Notes: is the planting acreage of user s of the agricultural agent (hm²); is the industrial production value of year n (yuan); and r is the average annual growth rate of the industrial production value (%); is the total number of users of the domestic agent; t is the time variable in the population prediction model (year); a and m are the coefficients to be determined; and k is the given population saturation value of the case study area, which was set to people (Cheng et al. 2015).
