摘　　要：景观建筑作为风景名胜区中的重要要素,对其色调、形状、体量等信息的把控极为重要.以百里峡景区入口处景观建筑为研究对象,借助GF-2号遥感影像,采用基于对象的规则分类法对其进行解译,借助ArcGIS平台优化建筑边界,计算其长度和宽度,利用太阳高度角、卫星方位角和阴影长度计算得到建筑物高度信息.通过实地测量得到建筑物实际长、宽、高信息,利用计算值与实测值之差的绝对值与实测值的百分比计算得到各个景观建筑的百分比误差.结果表明,长度、宽度和高度的误差为0.79%~17.14%,解译精度均在80%以上,其精度基本能够满足风景资源调查评价和风景区规划的实际需求.Landscape architecture is one of the most important elements in scenic areas,it is very important to control its color,shape,volume and other information.This paper takes the landscape architecture at the entrance of Bailixia scenic area as the research object,and uses object-based rule classification method to interpret buildings and shadow information at the entrance of Bailixia scenic area based on GF-2 remote sensing image.The boundary of buildings is optimized by using ArcGIS platform,and the length and width of buildings are calculated.The height information of buildings is calculated by using solar altitude angle,satellite azimuth angle and shadow length.The information of the actual length,width and height of building is obtained by field measurement,and the percentage of absolute value of the difference between calculated value and measured value and actual value is used to calculate percentage error of each landscape architecture.The results show that the error values of length,width and height are between 0.79%and 17.14%,and the interpretation accuracy is greater than 80%.The accuracy can basically meet the actual needs of landscape resources survey and evaluation and scenic area planning.
