Abstract： At present， the global energy shortage， environmental pollution and greenhouse effect and other problems are becoming more and more serious. The large-scale development of new clean energy will be the future development trend. the utilization and conversion of solar energy is of great significance to the study of the diversification of aircraft energy supply methods. There is no doubt that UAV detection and monitoring of agriculture and forestry reconnaissance in the Yellow River Delta is more time-saving and labor-saving， simple operation， high speed and high efficiency， while solar aircraft and fixed-wing aircraft have incomparable advantages over other UAVs. Through the design of large aspect ratio， the aircraft in the Yellow River Delta region is designed independently and the load， wing structure and overall layout of the aircraft are continuously improved in order to reduce the induced drag and reduce the vortex at the wing tip. Creatively increase the laying area of solar panels; in order to balance and provide the space for placing panels， the design nose is longer; the Reynolds number is reduced and the efficiency of the propeller is improved; the solar energy is used to convert lithium battery power supply to increase the altitude during navigation. Based on remote sensing and graphic transmission system， data transmission and image acquisition can be carried out for a long time through route planning and design. In real time， the ecological environment pollution and land salinization in the Yellow River Delta will be investigated and monitored for a long time， and a variety of tasks can be carried out flexibly， which will have broad prospects and application scope.
