Effect and development mode of transport-driven rural revitalization of"three districts and three prefecture"
Transportation is one of the important driving forces of rural revitalization,and it is of great strategic significance to scientifically evaluate the impact of transportation-driven rural revitalization.In order to consolidate and expand the achievements of poverty alleviation in the"three districts and three prefectures"and effectively connect with rural revitalization,this study takes Nujiang Prefecture as an example,combines multi-source geospatial data and system dynamics(SD)to simulate the development state of transportation-driven rural revitalization,and analyzes the development trend of rural revitalization under four modes of natural growth,rapid transportation development,environmental friendliness and coordinated development by using the rural revitalization index covering economic development,social welfare and ecological environment.The results indicate that:1)For every 5.04％and 2.9％increase in road mileage and residents'transportation consumption level in Nujiang Prefecture,the rural revitalization index increases by 0.03 units,the economic index increases by 0.027 units,the social welfare index increases by 0.0656 units,and the ecological index decreases by 0.018 units.2)The high-speed transportation development model can maximize the economic and social development of Nujiang Prefecture.But it will have a significant negative ecological impact.3)Among all development modes,the coordinated development mode can maximize the rural revitalization index of Nujiang Prefecture.
