摘要
兴义万峰林是国家级风景名胜区马岭河峡谷的重要组成部分,也是中国锥状喀斯特发育最典型、最完整、最集中的地方。应用GIS技术,利用高分二号1 m空间分辨率多光谱遥感影像数据,结合资源三号立体像对提取的栅格分辨率为10 m数字高程模型,分析并评估了万峰林及景区峰头个数。通过ArcGIS山顶点提取算法,运用山顶点高差阈值提取的等高线转换为面状图进行了叠置分析,提取了万峰林峰头个数为8972个,其中景区内峰头个数为3309个,研究结果可为贵州喀斯特地域的研究及生态旅游的发展提供一定的借鉴作用。
Wanfeng Forest was an important part of Malinghe Gorge,a national scenic spot.It was also the most typical,complete and concentrated place of cone Karst development in China.Based on GIS technology,the number of peaks in Wanfeng Forest and scenic spot was analyzed and evaluated by using the 1-meter spatial resolution multispectral remote sensing image data of GF-2 and digital elevation model with grid resolution of 10m extracted from ZY-3 stereo image pair.Through ArcGIS peak point extraction algorithm,the contour lines extracted by the peak height difference threshold are converted into area maps for overlay analysis.The number of peaks in Wanfeng Forest was 8972,including 3309 peaks in the scenic area.The research results provided a certain reference for the study of Guizhou Karst region and the development of eco-tourism.
