Simulation and Analysis of Agricultural Irrigation in Haihe Basin
Researches on regional agricultural irrigation and its trend are becoming more and more important for the great impacts of human activities on water cycle. The paper calculates the reference crop evapotranspiration of each district in Haihe basin based on Penman-Monteith Formula, and processes of agricultural irrigation of main crops are simulated. According to the research, with the remarkable rise of mean atmosphere temperature and prevalent falling of sunlight duration, relative humidity and wind speed in Haihe basin, the reference crop evapotranspiration of whole basin is decreasing, while trends of each district differ a lot. The simulations of daily agricultural irrigation are supposed to provide water consumption of agriculture to distributed hydrological model based on dualistic water cycle, which is very meaningful for the simulation of water cycle under high-intensity human activities.
