Optimization method for urban industrial structure based on environmental carrying capacity

Abstract

The invention relates to an optimization method for an urban industrial structure based on environmental carrying capacity and belongs to the technical field of urban industrial planning and management. The optimization method for an urban industrial structure based on environmental carrying capacity comprises the following steps: step 1: setting up urban system dynamics model, step 2: setting development scenarios, simulating and analyzing the influence of the social and economic development on the resource,energy and environment under each situation, evaluating the environmental carrying capacity by the a comprehensive index method; step 3: setting up inexact multi-objective optimization model, the optimization target function comprises total revenue of urban economy and population quantity; the constraint condition comprises the supply amount of resource and energy, environment amount, per capita GDP and nonnegativity restrictions; the optimized urban industry structure is obtained by running the optimization module; step 4: setting the optimization development situation and the environmental carrying condition under the optimization development condition, and putting forward to the industrial structural optimization scheme and suggestion. The method provided in the invention has accurate simulation precision, complete evaluation, strong targeting, simple applicability, wide application range, etc.

Description

technical field [0001] The invention belongs to the technical field of urban industrial planning and management, and in particular relates to an urban industrial structure optimization method based on "system dynamics simulation simulation" coupled with "uncertain multi-objective optimization" under the constraints of environmental carrying capacity. Background technique [0002] At present, with the rapid development of social economy, science and technology and the rapid growth of population, the process of urbanization is accelerating. However, the long-term extensive production of "high investment, high consumption, and high emissions" has always been the main way of economic development, which has led to a continuous increase in the use of resources and energy and the discharge of pollutants, far exceeding the carrying capacity of the urban environment. It is the main restricting factor of urban sustainable development. The industrial system is the interaction interfac...
