中文摘要	巨大的人口压力和相对有限的资源,脆弱的生态系统,加上史无前例的城市化和经济发展速度与规模,对中华民族的可持续发展和生存问题提出了严峻的挑战.为应对这一挑战,必须明智地进行土地的规划和利用,通过国土生态安全格局的构建为明智的保护和发展提供科学的空间区划依据.国土尺度生态安全格局通过对江河源区水源涵养、洪水调蓄、沙漠化防治、水土保持和生物多样性保护5个维护生态安全最关键的自然过程进行系统分析评价而划定.首先对单一生态过程进行分析与评价,得出各自相应的生态安全格局；在此基础上通过叠加、综合,初步构建基于5种生态过程的国土尺度生态安全格局.结果表明,最低标准安全水平的生态安全格局面积占我国陆地总面积的35.7%,中等安全水平的生态安全格局面积占我国陆地面积的65.1%,高安全水平生态安全格局面积占我国陆地总面积的84.9%.将为国土与区域尺度土地利用规划、生态安全格局规划和主体功能区划工作提供借鉴.
英文摘要	China,with its huge population and relative meager natural resources,fragile ecosystems,plus the unprecedented urbanization and economic growth in terms of speed and scale,is facing sever challenges of sustainability and survival.Addressing these challenges requires that the national land should be planned and used wisely.This research is a pilot project aiming at establishing ecological security patterns at the national scale that will protect the most sensitive ecological landscapes and critical pattern as a strategy for wise conservation and wise development.Critical natural processes are analyzed systematically at the national scale,including headwater conservation,soil erosion prevention,storm water management and flood control,desertification combating and biodiversity conservation.Individual security patterns for safeguarding each of these natural processes are identified and then integrated into an overall ecological security pattern.Three levels of National Ecological Security Pattern are defined,the lower security level,the moderate security level and the higher security level,which account for 35.7%,65.1% and 84.9% of the national land respectively.This study is expected to provide a scientific basis for the under-going national function zoning and land use planning at the national scale.
