摘要
以Ｂｕｆｏｎ随机投针问题为原理，对线截抽样的概念作了系统的介绍，并在此基础上提出了以线截抽样为原理的线状物体的调查方法。在计算机上成功地模拟了路网调查，从模拟的几种方案可以得出：线截抽样完全适用路网调查，且以本文中的Ｂ、Ｃ两种方案为好，并可以以此推广到林网及防护带的调查。
On the principle of Buffon's needle,this paper describes systemly the concept of line intersect sampling and introduces systemly the method for survey the linear shape object with line intersect sampling.We can obtain the concluson by modeling survey road net on the computer that line intersect sampling is good for survey the linear shape object and the sample effect for estimating the roadsand zones by using the straegy B and C are better than those by use straegy A and sigli-line sampling.
