Embodiment Construction

[0030] The technical problem to be solved by the invention is to conduct laboratory analysis and quantitative estimation based on the principle of relevant carbon transformation, and conduct technical research and development for the evaluation of ecological forest carbon storage. like figure 1 Shown, the estimation method of a kind of ecological forest SOC reserves of the present invention, its main steps are as follows:

[0031] a) Obtain remote sensing information sources, identify ecological forest soil information, and obtain attribute data such as geographical location and ground cover status of each soil landscape type;

[0032] b) Analyze the attribute data of each soil landscape type described in step a) using a systematic method to obtain soil landscape pattern information;

[0033] c) Based on the information support of steps a) and b), determine soil sampling points and excavate typical profiles from spatial differences such as geographical location, ground vegeta...

Abstract

The invention discloses an evaluation method of soil organic carbon (SOC) storage in ecological forest, which belongs to the field of environmental monitor technology and low carbon economy and technology in forestry ecology. In the preparation method, the attribute data of the soil landscape type are obtained and subject to characteristic analysis to acquire the landscape pattern information. Soil typical sections are excavated and layered, and soil samples are collected and pre-treated. SOC information of the above soil samples is determined by potassium bichromate volumetric method and SOC estimation model is established thereby. Quantitative estimation of the SOC storage is carried out and multivariate data of the ecological forest are obtained. Temporal and spatial features and change law of soil organic carbon are analyzed. Characteristics and regularities of ecological effect of the ecological forest with carbon as the core are reflected by the method of the invention. The method also reflects the change law and objective characteristics of ecological forests comprehensively and systematically, thereby guiding the objective practice of CO2 emission reduction and the eco-economic development.

Description

technical field [0001] The invention discloses a method for estimating soil organic carbon (SOC) reserves of ecological forests, and belongs to the fields of forestry ecological engineering technology, environmental monitoring technology, low-carbon economic technology and the like. Background technique [0002] In terms of the occurrence forms of geochemical element carbon, the earth has four major carbon pools: atmospheric carbon pool, ocean carbon pool, lithosphere carbon pool, and terrestrial ecosystem carbon pool. The terrestrial ecosystem carbon pool includes vegetation carbon pool and soil carbon pool. carbon pool. Since soil is the main body of terrestrial ecosystems and there are a series of uncertainties, the estimation of terrestrial soil organic carbon (SOC) storage and soil carbon sequestration have become one of the important contents of ecology and global change research. [0003] The forest ecosystem is an important resource for maintaining ecological stabil...
