摘要：逻辑检查是林业调查内业统计工作的一项重要内容,是对前期调查数据的核查认定。基于数据处理流程,设计了前逻辑检查方法和后逻辑检查方法。前逻辑检查包括样地因子逻辑检查、样木因子逻辑检查和多期数据相关检查。其中多期数据相关检查在以往单期数据逻辑检查的基础上,加入了多期数据的纵向比对,有利于处理数据存在的各种逻辑错误问题。后逻辑检查对统计计算后的同期林分因子进行互算,并用邻期林分因子进行比对,可以较大程度地检查出数据录入和程序计算的纰漏。利用VB和内置SQL语言开发了相关程序工具,将逻辑检查方法嵌入到程序中,以提高工作效率。
Logical inspection is an important part of the statistical work of forestry investigation,and it is also the verification and confirmation of the previous investigation data.Based on the data processing flow,this paper designs the pre-logical checking method and post-logical checking method.Pre-logical checking includes sample factor logic checking,sample tree factor logic checking and multi-period data correlation checking.Multi-period data correlation checking adds multi-period data vertical comparison on the basis of previous single-period data logic checking,which is conducive to dealing with various logical errors in data.After logical checking,the stand factors of the same period after statistical calculation are calculated and compared with those of the adjacent period,and most of the data input and program calculation errors can be checked out.At the same time,this paper uses VB and built-in SQL language to develop relevant program tools,and embeds the logic check method into the program.
