Application of Contact Number in Suitability Evaluation of Human Settlement Environment—Taking Jiangxi Province as an Example

Abstract

The human settlement environment is a dynamic subsystem in which people live, produce and live in the social system, and is constantly evolving. Aiming at how to comprehensively evaluate the suitability state of a given human settlement environment in a certain time and space and the evolutionary trend of this state, the set pair analysis theory and its partial connection numbers are introduced into the suitability evaluation of human settlements, and the set of human settlements is established. Analyze and evaluate the model and apply it to the suitability status and development trend of human settlements in Jiangxi Province from 2013 to 2016. The results show that the suitability of the province from 2013 to 2016 is between excellent and good, and it is going every year. The direction of more livable development, the intensity of development trend is between 0.5 and 0.53, suggesting that the relevant government decision-making departments need to continuously increase the investment in the livability of the province's human settlements, and ensure that the environmental livability is not weakened.
