| 摘 要： | 随着GIS在森林资源管理中应用的不断深入，在GIS系统中实现林业专业抽样设计功能是非常必要的。本文使用MapBasic鳊程语言实现三种样点布设功能。操作时，用鼠标点击欲布样点区域，在弹出对话框中作出回答，就能得到样点布设图和样点坐标表。

| Abstract: | There are usually two random sampling methods in forest resources surveying: simple random sampling, systematic sampling. With GIS rapidly developing in forest resources management, it is important to add special function of sampling design to GIS' software system. In the pape, author realizes three sampling distributing-point functions with MapBasic programming language. While practical running, user clicks the sampled region, answers the questions in dialogue frame, and then obtains sampling-point map and coordinate table. |
