This paper, based on expert effect formula establishing expert subjective assessment matrix, uses entropy weighting to give objective and subjective weights of indicators, and presents multiple expert comprehensive assessment of carrying capacity of resources and environment on the basis of weights integrated model that is established by the minimum cross entropy. This method, without any added information, combines subjective with objective weights, which avoids not only the subjective random, but also the excessive information from data. This paper, from subsystems economy, population, natural resources and environment, sets up comprehensive evaluation index system of carrying capacity of resources and environment which is used in Guangxis Beibu Gulf city agglomeration. The results show Nanning has a rapid growth with big population and GDP; Beihai has a rising GDP thanks to its coastal locality; Qinzhou and Fangchenggang ranks at bottom, which need to consider how to consolidate resources and increase urban comprehensive intensity. The study is consistent with the actual, which validates the method.
