Detection method for forest carbon sink

Abstract

A provided metering method for forest carbon sink comprises the following steps: steps 1, staining cell nucleus; step 2, calculating cell wall percentage; step 3, calculating tree species volume; and step 4, calculating forest carbon sink, respectively calculating the carbon sink of each tree species according to the following formula: C[i]=0.5*10<3>*r[i]*V[i], wherein C[i] is the carbon sink of one tree species, r[i] is the tree species cell wall percentage of the tree species, V[i] is the volume of the tree species, and summing the carbon sink of all tree species, so as to calculate the carbon sink of the forest, in other words, C=C[1]+C[2]+...+C[i], wherein C is the forest carbon sink, and n is the tree species sum. The metering method for the forest carbon sink is capable of relatively accurately metering the forest carbon sink, difference of carbon sink capability of different tree species at different areas is fully considered, the forest carbon sink is dynamically metered, and disadvantages of static metering is overcome.

Description

technical field [0001] The invention relates to a detection method of forest carbon sink. Background technique [0002] The global climate change caused by the greenhouse effect caused by the accumulation of greenhouse gases such as carbon dioxide is a major environmental problem facing human beings. As the main body of terrestrial ecosystems, forests play a very important role in the global carbon cycle. Therefore, detecting forest carbon sink capacity is of great significance for the study of global climate change. Using different carbon sink detection methods, the results obtained are not the same. At present, forest carbon sink detection methods mainly include biomass method, stock method, and biological inventory method based on biomass method and stock method. [0003] The biomass method is currently the most widely used method. This method is to calculate the forest biomass and multiply it by the biomass-carbon storage conversion factor to obtain the forest carbon s...

Problems solved by technology

However, the level of research, the degree of sophistication, and the estimation methods vary from region to region, making the method less reliable and comparable

[0006] Existing carbon sink detection methods mainly estimate forest carbon sinks based on biomass, so the estimated results obtained are static and cannot reflect the dynamic development trend of forest carbon sinks.

Moreover, because there are many uncertainties in the study of carbon sink function of forest ecosystems, many assumptions and indirect judgments must be adopted in the above methods, resulting in low accuracy of the research results, which greatly affects the global The scientificity and reliability of carbon sink change prediction
