资源环境安全问题始终是世界各国持续发展的核心任务和基本诉求。考虑到单要素和整体两大分析方法的不足，提出一种针对性很强的要素综合分析方法。根据世界上10个人口超过 1亿以上国家的抽样分析表明，土地、水资源、矿产及生态环境的整体状态是决定国家资源环境安全的基本所在。与此同时，为了改善国家，特别是发展中国家的资源环境脆弱状态和提高其稳定程度，第一是要严格控制人口增长；第二是努力推进本国资源环境开发的国际化进程；第三是增大智力投入以提高资源深度化加工；第四是加大本国生态环境保护力度。

A fragile base of the natural resources and environment of China, the largest developing country in the world, can be characterized as compared with others. An analysis result of the national security of natural resource and environment by 10 selected countries with a population over 100 million in the world shows that China is in the place just ahead of Japan, but quite far behind all the eight others. More seriously, China will have to face greater and greater pressures on its weakened natural resources and environment base when a growing population and a rising living standard continue in the next 20 to 50 years. Obviously, China will needs to readjust its development policy if the country really does not want to ruin its weakened natural resources and environmental base totally. This paper, therefore, suggests that the paramount task for the country's sustainable development in the future should be to reconstruct its policy structure with a pronounced target of stabilizing and improving its weakened natural resources and environmental base. For such a purpose, a proposed model can be described as the following: 
   To concrete the natural resources and environmental base=a severe population control x (improving the production efficiency through intensified resource processing + reconstructing the nation's sustainable capacity through increasing scientific and technological inputs + expanding the nation's material base through international trade + enforcing the commonwealth's consciousness on the national security of the national resources and environment through education).
