摘要: 基于DEM,利用GIS空间分析功能,选取坡度、坡向、地形起伏度、相对现有游道距离和相对现有景点距离等5个成本数据指标,分别对抚顺市新宾猴石国家森林公园用地进行适宜性评价,并构建了综合适宜性评价模型,进而将研究区划分为4个等级适宜性的开发建设区域。综合适宜性评价结果表明,Ⅰ等和Ⅱ等适宜开发区的面积均较大,二者共计占研究区总面积的89.7%,尤其是Ⅱ等适宜区的面积达到664.7 hm2,占研究区总面积的1/2以上,表明研究区大部分地区都可作为景区选址的开发建设用地;Ⅲ等适宜区的面积为126.3 hm2,约占总面积的9.7%;Ⅳ等适宜区的面积最小,为7.3 hm2,仅占总面积的0.6%。

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.
