针对不规则三角网(TIN)结构的省级基础DEM产品的动态更新需求，本文优化设计了包含属性信息的TIN数据结构及其组织模式，开发了一套顾及多源数据特征约束的TIN动态更新方法，并以1：10000比例尺DEM数据为例进行实验，验证了该方法的有效性。

Aiming at the dynamical updating demand of provincial-Level fundamental DEM product with triangulated irregular network(TIN) structure, this paper developed an optimal data structure of TIN, which specially contains rich attribute information. Taking the multi-source terrain feature constraints data into account, the algorithm of constrained Delaunay TIN dynamic generation is designed and implemented. Furthermore, the effectiveness of this method proposed in this paper has been verified by the experiment using the real data of 1:10000 DEM.
