摘要
以遥感手段发掘潜在旅游资源,对集中连片贫困区发展旅游业,推动脱贫致富具有重要意义。基于90 m分辨率的ASTER GDEM数据,采用相关矩阵法、OIF指数法、规则窗口法和均值变点法对湘西北潜在旅游资源进行探查和发掘。结果表明:(1)通过高程、坡度变率和全累计曲率最佳地形因子的组合可以最大化的反映影像中的地理特征信息;(2)对于湘西北地区,开辟尺度为12×12,面积为1.17 km^2的地形起伏度分析窗口最为合适;(3)通过遥感手段,借助地形因子,基于宏观发现微观探查的原则在湘西北地区成功发现3处潜在旅游资源:象形地貌类景观,湖光山色类景观和特色台地地貌景观。发掘结果对地方旅游资源开发具有一定的参考价值,验证了基于地形的生态旅游资源发掘方法的可行性。
Exploring potential tourism resources by remote sensing means is of great significance to the development of tourism in contiguous poverty areas and the promotion of poverty alleviation.Based on ASTER GDEM data with a resolution of 90 m,correlation matrix method,OIF index method,regular window method and mean variable point method were adopted to search and explore potential tourism resources in northwestern Hunan.The results indicated that:(1)the combination of the best terrain factors such as elevation,slope variability and total accumulated curvature could maximize the reflection of the geographic feature information in the image.(2)It was the most appropriate to open up a topographic relief analysis window with a size of 12×12 and an area of 1.17 km^2 in northwestern Hunan.(3)Three potential tourism resources were successfully discovered in the northwest region of Hunan Province by means of remote sensing,with the aid of terrain factors and based on the principle of macro discovery and micro exploration:pictographic landscape,lake and mountain landscape as well as characteristic platform landscape.The excavation results were of certain reference value to the development of local tourism resources,and then the feasibility of the topographical ecotourism resources excavation method was verified.
