Embodiment Construction

[0027] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the examples.

[0028] The research method of the forest soil carbon storage of the present embodiment comprises the following steps:

[0029] s1. Conduct vegetation surveys of different forest types

[0030] The coastal terraces of 12 cities and counties were surveyed by route survey and field quadrat survey, and finally 4 representative cities and counties (Wenchang, Lingao, Ledong, Wanning) of Hainan Island were selected from the coastal terraces of 12 cities and counties. Different forest types in the platform (mainly coconut forest, casuarina forest, acacia forest, eucalyptus forest, and rural secondary forest) were investigated and sample plots were established, and each sample plot was marked with cement boundary stakes or PVC pipes. The coordinate information of the sample plo...

Abstract

The invention discloses a method of researching forest soil carbon storage. The method comprises following steps of s1, investigating coastal platforms in multiple regions, and establishing a sample platform; s2, digging soil profiles of the sample platform inwards and outwards and collecting soil samples, and analyzing and measuring physical properties, chemical properties and biological properties of the forest soil; s3, researching a litterfall contemporary carbon characteristic, a root biomass stock carbon characteristic and microbial morphology carbon of each layer of the soil; s4, researching a distribution state and a stock characteristic of soil carbon of a main forest type in the coastal platform, and obtaining an accumulation characteristic of the forest carbon; and s5, estimating and researching storage of the soil carbon of the main forest type in the region. The method acquires accurate data through measurement of the sample platform so as to analyze a distribution law anda relationship between the distribution law and environment variables, thereby being conducive to ecological functions of artificial forest soil in the coasting platform and being significant for sustainable running of coasting platform forest and recovery of forest productivity.

Description

technical field [0001] The invention belongs to the field of forest soil carbon storage research, and in particular relates 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 research on soil carbon cycle and carbon storage is one of the hot topics in current terrestrial ecosystem carbon cycle and global change research. 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 method is a basic work for establishing soil carbon inventory, assessing its historical deficit or surplus, and predicting soil carbon sequestration potential. As the main bod...
