Abstract:

In order to improve population capacity of the Yangtze River Delta,this paper aimed to seek some ways to enhance support ability of resources and environment.Based on the experience of international megalopolis,authors of this paper considered that influential factors of population capacity of the Yangtze River Delta are industry assembling scale，resource support ability and environment capacity.According to the result of population project achieved through institution of population and development in Zhejiang University，population will reach 107×108~117×108 in the Yangtze River Delta region in the future.By analyzing support factors of economicpopulation capacity of Yangtze River Delta,it was considered that it is possible for the region to have a population beyond 100 millions，if problems of resource supply and 〖JP2〗environment capacity can be resolved.We also considered that key factors in determining population 〖JP〗capacity in the Yangtze River Delta are levels of land use supply for economic development,supply ability of mineral resources and environment capacity.In order to ensure the stable expansion of population capacity in the region，it is significant to improve safeguard of land use for economic construction by adjusting land use policy at national level,and to strengthen supply ability of strategic mineral resources by establishing the system of oil resources reserve.Meanwhile,the authors suggested that circular economy strategy should be implemented in the Yangtze River Delta region at first.
