| 摘 要： | 林业调查中采用的基本方法是全林调查法和局部估测法，而局部估测方法中最常用的是角规测量法与标准地法，在林地调查中角规法误差较大，而标准地法又存在着难于布设的问题。本研究提出的面积单元线性测量法，可方便快捷地进行局部估测，节省人力和时间，同时又达到了较高的精度，特别适用于不规则林分的调查。 |

| Abstract: | The basic methods in forestry investigation are the whole and partly estimating. The methods of Augle Gauge and Standard Sample are usuall in partly estimating. The method of Augle Gauge has a deficency of large deviations. And Standard Sample has a difficult way to lay a unit square for investigation. Thus we offerded a new way-A measuring method through square unit by line. It can be convenint, efficent and practical, saving time and power, Particularly useful for those unregular forests. |
| Keywords: | square unit measure forest lands |
