遥感技术在上海立体绿化调查与规划中的优点与局限分析

Analysis of Advantages and Limitations of Remote Sensing in Vertical Planting Investigation and Planning in Shanghai

由于立体绿化对于改善城市环境具有明显效应,上海近些年来正在大力推广立体绿化。然而,立体绿化在调查与规划上面临着难以掌握现状和潜在资源的难题。在上海的应用中,使用高分辨率航空遥感影像有效解决了上述难题。实践结果表明,遥感技术具有较多优点,同时也存在一些局限性。对此进行了分析,并针对局限性提出了相关对策。

Vertical planting has obvious functions in the improvement of urban environment. In recent years, vertical planting has been promoted vigorously in Shanghai. However, the investigation and planning of vertical planting faces the difficulty in the mastering of current status and potential resources. In Shanghai, the application of high resolution remote sensing images has solved the above problem effectively. The practical applications in Shanghai show that remote sensing has many advantages as well as some limitations. Through analysis, some relative ways are given for the limitations of remote sensing.
