Embodiment Construction

[0033] The present invention proposes a dynamic analysis method for the carrying capacity of an urban ecosystem, which is explained as follows in conjunction with the accompanying drawings and embodiments.

[0034] The present invention will establish a dynamic analysis framework by developing a coupling model of system dynamics and ecological footprint, predict and evaluate urban ecological carrying capacity from a dynamic perspective, and use the prediction results to reversely regulate urban ecological planning schemes, give scientific policy suggestions, and realize The sustainable development of urban ecology produces significant environmental and socio-economic benefits in practical applications. Among them, system dynamics, as an interdisciplinary subject that can understand the operation and interaction process between material flow, information flow and intervention measures in complex systems, is widely used in simulating complex systems of economic environment. Ecol...

Abstract

The invention discloses a dynamic analysis method for the bearing capacity of an urban ecological system, comprising the following steps: using system dynamics to stimulate a dynamic process and an interaction relationship of driving factors of the urban ecological system; establishing a response relation between the driving factors and the supply and demand of biologic resources through constructing submodules; utilizing an ecological footprint comprehensive accounting method to carry out ecological footprint accounting; taking a feasible and sustainable development goal as the standard to design different ecological regulation scenes to regulate and optimize urban sustainable development tendency. On the basis of traditional dynamic footprint analysis, in the method of the invention, a system dynamics thought is introduced and an endogenetic system modeling process is supplemented to stimulate the dynamic variation of the bearing capacity of the urban ecological system; the method can forecast the dynamic variation tendency of the ecological bearing capacity in the process of urban development, can utilizes the forecasting result to reversely regulate the planning scheme by combining a scenario analysis method, thereby optimizing urban ecological development.

Description

technical field [0001] The invention belongs to the field of environmental science, and in particular relates to a dynamic analysis method for the carrying capacity of an urban ecological system. Background technique [0002] With the rapid development of social economy, science and technology and rapid population growth, the process of urbanization in the world is constantly accelerating, especially in developing countries. How to adhere to the principle of sustainable development in the process of urban development, coordinate and unify urban population, resources, social economy and urban ecological environment construction, and promote the overall development of the city is an urgent problem facing the development of modern cities. Implement ecological city planning and construction It is an effective way to explore the sustainable development of urban ecology. At the same time, the scale, structure, and function of cities are limited by natural conditions, so urban eco...
