土地承载力与城市建设之间存在密切的联系。本文首先阐明昭通盆地城市建设层稳定性，在此基础上对昭通盆地的土地承载力就人口增长预测和农产品产量预测两方面进行估算，然后分别就昭通盆地对昭通市区承载力和市区内部土地承载力进行分析，在可预见的社会经济发展水平下能持续供养的人口数量，最后确定城市适宜性发展的方向。 There is a close relationship between land carrying capacity and urban construction. In this paper, firstly, the stability of urban construction layer in Zhaotong Basin is clarified. On the basis of this, the land carrying capacity of Zhaotong Basin is estimated on the basis of population growth forecast and agricultural product yield forecast. Then, the paper compares Zhaotong Basin’s bearing capacity with urban area The carrying capacity of land, the population that can be sustainably supplied under the foreseeable level of social and economic development, and finally the direction of urban suitability development.
