采伐剩余物的线截抽样技术理论研究

Study on the Line Intersect Sampling Technology for Estimating Logging Wastes

研究了采伐剩余物调查的线截抽样原理和方法。在应用中既可使用单条样线进行估计，也可以使用多条样线进行估计。在计算机上应用线截抽样估计原理模拟了采伐剩余物的调查情况，结果表明在8次模拟中7次实际精度达到80％以上，有一半在90％以上。

The principle and method of line intersect sampling for estimating logging wastes are introduced in this paper. Having done the experiments through computer to estimate logging volume in different intensity of logging wastes, the author state that the accuracy of logging wastes has achieved more than 85%, and half of them than 90%.
