Variation Characteristics and Influencing Factors of Reference Crop Evapotranspiration in Guangdong Province under Climate Change by HUANG Song, DAI Jiaqi, ZHAO Baoshan, LIU Na, LI Hui, CHU Huaping

“…To explore the temporal and spatial variation characteristics of reference crop evapotranspiration (ET₀) in Guangdong Province under climate change and its influencing factors,based on the surface observation data of 37 meteorological stations in Guangdong Province during 1980—2020,the FAO-56 Penman-Monteith method was applied to calculate the daily ET₀ of each meteorological station.In addition,this research systematically analyzed the temporal and spatial variation characteristics of ET₀ in Guangdong Province and quantitatively studied the influence degree of various meteorological factors on ET₀ by using sensitivity and contribution rate analysis methods.The results show that in terms of time scale,the annual average ET₀ in Guangdong Province is 1 150 mm,and it shows a significant increasing trend at the rate of 14.84 mm/10a.In terms of spatial scale,ET₀ in Guangdong Province shows an increasing trend from north to south,with a variation range of 1 069~1 235 mm.ET₀ is more sensitive to relative humidity and temperature than sunshine duration and wind speed.The contribution rate analysis shows that temperature is the dominant factor for ET₀ variation in Guangdong Province,followed by sunshine duration,relative humidity,and wind speed.The potential increase in temperature combined with the decrease in relative humidity can lead to higher ET₀ and drought events in the future.This study can provide a scientific basis for water resources planning and agricultural irrigation management in Guangdong Province.…”

Robust reinforcement learning algorithm based on pigeon-inspired optimization by Mingying ZHANG, Bing HUA, Yuguang ZHANG, Haidong LI, Mohong ZHENG

“…Reinforcement learning(RL) is an artificial intelligence algorithm with the advantages of clear calculation logic and easy expansion of the model.Through interacting with the environment and maximizing value functions on the premise of obtaining little or no prior information, RL can optimize the performance of strategies and effectively reduce the complexity caused by physical models .The RL algorithm based on strategy gradient has been successfully applied in many fields such as intelligent image recognition, robot control and path planning for automatic driving.However, the highly sampling-dependent characteristics of RL determine that the training process needs a large number of samples to converge, and the accuracy of decision making is easily affected by slight interference that does not match with the simulation environment.Especially when RL is applied to the control field, it is difficult to prove the stability of the algorithm because the convergence of the algorithm cannot be guaranteed.Considering that swarm intelligence algorithm can solve complex problems through group cooperation and has the characteristics of self-organization and strong stability, it is an effective way to be used for improving the stability of RL model.The pigeon-inspired optimization algorithm in swarm intelligence was combined to improve RL based on strategy gradient.A RL algorithm based on pigeon-inspired optimization was proposed to solve the strategy gradient in order to maximize long-term future rewards.Adaptive function of pigeon-inspired optimization algorithm and RL were combined to estimate the advantages and disadvantages of strategies, avoid solving into an infinite loop, and improve the stability of the algorithm.A nonlinear two-wheel inverted pendulum robot control system was selected for simulation verification.The simulation results show that the RL algorithm based on pigeon-inspired optimization can improve the robustness of the system, reduce the computational cost, and reduce the algorithm’s dependence on the sample database.…”
