Problems solved by technology

[0004] The current research on carbon storage of forest vegetation does not analyze the spatial heterogeneity deeply enough, the main reason is that the scale effect is not fully considered
There is little research on this

Embodiment 1

[0082] Primary forests, lightly felled Korean pine-spruce forests, larch-spruce fir forests, over-cut forests, and bare-land secondary forests in Fenglin Nature Reserve and its subordinate Lilin Experimental Forest Farm in Heilongjiang Province were selected as analysis objects.

[0083] Table 3 below shows the forest types and important values ​​of the sample plots

[0084]

[0085]1) Community characteristics of coniferous and broad-leaved mixed forests in primary forests

[0086] The original representative vegetation of the Xiaoxing’an Mountains is the Korean pine broad-leaved mixed forest, and the original vegetation of the Korean pine broad-leaved forest in the Lilin Experimental Forest Farm (sample plot 01) and the Fenglin Nature Reserve (sample plot 02) were respectively selected for analysis. Both are the original vegetation of Korean pine broad-leaved mixed forest, but there are certain differences in tree species composition.

Abstract

The invention relates to the technical field of forest analysis. The invention and particularly relates to a method for analyzing the type and community characteristics of a small-khingan stigma-broadleaf mixed forest based on carbon reserves. The method comprises the following steps of sSelecting an original forest in a top-level state; using secondary forests formed by mixed forests of felling forests and over-felling forests and natural renewal succession are used as analysis objects; setting the method comprises the following steps: 1, preparing raw materials; standard sample plots setting, adopting a sample method and an arbor positioning method are adopted. The method comprises the following steps: to carry outcarrying out variety identification, listing and positioning on arbor andsmall arbor plant individuals, measuring the tree height, diameter at breast height, height under branches and crown breadth, calculating the biomass of each measured arbor by using a biomass method,calculating the carbon reserve, and analyzing sample plot population distribution through a vertical projection area, a mixing degree, an angular scale and a competition index by using a statisticalmethod. According to the method, tThe influence of the carbon reserves on the forest stand structure is analyzed by taking the carbon reserve difference shown by different forest stand structures as an entry point, and a theoretical basis is provided for correctly evaluating the carbon sequestration capability of the stigma-broadleaf mixed forest in the region and scientifically managing forest resources.

Description

technical field [0001] The invention relates to the technical field of forest analysis, in particular to a method for analyzing the types and community characteristics of mixed coniferous and broadleaf forests in Xiaoxing'an Mountains based on carbon storage. Background technique [0002] The coniferous and broad-leaved mixed forest in the Xiaoxing’an Mountains is the main zonal forest vegetation in Northeast my country and a typical temperate mixed coniferous and broad-leaved forest. It has the characteristics of unique construction species, rich species diversity, and complex spatial structure. As much as 1 / 3 of the total forest area, it plays an important role in my country's forest carbon sink research and environmental protection. At present, most of the research on the spatial distribution of forest carbon stocks is based on the sub-class statistics collected by administrative provinces / counties, and the estimation accuracy is generally low. [0003] Some scholars have...
