Application of ecological classification system in China''''s digital forestry
试论生态分类系统在我国数字林业建设中的应用

In China's conventional forest management system,there are two types of sub-compartment,i.e.,the 2nd-and 3rd-level sub-compartments,which are concurrent but inconsistent in size and boundary locations.Even in the same type of sub-compartments,the inconsistency still existed at different time,which is unbeneficial to the long-term forest management planning by using digital technologies.With the mountainous region in eastern Liaoning Province as a case,this paper established an ecological classification system(ECS),which contained 5 ecological land types(ELTs) and 34 ecological land type phases(ELTPs).Based on the basic technical needs of China's digital forestry,the ELTPs could be used as a fixed sub-compartment system.A compatible forest inventory system was designed then.It was concluded that ecosystem management based on ECS and geospatial information technologies combined with computer models and decision-support systems would be the important component of digital forestry.
