Forest soil carbon reserve research method

Abstract

The invention discloses a forest soil carbon reserve research method which includes the steps: collecting samples including arbor, shrub, herbal, dry branches and fallen leaves and soil; detecting andanalyzing the carbon content of the collected sample to obtain the proportional relation of the carbon content of the arbor, the shrub, the herbal, the dry branches and fallen leaves and the soil; and detecting and analyzing to obtain the distribution characteristics of the carbon content of the community and the change of the carbon cycle of the quercus liaotungensis forest region in the Ziwuling mountain. According to the forest soil carbon reserve research method, the main problems of existing quercus liaotungensis forest area in the Ziwuling mountain can be known according to analysis ofdetection data, and the problems are that young tree seedlings in the quercus liaotungensis forest area in the Ziwuling mountain are few, shrub and grass under the forest are few, and natural forest renewal is affected, the seedling rate and the preservation rate are extremely low, and the difference of different site conditions is remarkable. Once the forests on the upper layer disappear, oak succession is interrupted, other tree species or shrubs are replaced, and natural renewal of the forests is seriously affected.

Description

technical field [0001] The invention relates to research related to soil carbon storage, in particular to a research method for forest soil carbon storage. Background technique [0002] In recent years, the issue of carbon storage has increasingly become a frontier and hot issue in the field of global change and earth science research; soil is the core of terrestrial ecosystems, and the study of soil carbon cycle and carbon storage is one of the hot topics in current terrestrial ecosystem carbon cycle and global change research. 1. The storage of soil carbon storage reflects the carbon sequestration capacity of the soil system. Determining the storage and spatial distribution of soil carbon storage is the basis for studying the carbon cycle of terrestrial ecosystems. An important means of calculation is a basic work for establishing soil carbon inventory, assessing its historical deficit or surplus, and predicting soil carbon sequestration potential; forest ecosystem, as the...

Problems solved by technology

[0003] The Ziwuling forest area spans Shaanxi and Gansu provinces, and is located in the hinterland of the Loess Plateau. It is a relatively complete natural secondary forest area in the Loess Plateau; it is located in an uplifted mountain area, and the rainfall is more abundant than the surrounding areas. The climate type is humid and cool in the temperate zone; In recent years, studies on soil carbon content in forest areas have also been carried out in Quercus liaotung forests, but there is a lack of research on the relationship between the carbon content of different growing trees, shrubs, herbs, litter and soil in the forest area, so it is impossible to more accurately Find out some problems existing in the forest carbon cycle system
