Embodiment 1

[0031] Example 1: Forestry Carbon Accounting Model in Sichuan Province

[0032] S1: Establish 15 main forest types in Sichuan Province (spruce, Yunnan pine, cypress, fir, masson pine, larch, other pines, birch, oak, camphor, nan, poplar, eucalyptus, hardwood, Soft broad) Spatial expansion equation of standing tree biomass with geographic variation. Established the carbon / nitrogen content parameter library required for forestry carbon measurement such as the various organs of the dominant tree species of the main forest types in Sichuan, the organs of the dominant shrub species, the litter of different forest types, the C / N content of soil organic carbon, and the plant photosynthesis such as the maximum carboxylation rate. Physiological parameter library (the parameter library is used in each module of the forestry carbon accounting model).

Abstract

The invention provides a forestry carbon accounting method based on an ecological process model. The forestry carbon accounting method based on the ecological process model comprises the following steps of S1, determining a plant physiological parameter, S2, setting a spatial interpolation, S3, building a forestry carbon accounting model, S4, building an interference module, and S5, determining a model initial state. According to the forestry carbon accounting method based on the ecological process model, the interference module is provided for simulation of land use changes and felling, dynamic changes of forest carbon cycles of the Szechwan province and influence caused by different interferences can be truly reflected, simulation is more accurate, rapid and accurate compilation of greenhouse gas emission inventories relevant to forestry of different levels of China and provinces, and the compilation process is perfect, and meets the international requirements.

Description

technical field [0001] The invention belongs to the field of measurement, and in particular relates to a method for measuring carbon content based on an ecological process model. Background technique [0002] The measurement of carbon content is related to the measurement of specific or macro-regional carbon stocks, and the formulation of emission inventories for international carbon emissions treaties. Accurate carbon content measurement is the main means. However, experimental observations can only reflect changes in ecosystem processes at a specific scale, such as the measurement of carbon storage in a sample plot at a certain point in time (Zhou Zhiyong. Research on the Calculation Method of Forest Community Carbon Storage in Baihuashan Nature Reserve, Northwest Journal of Agriculture and Forestry University, November 2012). Therefore, it is difficult to reveal the underlying mechanism of the interaction between different main control factors in ecosystem processes and ...
