【摘要】 利用京、津、冀区域内1961-2000年70个气象观测站点的逐日平均气温记录,分析研究了河北省1961-2000年气候生长期的变化趋势。结果表明,在近40a中,气候生长期在全省范围平均增加了15.0d,冀北高原区5.4d,燕山丘陵区5.9d,冀东平原区21.3d,太行山区12.6d,山前平原区22.9d,全省及各区域生长期的变化均呈增加趋势。20世纪90年代是气候生长期增长最明显的时期。对气候生长期变化趋势空间分布特点的进一步分析表明,山前平原区、冀东平原区是气候生长期增长趋势最明显的地区。更多还原

【Abstract】 Decadal variation and change tendency in temperature-defined growing season over the past 40 years were analyzed using daily tem- perature data of 70 meteorological stations in Beijing,Tianjin and Hehei region from 1961 to 2000. The results showed that growing season in- creased 15.0 days in Hebei region,5.4 days in the ahiplano in north Hebei,and 5.9 days in the areas of Yanshan hill,21.3 days in the plain in east Hebei,12.6 days in the area of Taihang Mountain,and 22.9 days in the plain in front of the mountain. Growing season of the whole prov- ince and its different region trended rising up. The most rapid increasing of growing season occurred in the 1990s. Based on analysis of spatial distribution of growing season change tendency,the most obvious increasing trend of growing season was found in plain in front of the mountain and nlain in east Hebei.更多还原
