Establishment and application of forest resource management information system in Shilin County

Geographic information system (GIS) is widely applied in forestry due to the tempo-spatial dynamics of forest resource information in geolocation, multidimension structure and time-series attributes. In this paper, establishment of forest resource management information system is presented by GIS and other techniques such as RS and data driving. Based on the tempo-spatial data of forest resource in Shilin County of Yunnan Province, forest resource management information system is applied in information archive management, resource inventory and supervision, special analysis and macroscopic decision, etc. The results show that viewing platform which is based on geolocation data is available in obtaining and management of forest resource information; high resolution satellite data integrated with forecasting model of stand growth can supply accurate updated data timely; spatial analysis method and diverse resource information can promote dynamics study, classified regime and construction of early warning and monitoring system of forest resources.
