以前我省山地人工林小班资源的调查方法,多以目视选择一亩方形标准地推算,由于标准地选择时主观性强,使蓄积量的估计值难以置信。随着林业科技和生产的发展,许多同志都在探讨既省工、省力,又具有一定精度的估测方法。原省林调队首先应用抽样技术,为我省山地人工林小班蓄积调查方法提供了依据。近年来,省内国营林场Ⅱ级经理 调查中也已采用了小样园、角规、簇状园等小单元抽样,对此,有的持不同见解。为探讨和改进调查方法,验证小单元抽样在我省山地人工林小班资源调查中适用性,在原省林调队试验研究的基础上,我们又在泰山林场和历城县柳埠林场进行了可行性试验。现 In the past, the investigation methods of small-scale resource in mountain plantations in our province were mostly extrapolated by the visual selection of a square of standard acreage. Due to the subjectivity of standard selection, the estimation of the accumulated volume was unbelievable. With the development of forestry science and technology and production, many comrades are discussing ways of estimating labor, labor and accuracy. The provincial forestry transfer team first applied the sampling technique, which provided the basis for the investigation of small-scale accumulation of mountain plantations in our province. In recent years, the survey of Class II managers in the state-owned forestry farms in the province has also used sample sampling of small units such as sample plots, angle gauges and tufted gardens, and some hold different opinions. In order to explore and improve the investigation methods and verify the applicability of sampling of small units in the investigation of small-scale forest resources in mountainous areas in our province, based on the experimental study on the adjustment of forestry and forestry in the original province, we conducted feasibility studies in Taishan Forest Farm and Liubu Forest Farm in Licheng County Sexual test.
