Climate change refers to changes in long-term climatic characteristics and may lead to exacerbation of short-term climate variability and extreme climate frequency, resulting in a disastrous environment resulting from changes in the biological growth environment on earth. In recent years, the impact of changes in climate and environment has led to an increase in the frequency of extreme events and the widening disparity in precipitation and rainfall caused by the unstable hydrological and meteorological conditions. Climatic, hydrological and environmental constraints coupled with the growth in water demand in the future are increasing the dilemma of regional water supply. In addition, the issue of food is also an important issue on a global scale. How to establish an appropriate paddy field irrigation operation and management method to ensure the effective use of agricultural production and water resources and an important issue of water resources planning in the future? Irrigated water in the area is obviously seasonally dry. Therefore, if the rainfall in the rainy season in the second half of the year is not as expected, it will most likely cause water shortage in the first phase of rice in the next year. This year, we evaluated and adjusted the cultivation schedule and farming system in the northern part of the Hsinchu, Taoyuan, and Taipei area for seasonal drought, and used the system power model to show the characteristics of the dynamic behavior of the system over time and establish a water mode for field water balance. Based on the hydrological balance of payments method, establish the correlation between the control system of the field in the study area and the water use factors in each field, and establish a regional water allocation model to explore the water use situation in various scenarios after the adjustment of the cropping period. Through the adjustment of the planting period of rice, the coordination mechanism and specific operations of water resources allocation will be discussed, and the adjustment strategy for assessing water resources under the adjustment of irrigation period will be completed.
