超站仪技术在树木测量中的应用研究

Study on the Application of Total Station in Forest Measurement

为了实现对树木高精度无损的测量,掌握每棵树的树高、树冠等因子,以便实现对林木生长趋势的更好研究,来预测树木生物量,反映林地生产力,本文以超站仪在北京市二类调查项目的应用为例,介绍了超站仪在林木测量中原理的运用,结合项目本身,讨论其实施方法、注意事项,对测量精度和测量的特殊环境进行了分析,提出3维树木体积测量的新方法,并且精度达到90.14%。实践证明,超站仪在树木测量较常规仪器具有很大的优势,为当代精准测量提供了数据保障。

For the sake of realization of height of the tree accuracy measurement through the factors, such as the height of the tree, tree crown etc in order to realize a better research of the trend of the growth of the forest, predict the trees biomass and reflect the land productivity, the article takes the application of the total station in the second measurement project as an example to introduce the prin- ciple of total station in the forest measurement, discuss the manner of execution and notes, and analyses the measurement accuracy and the special measurement environment. The paper puts forward the new method in the 3D trees volume measurement and achieves the 90.14% accuracy. In practice, comparing to the general instruments, it has proved that the total station has the great advantage, and provides the data assurance for contemporary precise measurement.
