• Environmental functions of tropical forest can serve as criteria for forest conservation planning in the tropics. The objective of thisstudy is to evaluate the environmental functions of tropical forest in Kinabalu Park. Sabah, Malaysia, using GIS and remote sensing techniques. Field data. statistical data. including weather data with geographic localities, maps and satellite image are collected.Linear regression models are developed for forests of different geological substrates, based on the relationships between altitudeand biodiversity (Fisher's alpha index). Biodiversity conservation function map is derived with the statisrical models and a digitalelevation model. Coupling with extensive literature review, an evaluation matrix for evaluating soil and warter conservationfunctions including landslide prevention, flood prevention and drought prevention functions, is constructed. To evaluate the soil andwater conservation functions, a weighted linear combination method is used with GIS layers of topography, geology, soil depth, rainfall and slope. Forest areas in Kinabalu Park are derived with land cover mapping using Landsat-TM image. Areas having high values of biodiversity conservation, flood and drought prevention functions are covered with mainly lowland rain forest. On the otherhand, areas with high values of the landslide prevention function are covered with mainly subalpine forests. Using the environmentalfunctions, a conservation index is computed to represent forests that are important to conservation. Based on the Cl, the lowland rainforest receives highest priority in protection. In fact. it is located in the boundary areas of the park and thus exposed to illegal aclivities.
