Abstract:  The planning of the main functional zones is the basis of the development and rational utilization of land space, and the study of the rural regional functional pattern under the different functional areas is a new perspective to explore the diversified development of rural areas and to realize the revitalization of rural areas. Taking the rural area of Baoding City as the research area, this study constructed the functions evaluation index system of rural area based on the perspective of the main function area, and realized the rural area functional division using entropy weight method and repeated dichotomy method. Also, it explored the influencing factors of each index layer by using the obstacle diagnosis model. The results showed that the high value of agricultural production function was concentrated in the east and Southern Downs Region of the research area, the high value of industrial production function was distributed around the central towns, and the high value of life support function was distributed around the Central County.The high value of cultural tourism function was concentrated in the middle area of the north, while the high value of ecological conservation function was mainly distributed in the mountainous area of the northwest of the study area. Also,based on the main function area, the research area was divided into 11 Class II function zones, whereby the main production zone of agricultural products was divided into the key industrial development zone, key agricultural production zone, agricultural productiontrade service zone, and agricultural productionlife guarantee zone. The key development zone included agricultural productionindustrial development zone, key cultural tourism zone, and agricultural productionecological conservation zone. The key ecological function zone included the key ecological conservation zone and the ecological agriculture production zone. Lastly, the main obstacle factors in the study area included the average effective soil layer thickness of cultivated land, reclamation coefficient, mileage of provincial and county highway, mileage of street road and the coverage ratio of river basin. This shows that the rural areas in Baoding still have the problems of low quality of arable land and inadequate infrastructure.
