摘要
介绍了历次一类调查结果和江西省同期一、二类调查主要指标。提出当二类调查全部用抽样控制时,用估计区间作比较,而二类调查部分和全部未作抽样控制时,以允许误差为标准作比较;一类调查资料用于制定本地区的林业计划、规划以及对外数据公布等,二类调查资料用于分解计划、规划到二类调查单位等。
Introduction was made on first class survey results in China and the major index of first and the second class survey in Jiangxi province in the corresponding period. Using estimating intervals to make a comparison when completely using samples to control second class survey, using allowable error as a standard to make a comparison when none or partly using samples to control second class survey. Suggestion was put forwards to the first class survey data be used for making forestry plans of the area and be published etc., and second class survey data could be used to decompose plans to second class survey units.
