Abstract

The invention relates to an MCR city expansion simulation method with optimized ecosystem service value, an MCR minimum cumulative resistance model is applied to city expansion simulation, and city expansion simulation oriented by ecosystem service value optimization is realized through optimization of a traditional weight definite value and a scenario simulation method. The expansion model can simulate the urban expansion simulation scene under the optimization of the service value of the ecosystem according to objective data and a statistical method, so that the simulation result of the model can reappear, and meanwhile, the quantitative evaluation of the value optimization level can be carried out.

Description

technical field [0001] The invention relates to an MCR urban expansion simulation method for optimizing ecosystem service value. Background technique [0002] Due to severe problems such as unreasonable urban expansion, weakening of environmental carrying capacity, reduction of cultivated land reserve resources, and decline of ecological environment quality, the sustainability of the urban ecosystem is facing a huge test. In order to estimate urban expansion and its impact, scholars use spatial expansion models to simulate the process of urban expansion. Such as CA model, multi-agent model, MCR minimum cumulative resistance model, CLUS-S model, etc., and there is a research and development trend of changing from a single model to an integrated model. [0003] In the operation of the existing urban expansion simulation model, there are mainly the following two problems. On the one hand, the determination of the weight coefficient has an important impact on the construction ...
