In order to conform forest management to the concept of ecosystem management, we have to develop and apply the database of ecosystem management as the basis. There are biological, temporal and spatial factors in the database. Establishing and analyzing the data of long-term monitoring and inventory, we could derive and set up the criteria and indicators of ecosystem management. Therefore, we specify the ecological unit first, and zoning the soil units and watershed regions in this study. We construct the multi-scale forest ecosystem database in Huisun Forest Experimental Station under the hierarchical system of single tree, stand, community, landscape and region. The Chi-Chi earthquake of 921 caused a large area of slide in Huisun Forest Experimental Station, and the slide disturbed the function of original forest ecosystem. Multi-scale forest ecosystem management database were developed by geographic information system (GIS) and Remote Sensing (RS). Slide area were interpreted with orthogonal colored aerial photos, and then we explore the spatial characteristic of slide area and land classification and draw up the recovery step in slide. The abstract of this research results are as follows:
1.Aiming at specifying the soil and watershed of ecological unit by the hierarchical zoning method, we apply soil units and watershed ecological units to do integration and division.
2.To collect the data of forest inventory and management records of Huisun Experimental Forest Station in hierarchical structure, we developed multi-scale forest ecosystem management database of Huisun Experimental Forest Station. Modelling and sampling methods were used to connect each hierarchical data, and the data could be share by researchers and managers.
3.To interpret the slide areas of digital colored aerial photos of Huisun Experimental Forest Station. The results showed that the slide area of digital aerial photo is 549.16 ha, which is 7.35% area of Huisun Experimental Forest Station.
4.Analysis the relationship between the river, road and slide, we found that the relationship between the slide areas, road and river are obviously. The closer to the river and road, the bigger the slide areas are.
5.For developing methods of recording the slide area, we classify the slope into six classes and the soil types into five classes, then intersection calculation were used to group into five forest classes. The suggestions of community recovering were presented, also.
