Embodiment Construction

[0012] The measurement method of forest disturbance degree of the present invention, its preferred embodiment is, adopt formula (1) to measure forest disturbance degree:

[0013] D = A 1 n - - - ( 1 )

[0014] In the formula, D is the degree of forest human disturbance, A is the average harvesting intensity, and n is the number of harvesting. The value of the interference degree D is a value between [0, 1].

[0015] In formula (1), the degree of forest disturbance (D) is the reciprocal power of the average logging intensity (A) of the number of harvesting (n), which can effectively measure the intensity of forest disturbance from logging activities.

[0016] The invention takes the impact degree of human-made logging activities on the forest as a starting point, and proposes a method for measuring the degree of forest human in...

Abstract

The invention discloses a method for measuring the degree of interfering a forest. The degree of interfering the forest is measured by a formula shown in the specifications, wherein D is the degree of artificially interfering the forest, A is average cutting intensity, and n is cutting times. D is the (one nth)th power of A, so the degree of interfering the forest by cutting activities can be effectively measured.

Description

technical field [0001] The invention relates to a forest measuring method, in particular to a measuring method of forest disturbance degree. Background technique [0002] 80% of the ecosystems on land have been disturbed by humans and nature, and forest ecosystems are no exception. Broadly speaking, forest disturbance is pervasive, intrinsic and unavoidable, with disturbance affecting all levels of the forest. Such as fire interference, wind interference, pest interference, snow disaster, low temperature freezing damage, flood, geological disasters and other types of natural interference, such as deforestation, logging, pruning, litter removal, grazing, fruit collection, mining, tourism, industry Man-made disturbances such as pollution. [0003] Due to the unreasonable and even predatory development and utilization (disturbance) of forests by modern humans, human disturbance is far greater than natural disturbance. Therefore, human disturbance has become one of the main fa...
