Spatial Distribution Analysis and Structure System Construction of Water Conservancy Sights in Shaanxi
利用GIS和空间计量方法分析陕西省水利景观的空间分布特征，发现资源分布不均、集中于陕中南，并构建了包含增长点、潜力点和轴-节点-板块的空间结构体系。
This paper selected Shaanxi province as study area, using GIS techniques and geographic spatial econometric methods to analysis the spatial distribution characteristics of its water conservancy sights, and built the spatial structure system. The results showed that the resources were weak cohesion distribution; spatial distribution were unbalanced,mainly in central and southern Shaanxi, concentrated in Baoji, Xi'an and Shangluo city; the high- density area is Weihe river basin, while the low-density area is northern sandy marsh area; 2 big and 2 small ribbon area exist; 9 growth sights、87 potential sights、three levels axes-nodes and four water conservancy tourism plates built the spatial structure system.
