It is a specific type of systematic sampling, similar to other statistical sampling methods such as random sampling, but more straightforward to carry out in practice.〔Aver,T.E. and H.E. Burkhart. 2002. Forest Measurements. 5th Ed. McGraw-Hill. New York. 456 p.〕 This survey methodology is typically used to collect information about seedlings, shrubs, invasive species, signs of wildlife, need for fertilization, timber species count, and other similar types of data. For statistical control, all sample plots are a precise radius, typically , and must not include features outside each sampling circle. ==Method== The method is commonly used for forest inventories. It makes it possible to accurately estimate the volume standing in a forested tract without counting every single item. Inventory specialists set up a line or bearing on their hand compass and determine how many plots to take on this survey line. This is done by determining the distance between survey lines (B), the distance between plots (D), and the surface area (A) of the tract. The number of samples that should be taken is then calculated as follows: $n=\; \backslash frac$ The survey starts with the surveyor selecting two random numbers between (and B ) and (and D ) for the first plot and line location. The surveyor then measures the length to the first plot, surveys, and repeats the procedure. Once at the boundary, the surveyor turns 90° and continues on to the next transect. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Line plot survey」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
