The Impact of Highway on the Population Distribution a Case Study of Henan Province (2004-2016)

Abstract

Population migration is not only affected by people's living habits, economic development status, the city's geographical location in the region, and regional traffic facilitation also plays an important role. In order to fully study the impact of highway on the regional population change, the paper designs an intercity population impact index and a city population change type index by using the intercity accessibility as the weights. The results show that, during the period of 2004-2016, the population of Henan province has been growing steadily, the outflow of population was serious, and there are significant differences in the characteristics of resident population change among cities. The response sensitivity of city resident population is proportional to the highway mileage increase, the responsiveness has significant difference among cities, the responsiveness of the developed areas are relatively low, and the responsiveness of the marginal areas is obviously higher than that of the central areas. The traffic population input type cities are mainly distributed in the southwest of the province, where has good natural living environment, the city in the central of province has the characteristics of traffic population output type. The changes of city total population spatial distribution tend to be balanced, the city resident population spatial distribution changes greatly, the impact of the highway on the province's population migration tends to be balanced.
