三维地表基质体元模型构建与生态修复应用研究
Research on the Construction of 3D Ground Substrate Voxel Model and Application of Ecological Restoration
摘要
Abstract
Ground substrate research is very important for promoting coordinated management of mountains,rivers,forests,fields,lakes and grass,and maintaining the stability of ecosystem.Based on multi-source data,TIN construction theory,and TIN to CPG algorithm,we constructed a vector database of ground substrate,studied a refined 3D modeling method for ground substrate,and established the entity models of ground substrate.Then,taking Nan'an District as an example,we illustrated the construction and ecological restoration application of 3D model of ground substrate.The results show that the spatial structure of 3D ground substrate voxel modeling gives the region an intuitive and visual overall concept.Various spatial analysis,process simulation and evaluation decisions are carried out based on the attributes of ground substrate,which lays a data foundation for the practical applications of regional natural resources,ecological restoration and evaluation,and prediction and simulation of the evolution law of ground substrate eco-geological environment.关键词
