Embodiment Construction

[0022] The present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings. The following is the specific operation process of the best embodiment, and the protection scope of the present invention is not limited in any form by the embodiments.

[0023] A method for assessing fishery carbon sink function, such as figure 1 As shown, the basic data required by the method through investigation or literature review include: ①The amount of resources is Y 0 ; ②The average trophic level is TL 0 ; The current average trophic level of China's offshore fishery resources is between 3 and 4; ③ The ecological conversion efficiency of each trophic level is ECE; ④ The carbon content of phytoplankton is C%; for example, the Y 0 = 29,4314 tons; TL 0 =3.70; C%=4.49% (the average value of 10 kinds of phytoplankton carbon content); ECE=-15.615TL+86.235; Concrete assessment method is as follows:

Abstract

The invention relates to a fishery carbon sink function evaluation method, which belongs to the field of ecology and comprises the following steps: firstly, obtaining basic data: (1) resource quantity, namely Y0; (2) the average nutrient level, namely TL0; 3, the ecological conversion efficiency of each nutrition level, namely ECE; 4, the carbon content of phytoplankton, namely C%; and then carrying out estimation: (1) estimating the biomass B1 of the fishery organism feeding the next nutritional organism; (2) determining proportion P of phytoplankton ingested by next nutrient level organism and proportion of phytoplankton feeding organisms according to nutrient level calculation formula; (3) estimating the biomass B0 of feeding phytoplankton; (4) estimating the existing carbon content C1of phytoplankton; and (5) finally estimating the carbon sequestration amount C according to the fact that the carbon sequestration amount of phytoplankton is 45 times of the existing carbon content ofphytoplankton. The method provided by the invention can simply and quickly evaluate the carbon sequestration functions of various water organisms, and provides a basis for developing low-carbon economy.

Description

technical field [0001] The invention belongs to the field of ecology, and in particular relates to an evaluation method of fishery carbon sink function. Background technique [0002] Global climate change and its impact are becoming more and more serious, not only attracting the attention of the scientific community, but also gradually attracting great attention from the international community and governments. At present, the development of low-carbon economy has become a strategic choice for governments to deal with climate change. The core of developing a low-carbon economy is to reduce the amount of greenhouse gases such as carbon dioxide in the atmosphere. As far as the current level of science and technology is concerned, fixing and storing greenhouse gases in the atmosphere through biological carbon sequestration is not only technically feasible and low-cost, but also can produce multiple benefits. core content. Biological emission reduction and sink enhancement ma...
