长期生态学研究引领中国沙区的生态重建与恢复

长期生态学研究揭示了干旱沙区土壤水循环的植被调控机理,解决了降水小于200 mm沙区植被建设的关键技术,提出了生态恢复的技术体系及其应用模式;引领了荒漠生物土壤结皮的研究,探明了人工植被稳定性维持的机理,拓展了荒漠系统生态恢复的生态水文学理论基础,推动了干旱逆境生理生态学的研究,在国内外产生了重要影响,为我国风沙危害治理和沙区生态重建与恢复提供了基础理论和技术支撑。

Long-term Ecological Research Guides Ecological Restoration and Recovery in Sandy Areas of Northern China

In more than 60 years since the foundation of Shapotou Desert Research and Experiment Station (SDRES) of Chinese Academy of Sciences, SDRES has been committing itself to serving the national needs, and made important progresses in the realms of sand hazards control, the reconstruction and restoration of desert ecosystems, eco-hydrology of sandy lands, and drought stress physiology and ecology. SDRES had been awarded the State Science and Technology Advancement Prize for two times (one for the top-class prize, and one for the second-class prize), and won the Best Practice Prize in Combating Desertification by United Nations Development Program. SDRES was also elected to the Global 500 Roll of Honor for Environmental Achievement by the United Nations Environment Program. Long-term ecological research (LTER) in SDRES revealed the vegetative regulation mechanisms within soil water cycle of arid desert areas, developed the key techniques for vegetation construction in desert areas with rainfall < 200 mm, formulated the technique system and application paradigm for ecological restoration, clarified the mechanisms in maintaining stability of artificial revegetation, broadened the eco-hydrological theoretical basis of ecological restoration within desert ecosystems, promoted the studies in drought stress physiology and ecology, and is leading the studies associated to desert biological soil crusts. Long-term ecological research (LTER) in SDRES had also made great influences both at home and abroad, provided the basic theory and technique support for combating wind and sand hazards and for the ecological reconstruction and restoration in sandy lands of China, and had made a great contribution to China''s practices in sand prevention and control.
