候变化和人类干扰下沙地草地生态系统的过程变化和稳定性的维持机制,引领了沙地植物生态学的研究,在国内外产生重要影响。主要贡献包括：（1）揭示了沙地植物对环境的多样适应对策;（2）阐明了植物性状间耦合关系与生物多样性的大尺度变化规律;（3）探明生物/非生物因子对沙地生态系统结构与功能的调控机制;（4）开创性提出荒漠化综合治理的“三圈”范式,推动了区域可持续发展。为我国沙地生态系统的恢复重建和生态生产功能提升提供理论与技术支撑。

| Abstract: | Since its establishment, the Ordos Sandland Ecological Research Station, the Chinese Academy of Sciences (hereinafter referred to as Ordos Station) has aimed at the serious problem of the desertification in sandy grasslands in China. Taking the sandy grassland ecosystem as the research object, the Ordos Station has conducted long-term monitoring and research on the process and mechanism of grassland desertification at all levels, which has provided theoretical basis and experimental demonstration for regional economic sustainable development, combating desertification and environmental management. Over the past 30 years, based on long-term monitoring, field investigation, and long-term experiments, the Ordos Station has revealed the process and mechanism maintaining the stability of sandy grassland ecosystems under climatic change and human disturbance, which has led the research of sandy plant ecology and had an important impact in China and abroad. The main contributions include:(1) revealed the diversified adaptation strategies of sandy plants to the environment; (2) clarified the coupling relationship among plant traits and large-scale variation patterns of biodiversity; (3) verified the regulation mechanism of biological/abiotic factors on the structure and function of sandy ecosystem; and (4) creatively put forward the optimized "3-circles" eco-productive paradigm for sustainable management of desert lands, which has promoted regional sustainable development. These contributions have provided theoretical and technical supports for the restoration and reconstruction of sandy grassland ecosystems and the improvement of ecological functions in China. |
