()
摘要:
利用静态GPS进行森林基本控制测量,遥感资料进行森林资源样地的规划和设计,全站仪进行调查样地的测绘.全站仪自动测算树木的三维坐标、胸径、任意处直径、树高,采用数学模型计算森林的面积,材积和蓄积.利用数字成图软件CASS绘制树木分布图和森林资源分布图,通过专家系统和相关的GIS软件进行分析,从而实现城市森林资源的实时监测和评价.

Monitoring and evaluation of urban forest based on the broad 3S technology
()
Abstract:
Statistic GPS can be used to the forest basic manipulative surveying, the programming and design of the forest resources sample are determined according to RS data, the sample surveying and mapping are used by Total Station. The trees three-dimensional coordinate, trees height, stem diameter, arbitrary stem diameter can also be calculated by Total Station. The urban forestland area and trees volume can be calculated by mathematics former. The trees and forestry resource distributing graphics can be protracted by CASS software and analyzed by expert system and interrelated GIS software, the real time surveying and evaluation of the urban forest resources can be realized.
Key words:  GPS  GIS  RS  Total Station  CASS  forest monitoring
