小班蓄积调查指的是二类小班蓄积量的调查。《森林资源调查主要技术规定》要求按小班提供蓄积量,同时用抽样方法控制调查总体的蓄积量精度。但对远期开发的林区和经营强度较低的林区,可按小班进行分类,按林班或运材系统、大队或公社为总体提供资源数字。蓄积量调查的精度只落实到总体,而不要求落实到小班。二类小班调查的方法,三十年来,由目测、实测及标准地推测等方法,发展到目前广泛应用的总体抽样控制精度的小班调查法。从1976年起就想利用数量化方法进行二类小班蓄积量调查,但试验的结果,小班蓄积预
Small-scale accumulation refers to the investigation of small-sized accumulation of two types of small-scale survey. The Main Technical Regulations of Forest Resources Survey require that small-class reserves should be provided, while sampling methods should be used to control the overall accuracy of the survey. However, forest areas for the long-term development and low-intensity areas for forest management may be classified into small groups and resource figures provided by the forest classes or timber transportation systems, brigades or communes as a whole. The accuracy of stock volume survey is only implemented in the whole, but not required to be implemented in small classes. In the past 30 years, the methods of small class surveys in the second category have been developed by the methods of visual inspection, actual measurement and standard speculation to the small class survey method widely used in the overall sampling control precision. Since 1976, he wanted to use the quantitative method to conduct class two small-scale stock volume survey, but the results of the experiment, small-scale accumulation
