Abstract: With the help of digital elevation model and geographic information system, five indicators of cost data, including slope, aspect, relief, relative distance of existing tourism roads, and relative distance of existing view points, were selected to evaluate the land suitability of Houshi National Forest Park in Xinbin of Fushun City. An integrated suitability evaluation model was then established, and the lands with the potential of developing and constructing scenic sites in the Park were classified into four classes of suitability. The lands of classes I and II occupied 897% of the total area of the Park (especially of class 2, they occupied more than half of the total area), while those of classes Ⅲ and Ⅳ only occupied 97% and 06% of the total, respectively, which indicated that most parts of the Park could be selected as the sites for the development and construction of view points.
