| 摘 要： | 收集了50 a(1955～2005)陕西96个气象台站的气温资料,分两个时段(1955-1990和1991-2005)对全省活动积温和有效积温的变化进行了分析,并对冬小麦、水稻、夏玉米、油菜等主要农作物生育期间不同种植适宜区的热量资源的积温两个时段的变化和年际变化特征进行了分析。发现我省主要作物生育期热量资源呈不同程度的增加,但不同作物在不同的种植区其生育期热量资源变化存在差异,特别是在山区和植被较好的地区变化更为复杂,并引起作物生育期长短不均。

| Abstract: | In this paper,the temperature data of 96 observatory stations(branches) for 50a(1955-2005) in Shaanxi were collected.On these base,the variations of the active cumulative temperature and the effective cumulative temperature were studied through analyzing their two intervals,i.e.1955-1990 and 1991-2005.Winter wheat,rice,summer corn and cole were studied during their growing stage for the variation of cumulative temperature of heat sources for the two intervals and annually,respectively,in the different sowin... |
