基于GIS技术的广西苦楝春季物候变化规律研究
Spring phenology variation of Guangxi bead tree (Melia azedarach) based on GIS technology
摘要
Abstract
[Objective]In this study, the phenological changes of bead tree (Melia azedarach) during spring time in Guangxi were analyzed. [Method]By mainly using Guangxi phenological data and conventional meteorological observation data combined with geographic spatial data, the special functions of geographical information system were statistical analyzed. [Result]During various phenological periods in Guangxi, the geographical factors were affected in different degrees. During the nutritional phenological period, the effect of longitude on phenological periods was slightly larger than that of latitude; however, during the reproductive phenological period, the effect of latitude was slightly larger than that of longitude. From the meteorological factor perspective and the geographical factor perspective, the phenological change regulation of bear tree during spring time in Guangxi was analyzed with roughly the same results as this resulting research data. [ Conclusion ] Guangxi bear tree phenological period was postponed from west to east, from south to north, and from plain valley to the mountains. The biggest influencing meteorological factor on phenology of bear tree in spring time was temperature, and the effecting time was mainly concentrated around 1 month to 3 months before phenology.关键词
