浅谈地理信息系统中空间分析功能在城乡规划中的应用——以平衡南丰县洽湾船型古村保护与开发规划为例

Talking About the Application of Spatial Analysis Function in Geographic Information System in Urban and Rural Planning——A Case Study of Balancing the Protection and Development Planning of the Qiawan Village in Nanfeng County

在地理信息系统中空间分析是其重要的运用形式之一,因人们对城市乡村的空间感受主要处于可视范围下,故地理信息系统-空间分析-视线分析的重要性不言而喻。文章以南丰县洽湾镇船型古村为例,浅谈GIS空间分析技术在传统村落保护与开发中的应用,通过运用传统村落周边CAD地形图快速建立数字模型,对周边规划范围内的高程、坡度、坡向、视线等进行分析,将视线分析建立在全面直观的分析模型之上,从而实现规划设计前期对传统村落视线通廊保护的合理性分析,对之后传统古村落保护与开发的规划设计工作的有效指导。

Spatial analysis is one of the important forms of application in geographic information system （GIS）. Because the spatial sense of urban villages are mainly in the visible range, the importance of geographic information system - spatial analysis and sight analysis is self-evident In this paper, seting the Qiawan Village in Nanfeng County as a example,analyzes the application of GIS spatial analysis technology in the protection and development of traditional villages. The digital model is established by using the CAD topographic map around the traditional villages,the elevation, slope, aspect, profile, line of sight and so on in the surrounding planning area are analyzed., analysis of the line of sight in a comprehensive and intuitive analysis model.The paper analyzes the rationality of the protection of the traditional sight line corridor in the early stage of planning and design,In order to achieve pre-planning and design reasonable analysis of the traditional village corridor line of sight protection and draws the bright spot of the planning and design,to make effective guidance of the planning and design work of ancient village protection and development,
