| 摘 要： | 采用4种不同方法对小班杉木林蓄积量进行调查,分别记录工时,其结果表明用航空像片设计带状样地调查小班森林蓄积量实际精度达到97.7％,工效为标准地调查的1.7倍,模拟样地的2.7倍,全林实测的5.7倍。所以用航空像片设计带状样地,是调查小班森林蓄积量的较好方法之一。

| Abstract: | The author employed four kinds of methods in the standing crop survey of Cunninghamia lanceolata. The facts proved that strip sample method based on the aerophoto was the best one of estimating the forest growing stock of subcompartment, actual accuracy reached 97.7%, effect was 1.7 times that sample plot, 2.7 times that analog quadrat, 5.7 times that actual measurement. |
