Abstract:

The optimized allocation of population distribution should not only consider the needs of ecological protection,disaster avoidances and environmental quality,but also should pay attention to the economy power,convenience of transportation and the current situation of regional population.By combining previous study results with characteristics of studied areas,this paper built an index system based on the cell of town and analyzed the spatial disparities of the restriction and suitability level which have influences on the optimized allocation of population by using GIS method.Then this paper comprehensively assessed the suitability level for population growth and distribution in Taizhou City,and divided the studied area into different suitable types for population growth and distribution.This study shows that most of the suitable habitation area of Taizhou includes urban area of the city,counties and some towns close to them and Dainan,Suchen,Huangqiao towns.The comprehensive suitability levels for population distribution in the northern area,like Daying,Hechen,Dazhou towns,are relatively lower,which means the population growth rate should be controlled,and people in these regions should be guided to move to other towns which have lower ecologic restriction level,friendly environmental quality and higher economic attraction for population aggregation.
