数字化技术在城市绿地调查中的应用

摘要

In recent years, with the development of information technology and improvement of digital city construction, many cities have built a professional platform of information system in urban garden greening by using digital technologies, realizing the standardization and scientification of landscaping management. Meanwhile, due to such an extraordinary change, investigation of city greenland, as a fundamental work of urban garden greening, is in urgent need of being improved in the aspect of efficiency and quality. On the basis of the summary of the main content of China’s urban garden greening works, this paper puts forward that the principal technologies utilized in the urban garden greening digital work are: remote sensing, database technique, geographic information system, and global positioning system,etc. The authors thinks that with the help of the digital technologies in urban green space investigation, a more precise in the results of urban green space spatial distribution investigation, higher efficiency in the col ection of fundamental information and deeper depth of the green space investigation can be realized.%随着信息化技术发展和数字城市建设的推进，国内一些城市在城市园林绿化工作中，利用数字化技术，构建了行业信息化平台，实现了行业精细化、科学化管理。城市绿地现状调查作为城市园林绿化的基础性工作，也亟待通过数字化技术的应用提高其调查的效率及质量。在归纳我国城市园林绿化数字化工作主要内容的基础上，提出了我国城市园林绿化数字化工作涉及的主要技术包括：遥感技术、数据库技术、地理信息系统技术及全球定位系统技术等；接着通过分析城市园林绿地现状调查工作的主要内容，详细阐述了以上技术在城市园林绿地现状调查工作中的应用，并认为在城市绿地调查中，利用数字化技术，可以实现城市绿地空间分布调研结果的精准化、提高基础资料收集的效率、提升绿地调查分析的深度。
