Problems solved by technology

[0007] Aiming at the problem that the prior art methods cannot objectively evaluate the environmental impact of the industrial system with a unified measurement standard, the present invention uses the emergy theory to design a method based on the unified measurement standard of "emergy" to define the industrial system and analyze the economic benefits and ecological pressure and the method of carrying out industrial ecological economic evaluation, through this method, the structural analysis of energy value utilization of the industry, the analysis of the level of industrial development and the evaluation of the priority of industrial development can also be carried out

Embodiment example

[0027] To analyze and evaluate the three leading industries in a certain city, the emergy flow diagrams are as follows: Figure 1 ~ Figure 3 shown.

[0028] According to the above method, the emergy utilization structure of the three can be analyzed, and the results shown in Table 1 can be obtained.

[0029] Table 1 Analysis results of emergy flow of major industries in a city

[0030]

[0031] By comparing and analyzing the changes of the three leading industries in a certain city over the years, we can get Figure 4 ~ Figure 6 analysis and evaluation results.

[0032] Depend on Figure 4 It can be seen that the emergy / money ratios of each system show different degrees of reduction. Compared with the national emergy currency ratio, the moso bamboo industry is greater than the national average, and the tourism and tea industries have fallen below the national average. That is to say, in the process of trade with other domestic systems, the tea industry makes more profits...

Abstract

The invention belongs to the field of researches of ecological economics, ecological thermodynamics and industrial systems, and relates to a method for analyzing and evaluating the ecology characteristics of a specified industrial system from the standpoint of ecological thermodynamics. Aiming at the problem that industrial system environmental effect can not be objectively evaluated by a uniform measurement criteria in the prior art, the method based on the uniform measurement criteria of energy value, which defines industrial systems, analyzes economic benefits and economic pressure and develops industrial and ecological economy evaluation, is designed by utilizing the energy value theory. By adopting the method, industrial energy value utilization structure and industrial development level can be analyzed, and industrial development priority level can be evaluated. The method can be used for the research on single industry and the contrast research on different industries, and can be applied to industry zones, enterprises and other systems.

Description

[0001] Field [0002] The invention belongs to the fields of ecological economics, ecological thermodynamics and industrial system research, and is a method for analyzing and evaluating ecological characteristics of a designated industrial system from the perspective of ecological thermodynamics, and is especially suitable for comparative research on economic benefits and ecological pressures of different industries. So as to judge the priority development sequence of regional industries. Background technique [0003] An industry is a collection of chain or network enterprises (or individuals) that produce a certain type of product (or provide a certain type of service) in a region, that is, the sum of all links closely related to the production of a certain type of product (or service), and is an important part of human economic activities. important form of expression. The traditional industrial evaluation method focuses on the evaluation of economic benefits, ignoring the ...
