造林面积验收,若按以往的作业方法,一般要经过实测—绘图—量测面积三个步骤。其中除必不可少的实测外,还要进行一系列的内业。其中直尺与量角器的绘图以及用求积仪量测面积的各项操作是相当繁琐的,并且要求操作人员具备一定的实际经验和技能。在这种情况下,计算面积速度之慢是不问可知的。现笔者介绍一种观测与计算
Acceptance of afforestation area, according to the previous method of operation, generally go through the actual measurement - drawing - measuring area of three steps. Which in addition to the essential measurement, but also a series of internal work. Among them, the drawing of ruler and protractor as well as the operation of measuring area by using the plotter are quite tedious, and require the operators to have certain practical experience and skills. In this case, the calculation of the speed of the area is slow to ask. Now I introduce a kind of observation and calculation
