摘　　要：为提高林木材积计算速度和精度,该文使用Java程序开发中的jdbc技术,将通过解析木获取的材积计算公式转化成SQL语句存储在数据库中,先设置好需要统计的行政单位,将需要计算的树种、胸径、树高、株数等关键参数输入系统,计算机将会在后台自动调取对应的材积计算公式,对其进行自动计算。Java jdbc was used to improve speed and accuracy of the calculation of wood volume.The volume formula calculated by the analytic wood was converted into an SQL statement and stored into the database,set the administrative units that need to statistic,input the key parameters such as species,DBH,tree height,number of stem,and then the computer would automatically adjust the corresponding volume calculation formula in the background,and calculate it automatically.

关 键 词：JAVA编程 数据库 自动计算材积
