#$%^&*AU2019101466A420200116.pdf#####ABSTRACT The present invention provides a quantification method for urban space coordinated development based on a difference of relative development rates between cities and in consideration of a spatial synergic relationship. In the present invention, a total urban permanent population, an urban built-up area, urban secondary and tertiary industries are endowed with weights, and formulas for calculating index change rates of the total urban permanent population, the urban built-up area, and the urban secondary and tertiary industries are used to improve a US-PLE evaluation model. Finally, a result obtained by dividing a difference of development rates between cities by a distance between the between cities is used to express a development index S of a city relative to another city; a sum of all S in a region, and whether an S value is positive or negative, to obtain an expansion mode that the city should adopt in a condition of considering the space synergy. Finally, reasonable prediction for future urban area planning of the city can be conducted by using a proportion of an S value in the sum.DRAWINGS Collect data nation secondary and daaArea data tertiary industries) dada CalcCalculatearelative Calule aevpopulatio Calculate an urban land-use rCalculate an urban economic sizedeelopment scale development speed development speed Construct a Chmna's urban scale structure index evaluation model |Calculate a relative development index S B represents a ratio of an S value of a Determine, based on whether an county (city) to a sum of S values of S value is positive or negative, counties (cities) in a region to adopt increment/stock/ deer t deve pment F=B*Ae Futr urban area plannm FIG1 1 1
