【摘要】：黄土高原是我国生态环境最为脆弱的地区之一,同时也是我国大规模生态恢复的重点区域。经过数十年的治理,黄土高原生态环境得到显著改善,但一系列新的环境问题也随之出现,使得该区域大规模生态修复与治理的可持续发展成为当前的研究热点。为了对黄土高原生态系统演变规律和维持机制进行综合分析与探索,根据"十三五"国家重点研发计划《典型脆弱生态修复与保护研究专项指南》的要求,中国科学院生态环境研究中心牵头共10家单位联合申报了"黄土高原区域生态系统演变规律和维持机制研究"项目,通过了专业机构组织的评审,获准立项。对该项目的立项背景、总体目标、主要内容、研究方案等进行介绍。该项目的开展将对黄土高原生态修复的适宜性和可持续发展提供重要政策与决策支持。
[Abstract]:The Loess Plateau is one of the most fragile ecological areas in China, and it is also the key area for large-scale ecological restoration in China. After decades of management, the ecological environment of the Loess Plateau has been significantly improved. However, a series of new environmental problems have emerged, which make the sustainable development of large-scale ecological restoration and management in this region become the current research hotspot. In order to comprehensively analyze and explore the evolution law and maintenance mechanism of the ecosystem in the Loess Plateau, According to the requirements of the National key R & D Program of the Thirteenth Five-Year Plan, "Special guidelines for the Research on the Restoration and Protection of typical fragile Ecology," The Center for Ecological and Environmental Studies of the Chinese Academy of Sciences led a total of 10 units to jointly declare the project "study on the Evolution Law and maintenance Mechanism of the Regional ecosystem in the Loess Plateau", and passed the evaluation organized by professional organizations. The background, general objectives, main contents and research scheme of the project are introduced. The project will provide important policy and decision support for the suitability and sustainable development of ecological restoration of the Loess Plateau.
