Abstract

The embodiment of the invention relates to the field of forest growth monitoring, in particular to a chest height diameter ruler used for monitoring forest growth. The chest height diameter ruler comprises a first ruler part and a second ruler part which are connected with each other, a first measuring scale and a second measuring scale are formed on the first ruler part and the second ruler partrespectively, and a through hole for the first ruler part to penetrate through is formed in the second ruler part. In the actual use process, the diameter at chest height of a forest tree is surrounded by the diameter at chest height diameter ruler, and the diameter at chest height of the forest tree can be measured through reading by enabling the first ruler part to penetrate through the throughhole in the second ruler part. Thus, growth of the forest tree chest height diameter can be monitored in real time, chest height diameter monitoring precision is greatly improved, measurement is accurate, installation is convenient, reading is visual, and cost is low. The chest height diameter ruler is used for experiment popularization.

Description

technical field [0001] The invention relates to the field of tree growth monitoring, in particular to a diameter at breast height for monitoring tree growth. Background technique [0002] Tree diameter at breast height is one of the important basic parameters for studying tree growth, and the study of the relationship between tree diameter at breast height and temperature and precipitation has become a scientific problem that needs to be solved urgently. [0003] At present, the diameter at breast height of forest trees at home and abroad is mainly measured with a diameter at breasth caliper or a girth tape. The DBH caliper can directly read the DBH size, but it needs to measure two diameter readings in the perpendicular direction at the DBH of the forest tree, and then take the average of the two results to obtain the DBH result. The girth tape measure is a stainless steel ruler or tape measure of equal width. The diameter is directly recorded on the ruler according to the...
