Abstract: In view of the reality of the serious crisis of forest resources in China,the paper discusses how to rely on scientific and technological advances in alleviating the crisis of forest resources.The research topic,for the first time,raises a theory of structural readjustment to stimulate the need,which emphasizes the effect and the coordination of the elements of systematic structure of forest science/technology-resources,and the rational and effective disposition.It first gives a review of the actual strength,capabilities and potential of forest science and technology,and analyses the foundation of forest resources in terms of total quantity and quality of the forest resources.According to the character of long period of forest growth,it puts forward a concept of resource magnitude for commercial timber forest,and makes a quantitative estimate of the effect of technological advances in expanding forest resources.Finally,ten corresponding measures are proposed.
