[Abstract]:[objective] based on RSGIs technology and intelligent algorithm, the optimal distribution of water in canal system of irrigation area was studied in order to provide scientific basis for improving the management of irrigation area and making water distribution plan. [methods] the working mode of "continuous irrigation between groups, rotation irrigation in group" was adopted. The shortest total water distribution time and the minimum water diversion duration difference between the rotation irrigation groups were selected as the optimization objectives. Taking the two branches of Yingke Irrigation District of Ganzhou District, Zhangye City, Gansu Province as an example, a multi-objective optimal water distribution model was constructed. The model was solved based on particle swarm optimization and ant colony algorithm. [results] the optimal water distribution model of multi-objective canal system was successfully constructed. The case study of the 5km 脳 5km area of Yingke irrigation district in Ganzhou district of middle reaches of Heihe River shows that the optimal distribution of water in the area of Yingke irrigation district in Ganzhou district of Heihe River is an example. The maximum water allocation time and minimum water allocation time were 113.6 h and 105.3 h, respectively, and the difference of water diversion time between rotation irrigation group and rotation irrigation group was 8.3 h, while the maximum water allocation time and minimum water allocation time were 113.5 h and 105.3 h in multi-objective ant colony algorithm, respectively, and the water diversion time difference of rotation irrigation group was 8.2 h. The maximum water distribution time was 113.5 h, the minimum water allocation time was 105.3 h, and the water diversion time of rotation irrigation group was 8.2 h. The results of calculation are lower than those of the original water distribution plan of 168h. [conclusion] solving the water distribution problem of canal system based on RSGIs and intelligent algorithm can not only shorten the cycle of rotation irrigation, reduce the water loss in the process of water distribution, but also ensure the water distribution accuracy. Reduce labor spending.
