The problems of regional resource shortage, fragile ecological environment and unbalanced social development are becoming increasingly serious. There is an urgent need for rational evaluation and planning of resources and the environment. This paper presents a fuzzy comprehensive evaluation method combined with Analytic Hierarchy Process (AHP) and shortcoming element evaluation to analyze the resource and environmental bearing capacity of a certain region. The proposed model was verified by backing data analysis from a karst landscape region in southwest China. Short board element analysis was employed for further study. The results show that (a) the calculation results of the evaluation system used in this paper are consistent with the actual situation. The method can be effectively used in the field of resource and environmental carrying capacity evaluation. (b) The environmental carrying capacity is the largest in this region, followed by the resource carrying capacity, and the socio-economic carrying capacity is the smallest. (c) The region has a sufficient environmental carrying capacity on the whole, the resource conditions are weak and the socio-economic development is backward. The analysis of the evaluation results provides a scientific basis for the rational use of resources, territorial spatial planning, sustainable socio-economic development and ecological environmental protection strategies in karst mountainous areas.
