Retraction Note: Characteristics of rainfall pattern change in mountainous area based on dynamic adaptive and sustainable development of agricultural tourism

Abstract

The research content of optimal control is to find out the admissible control rules according to the dynamic characteristics of the control system under specific constraints. According to the control object to be executed, the corresponding performance index is optimized. This kind of problem generally exists in the field of technology and practical engineering. In order to solve the optimal control problem, it is necessary to establish a mathematical model describing the motion process of the control object, specify the initial state and target set, give the allowable control range of the control variables, and define the performance index, so as to evaluate the quality of the motion process. According to the analysis of the splash rule of single raindrop on loess, the experiment of increasing rainfall was carried out, and the splash holes were produced around the slope in the first 10 min. With the increase of water, the slope erosion trough is formed due to continuous rainfall, which gradually expands to both sides and develops to the deep, resulting in small-scale collapse on both sides of the trough. With the acceleration of urbanization, ecoagricultural tourism is becoming more and more popular among tourists. Ecoagricultural tourism alleviates the environmental damage caused by over exploitation of tourism resources, makes the new agricultural mode and new business form obtain greater economic benefits, and also makes tourism find a new development path in China. This paper first expounds the background of the development of ecoagricultural tourism and the significance of the topic selection. On the basis of studying a large number of domestic and foreign literature on the development mode and approach of ecoagricultural tourism, it explains the related concepts and theoretical basis of ecoagricultural tourism.
