Dynamic Analysis of Regional Wheat Stripe Rust Environmental Suitability in China

Stripe rust is one of the most destructive wheat diseases in China, negatively affecting production safety and causing yield losses wheat. Thus, it important to analyze environmental suitability dynamic changes stripe China. The occurrence affected by multiple factors. Therefore, this study combined data from various disciplinary fields such as remote sensing, meteorology, biology, plant protection evaluate China using species distribution models. also discusses importance effect variables. Results revealed that meteorological factors had greatest impact on rust, especially temperature precipitation. Wheat growth have a greater April August. Elevation has summer. ensemble model results were better than single model, with TSS AUC 0.851 0.971, respectively. Overlapping analysis showed winter suitable areas mainly Sichuan Basin, Northwestern Hubei, Southern Shaanxi, Henan areas. In spring, increased Huang-Huai-Hai middle lower reaches Yangtze River Guanzhong Plain, development northwestern Xinjiang Gansu slightly lagged behind. summer, threatened late-ripening spring Gansu, Ningxia, Qinghai, Xinjiang. This can provide scientific basis for optimizing improving comprehensive management strategy rust.
