Problems solved by technology

[0002] In the existing arborimetry, due to the lack of methods to accurately measure the volume of felled trees by using felling piles, it has seriously affected the accurate quantitative, qualitative and processing of deforestation cases, and made the investigation of logging area operations, forest resource planning and forest sites difficult. Condition classification, forest land fertility assessment, forest quality analysis, forest environmental protection research, etc. have increased labor intensity, low work efficiency and high cost

Embodiment 1

[0016] The method for measuring the volume of cut trees by using felling piles is:

[0017] (1) Measure and calculate the height of the cutting pile and the section diameter of the cutting pile;

[0018] (2) Substituting the following formula for the height of the felling pile and the section diameter of the cutting pile to obtain the diameter at breast height of the cut tree;

[0019] D=D 1 -[K(130-H)]

[0020] In the formula:

[0021] D - the diameter at breast height of the cut tree;

[0022] D. 1 ——diameter of cutting pile section;

[0023] K——The coefficient value of calculating the DBH of the felled tree with the diameter of the felling pile is 0.0154—0.0156;

[0024] H—height of cutting pile;

[0025] (3) According to the diameter at breast height of the felled trees calculated by the felling piles, the volume of the felled trees can be obtained by checking the one-yuan standing timber volume tables in various places.

[0026] For example, the pine trees in the ...

Embodiment 2

[0030] Utilize the present invention to measure and calculate its volume by the fir tree felling stake that is stolen:

[0031] Still taking the stolen Chinese fir tree in Xinhuang Forest District, Hunan Province as an example, the height of the felled pile and the section diameter of the cut pile are measured to be 20cm and 18cm respectively, and the diameter at breast height of the stolen Chinese fir tree obtained by substituting the above formula is:

[0032] D=18-[0.0155*(130-20)]=16.3(cm)

[0033] According to the diameter class of 16cm, check the volume table of the cedar tree in the county in one yuan, and the volume of the cedar tree that was stolen is 0.1048m 3 .

Embodiment 3

[0035] Utilize the present invention to measure and calculate its volume by the miscellaneous tree felling pile of stolen felling:

[0036] Still taking the stolen miscellaneous trees in Xinhuang Forest District, Hunan Province as an example, the height of the felling pile and the diameter of the section of the felling pile are measured to be 10cm and 8cm respectively. for:

[0037] D=8-[0.0155*(130-10)]=6.14(cm)

[0038] According to the diameter class of 6cm, check the volume table of the miscellaneous trees in the county in one yuan, and the volume of the miscellaneous trees that were stolen is 0.0099m 3 .

Abstract

The invention discloses a method which measures the cut timber volume through stumps, belonging to the forest mensuration. In order to overcome the deficiency of high operation strength and high cost in forestry administration case investigation treatment and forest resource planning and research due to the current lack of methods using stumps to accurately measure the cut timber volume, the invention enables the measured stump height and the cross-section diameter thereof to be calculated in a formula, namely, D is equal to D1- (K (130-H)), so as to evaluate the DBH (diameter at breast height) value of the cut timber, and then searches in the one-variable volume table of standing timber in each area based on the DBH value so as to evaluate the cut timber volume. The invention is used forthe detection, quantitativeness and qualitativeness in the deforestation cases, as well as the forest resource investigation, forest quality analysis, forest environmental protection and the like so as to significantly reduce the operating strength, save the manpower and save the costs by more than 50 percent.

Description

technical field [0001] The invention relates to a method for measuring and calculating forest resources, in particular to a method for measuring and calculating the volume of cut trees by using felling piles. Belongs to dendrology. Background technique [0002] In the existing arborimetry, due to the lack of methods to accurately measure the volume of felled trees by using felling piles, it has seriously affected the accurate quantitative, qualitative and processing of deforestation cases, and made the investigation of logging area operations, forest resource planning and forest sites difficult. Condition classification, forest land fertility assessment, forest quality analysis, forest environmental protection research, etc. have increased labor intensity, low work efficiency and high cost. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a method for measuring the volume of cut trees by using felli...
