Multifunctional lighting measuring instrument for tree-shrub-herb layer plant morphological indexes

Abstract

The invention discloses a multifunctional lighting measuring instrument for tree-shrub-herb layer plant morphological indexes, comprising a circular tree layer branch angle protractor, a shrub layer morphological index lighting measuring box, and an herb layer morphological index lighting measuring box. The herb layer morphological index lighting measuring box is mounted inside the shrub layer morphological index lighting measuring box. The circular tree layer branch angle protractor is mounted above the shrub layer morphological index lighting measuring box. The center points of the circular tree layer branch angle protractor, the shrub layer morphological index lighting measuring box and the herb layer morphological index lighting measuring box are in a vertical line. The shrub layer morphological index lighting measuring box and the herb layer morphological index lighting measuring box are each internally equipped with a rechargeable lamp capable of adjusting the brightness. According to the invention, people can look up at the included angle between a trunk and a lateral branch of a measured shrub layer on the ground, and the included angle between a large first branch and a large second branch can also be measured. The multifunctional light measuring instrument has a lighting function.

Description

technical field [0001] The invention relates to an illumination measuring instrument, in particular to a multifunctional illumination measuring instrument for plant morphology indexes of trees, shrubs and grass layers. Background technique [0002] In the process of field plant community survey, plant morphological indicators follow the traditional community survey methods, usually ignoring the measurement of plant morphological indicators in the arbor, shrub and grass layers. Contents of the invention [0003] In order to solve the above problems, the present invention provides a multi-functional light measuring instrument for plant morphology indicators of arbor, shrub and grass layers, which can not only measure the angle between the main trunk and side branches of the arbor layer on the ground, but also some larger first branches The angle between the second branch and the second branch can also be measured, and it has a lighting enhancement function. [0004] In orde...
