Method for assessing total output value of marine ecosystem

Abstract

The invention discloses a method for assessing the total output value of a marine ecosystem. The method comprises the technical steps that the ecological environment data of an evaluated sea area are collected, wherein the data comprise the area of the evaluated sea area, the yield and the market price of various kinds of seafood fished and cultivated by mankind and raw materials produced by the sea, the cost for fixing carbon dioxide, the cost for releasing oxygen, primary productivity, environment capacity, the cost of manual treatment of pollutants and the like; a marine ecological environment database is established; an assessment system of the total output value of the marine ecosystem is established; the total output value of the marine ecosystem is evaluated, data are retrieved from the marine ecological environment database, the marine ecological supply value, the marine ecological adjusting value, the marine ecological cultural value and the marine ecological supporting value are assessed respectively according to the assessment system of the total output value of the marine ecosystem, and accordingly the total output value of the marine ecosystem is obtained. The method for assessing the total output value of the marine ecosystem fills the blank of assessment of the total output value of the marine ecosystem, the value of the marine ecosystem is made to be dominant based on the conversion method of the marine ecological environment, a simple computing method is formed, and a popularization and application prospect is achieved.

Description

technical field [0001] The invention relates to the marine ecological environment and marine economy, in particular to a method for assessing the gross production value of the marine ecosystem based on the conversion of the value of the marine ecological environment. Background technique [0002] The ocean is an important part of the global ecosystem. With its unique geological and geomorphic structure, physical and chemical properties, and biological composition characteristics, the marine ecosystem exerts an irreplaceable ecological value of other natural ecosystems. Especially with the continuous rise of the "blue economy" in recent years, the marine ecosystem has been paid more and more attention by people. From the perspective of production value, pay attention to the value contribution of marine ecosystems to human beings, and establish a scientific marine ecosystem value evaluation system, which is the premise and basis for understanding, managing and protecting marin...

Problems solved by technology

[0003] At present, the value evaluation methods of marine ecosystems only focus on their service value, which is basically the imitation and application of terrestrial ecological value theories and methods, but there is no feasible technical method for the evaluation of the gross production value of marine ecosystems, which is difficult. Adapting to People's Requirements for Accounting the Value of Marine Ecosystem

The theory and evaluation methods of marine ecosystem service value have not formed a technical method system that can be quickly applied. This is mainly because the value of marine ecosystem services is based on the service value humans obtain from marine ecosystems. It is difficult to calculate the value in detail, it is still at the stage of discussion, and it cannot be connected with the accounting system of gross domestic product (GDP)
