Embodiment Construction

[0021] Compared with the existing monitoring methods, a method for monitoring the whole process of standing tree growth has been greatly improved, specifically:

[0022] 1) Use red paint to surround the first original mark point at the standing tree 1.3m from the ground, measure and record the diameter d of the standing tree here 1.3 , and measure the total height of the standing tree as H;

[0023] 2) Use red paint to surround and set another second and third original mark point at 1 / 3H and 2 / 3H of the standing tree to be measured, measure and record the standing tree height h of these two places respectively 1 / 3H 、h 2 / 3H and the standing tree diameter d 1 / 3H 、d 2 / 3H ;

[0024] 3) One year later, use the same method to measure the DBH value d at 1.3m again 1.3 , the standing tree height h at 1 / 3H and 2 / 3H 1 / 3H 、h 2 / 3H and the standing tree diameter d 1 / 3H 、d 2 / 3H Measure and mark, when the height increase h≥2 / 3H, add a new mark point, and then use the same method to ...

Abstract

The invention discloses a stumpage growth whole process monitoring method. The method provided by the invention is mainly used for monitoring the small-scale stumpage growth whole process. Red paint is used to mark the breast diameter of a stumpage at 1.3 meters as d1.3. The breast diameters of 1/3H and 2/3H are marked as d1/3H and d2/3H, and the heights of two marks are h1/3H and h2/3H. When the height of the amount of growth h is greater than or equal to 2/3H, a mark is added. In later growth process of the stumpage year by year, the same method is used to measure and mark the numerical values at the same date. Based on the measurement values ht, dt, ht+1 and dt+1 year by year, a stumpage growth equation is established. Transverse and longitudinal growth rules of the stumpage are reflected.

Description

[0001] 1. Technical field [0002] The invention relates to a method for monitoring the whole growth process of a standing tree, in particular to a method for monitoring the whole growth process of a non-destructive standing tree. [0003] 2. Technical Background [0004] Forest resource monitoring is one of the hotspots in current global change research and sustainable development. The monitoring of the whole process of standing tree growth refers to the systematic measurement, observation, recording, analysis and evaluation of its resource status by using information collection and processing methods within a certain time and space range, so as to reveal the status of various factors in the process of regional resource changes. The internal law of relationship and change shows its evolution track and change trend, meets the needs of standing tree resources evaluation, and provides decision-making basis for rational management of standing tree resources and sustainable develop...
