Research on Water Resources Carrying Capacity Based on ET
Abstract
With the progress of society, the human demand for water resources is increasing. However, due to the shortage of water resources and the serious water pollution, the contradiction between people and water is becoming more prominent. Therefore, it is necessary to study the water resources carrying capacity. Based on the previous studies, the water resources carrying capacity is defined as a region whose water resources is not beyond the allowable transpiration evaporation and can bear the largest population and the corresponding arable land area in the condition of sustainable development and ensuring the normal material level in this paper, using Weixian as an example. The method of ET was used and the relationship between subject and object was considered; meanwhile, the regional evapotranspiration was defined as the subject and the largest population and the corresponding cultivated land area was the object; and the water resources carrying capacity of different levels in Weixian was calculated.
