Abstract:
Water resource is an important factor to ensure regional development and a key factor to maintain ecological environment. As an important region in Beijing-Tianjin-Hebei, the water resource carrying capacity of Baoding Plain is of great significance to regional ecology and social and economic development. Based on the basic concept of ecological priority, according to the supply and utilization relationship of different water sources and different water types, the water resource carrying capacity of Baoding Plain was evaluated separately by using the method of combination of quota calculation and linear weighted objective programming, and compared with the local planning, the water resource carrying capacity was classified. The results show that on the basis of guaranteeing ecological water and agricultural irrigation water, under conditions of persistent dry years, total available water of urban life and industrial production will be 463 million m
3 in 2025, lacking of 52 million m
3, and total available water will be 696 million m
3 in 2030, lacking of 56 million m
3. Under conditions of persistent median water years, total available water of urban life and industrial production will be 581 million m
3 in 2025, surplus 66 million m
3, and total available water will be 814 million m
3 in 2030, surplus 62 million m
3. This research can provide scientific basis for development planning in Baoding Plain.
