World Forest Watching by Digital Earth

The application of Chinese meteorological satellites FY 1 and FY 2 in monitoring global forest resources is introduced. The new strategies for global forest resources re allocation are discussed when China joins the WTO. The Green Great Wall--"Tri North" Shelter Belt in the new century and the effect of forest on the global environmental change are also discussed. From the global viewpoint, the forest resources strategy facing the WTO is discussed. The forest resource is very poor, but its daily consumable amount is very large, for example, Chinese chopsticks, packing box of the shirts and the Oriental Set Board ect. Therefore, actions must be taken to protect ecologic environment. Every country now has known that forest resource is very important to global environment protection. An example of this is to recover plowland to forest and grassland in order to abate CO 2 emission. National Natural Reserves and Protected Areas give some good demonstrations of protecting eco environment. The characteristic of forest in Fanjing Mount. in Guizhou Province of China and its special contribution to the world demonstrate the forest role in environmental protection. The planning and construction of Chinese forest resources database and forest management information system are proposed for the 21st century. Digital Earth can be used to monitor forest dynamic change and establish "Digital Forestry" information system. We should apply the power of Digital Earth, and protect "the Lung of the Earht"--global forest resources. It is a huge information system project to set up "Digital Forestry". Since our country established, the Chinese departments of forestry survey, planning and administration have accumulated plenty of data and investigation information, and made many surveys by Remote Sensing and gained experiments by using information system. The establishment of the digital forestry system will promote the use of the data, share and co construct resource and environment data, and standardize the release and exchange of Chinese forestry information. By these, China will make contribution for monitoring forest dynamic change using "the Digital Earth".
