| 摘 要： | 气候变化会引起农业气候资源的变化，气候资源的变化又会导致作物生育期长短的变化。通过分析１９８０年以来湖北省几种主要农作物生育期间积温的变化，发现不同作物生育期间热量资源的变化在不同的地理位置存在明显差异，并因此引起作物生育期长短不均。山区热量资源以减少为主，作物生育期将延长；平原地区热量资源以增加为主，作物生育期将缩短。

| Abstract: | Climate variation results in the change of agriculturally climatic resources and their variation affects the change in the crop growth period (CGP). This paper investigates the variation in accumulated temperature for main crop growth from 1980 in this province, discovering differences of the thermal variation during a range of CGP on a geographical basis. It is found that the decreasing (increasing) thermal resources will cause prolonged (reduced) CGP in mountains (plains). |
