Traditional isovist analysis, an important analysis method in scenic spot planning, is based on the line of sight and the viewshed of sight in GIS, which is ground on the single point of sight. The main problem of this kind of isovist analysis is short of the relation with the structural composition of the scenic area, such as the trail organization and the architecture location selection. The paper tried to combine the isovist analysis of GIS with the social networks analysis, put forward the concept of sight structure of viewshed quantification analysis method on the example of Baizhangji-Fciyun Lake Scenic Site, Wenzhou, Zhejiang Province, aiming to provide scientific basis for the structural layout in scenic area planning.%可视性分析是景区规划中重要的分析方法,传统的可视性分析是依赖地理信息系统中的视线和视域计算进行的.主要问题是分析结果只针对单个视点,与整个风景区规划中的结构布局、游线组织、设施分布及建筑选址等问题缺乏联系.以浙江温州文成百丈漈—飞云湖风景名胜区修建性详细规划为例,尝试将地理信息系统中的视域分析与社会网络分析方法相结合,提出视域景观结构的量化分析方法,目的是为风景区规划的结构布局提供科学的依据.
