All parches are as individual ecological spots; human activity, precipitation distribution and heat quantity are as three major lines; and the functional characteristics of ecosystems are as surfaces. CFENS is formed by the combination of spots, lines and surfaces. The integral roles of forests should be maintained in a manner of safeguarding the long-term multi-functions, multi-effects and multi-directions, so that the water and soil loss, sandification and desertification in China could be controlled and improved, to decrease the damages from natural disasters of windy sand, drought and waterlogging, typhoon and sea tide, to enhance the capacity of territory security, to safeguard the Chinese people to live and work in peace and contentment, to enhance social civilization and progress, and to promote the sustainable development of resources, environment, society and economy.
