当前,TI—59型可编程序计算器在林业调查规划中已逐步推广使用。通过实践证明,使用TI—59机解决林业调查规划中的有关计算,可大量节省人力,节约时间。根据“森林法”(试行)规定:“对森林要实行合理采伐。以县或者国营林业局为单位计算,每年的森林采伐量不得超过生长量”。为了确定合理的采伐量,首先必须计算生长量。因此,以县(或国营林业局)为单位,计算各树种的生长量已是当务之急。
Currently, TI-59 programmable calculator in the forestry survey planning has been gradually promoted. Practice has proved that the use of TI-59 machine to solve the calculation of the forestry survey planning, can save a lot of manpower and save time. According to the “Forest Law” (Provisional), “Proper logging of forests is carried out, and the annual amount of forest harvesting shall not exceed the amount of growth calculated by the county or the state-owned forestry bureau.” In order to determine a reasonable harvest, we must first calculate the amount of growth. Therefore, the counties (or the State Forestry Administration) as a unit, the calculation of the growth of each species is a top priority.
