      Spatial Decision Support System (SDSS) is indispensable to develop spatial planning alternative by integrating spatial parameters into forest management plans using ecosystem based multiple use forest management planning concept (EBMUFM). As part of this study, a SDSS was developed based on EBMUFM philosophy. The system has the capability to control the spatial strucutre of forests based on the spatial database generated by Geographical Information Systems (GIS) and spatial paramaters with other attribute data (such as empirical yield table, product assortment table, water production table). The SDSS was developed with object-oriented design and programming (Delphi) language, and has the flexibility to accomodate changes in model strucure. A simulation and a meta-heuristics based spatial forest management models were developed to link strategical planning with tactical planning on a sub-compartment (stand) bases and to present results with a number of performance indicators as outputs in map, graphic and table formats. SDSS has important component to determine all spatial characteristics with spatial parameters and patch description. A prototip stand simulation model based on the relationship bwtweeen actual and optimal basal area development (BARSM) was also developed to project the future stand characteristics and analyse the affects of various silvicultural treatments.
