摘　　要：在林业六大工程项目实施和林业生产管理过程中,林地小班面积的测算是一项非常重要的工作,传统的林地小班面积测量方法存在费时、费力,且精度偏低。借助现代测量仪器全站仪的程序测量功能,对不规则的林地小班进行面积测量,具有速度快、精度高、易操作的特点。由于该法不受地形高低影响,更适合林地小班面积测量。同时得出了面积测量精度可超过1/497。对现代林业生产管理、项目实施和科学研究起到一定促进作用。In the implement of the six projects and the management of the forest production, the measurement of the forest compartment area is an important job, however, the traditional method is time-consuming, strenuous and low precision. By the special program measurement of the modern surveying instrument -the total station, the factual area of the irregular topography can be measured and it bears simple, quick, and high precision. Because the method can avoid the influence of the topography, it adopts the measurement of the forest compartment. At the same time the precision can reach 1 to 497. It promotes the modem forest production management, the project implement and the scientific research.
