Assessing Soil Water Resources Carrying Capacity of Cultivated Land in Hebei Province Using a Variable Fuzzy Model

In this study, the concept of soil water resources carrying capacity of cultivated land is defined, the status of soil water resources in Hebei Province is analyzed. To evaluate the utilization of soil water resources of cultivated land and to use it rationally and scientifically, the assessment index system of soil water resources carrying capacity of cultivated land is established and the variable fuzzy model is used to assess the carrying capacity in this province in 2030. The assessment results show that the carrying capacity grade is the second grade, i.e., "Plan is average and can adapt to the local agricultural development" and indicate that soil water resources can basically meet the development of the local agricultural economy, while a rational development scale must be determined in Hebei Province.
