摘要
近几十年来,由于人类活动和气候变化的共同影响,我国生态系统持续退化,严重影响经济社会的可持续发展。为了保护和修复生态系统,我国先后投巨资启动了三北防护林体系建设、退耕还林(草)、石漠化综合治理等重大生态工程。如何全面及时地掌握重大生态工程实施的生态成效及存在问题,以便滚动调整生态工程实施方案、保障工程实施效果,并使后续生态工程部署具有科学性和空间针对性,是国家的重大迫切需求。为此,国家重点研发计划"典型脆弱生态恢复与保护研究"设立了"国家重大生态工程生态效益监测与评估"项目。通过项目实施,构建重大生态工程生态效益监测评价指标体系,研发各类重大生态工程生态效益监测评估技术体系及系统,定量评价重大生态工程的生态效益,提出生态效益提升的技术途径,为国家重大生态工程的布局和管理提供科学依据。
In tern of our country recent decades, due to the combined effect 9f human activities and climate change, the ecosys- has been continuously degraded, seriously＇ affecting the sustainable economic and Social develop- ment. In order to protect and recover the ecosystem, China has invested heavily in launching a series of key ecolog- ical programs and projects including North Shelter Forest Program, Grain for Green Project and integrated ecosys- tem management of rock desertification. How to comprehensively and timely grasp the ecological effects and existing flaws of the implementation of key ecological projects so as to Scroll the implementation of ecological projects and ensure the implementation effect of the projects, and promote .the follow-up ecological engineering deployment of be- ing scientific and space-oriented is a major imperative for the country. Therefore, the National Key Research and Development Program of China set up the project of ＂Monitoring and Assessment of Ecological Benefits of Key Eco- logical Engineering in China＂. Through the implementation of this project, we will establish an indicator system for monitoring and evaluating the ecological benefits of key ecological projects, developing various technical systems for monitoring and evaluating the ecological benefits of key eco/og^cal projects, quantitatively evaluating the ecological benefits of key ecological projects, and concise the technical approaches to enhancing ecological benefits. We will provide a scientific basis for future planning and management of key ecological projects.
