In order to effectively evaluate the environmental carrying capacity of Nanchang city,15 quantifiable indexes are selected to construct the evaluation index system of urban environmental carrying capacity,and the relative residual rate method of environmental carrying capacity is used to evaluate the environmental carrying capacity of the study area from 2008 to 2019.The research results show that：（1） during the period from 2008 to 2019,the comprehensive environmental carrying capacity of Nanchang city showed an upward trend,whose values in 2018 and 2019 were in the loadable state but were in the overloaded state in other yeas;（2）in most years,the relative surplus rate of the criterion layer was less than 0,whose value in resource and environment was under 0 except for 2018 and in social economy was over 0 only in 2017 and 2019,and some indexes were beyond their allowable carrying capacity,but were in the postive trends;（3）the four indicators of per capita water supply,per capita arable land area,water quality compliance rate of monitored sections and urbanization rate developed well.The air quality began to deteriorate in the past two years,and such problems like low forest coverage and inadequate environmental governance occured.On the whole,the resources and environment in Nanchang were not balanced with its development of human society and economy.
