中文摘要:
      为精细化诊断大豆生长季干旱,提高干旱评估的准确性,采用连续无有效降水日数指标来表征干旱,以累积的干旱持续天数将干旱分为5个等级,即无旱、轻旱、中旱、重旱、特旱;并以干旱强度、干旱频率和干旱范围三因子分析1971-2016年间大豆生长季的干旱时空特征。研究表明,1971-2016年间,在大豆生长季,松嫩平原西部的平均干旱强度最强,其中松嫩平原西南部干旱日数超过了90 d,但三江平原东北角和黑河中部干旱强度气候倾向率高于2.5 d·10a-1,有明显的增强趋势,而牡丹江东南部干旱强度气候倾向率低于-2.5 d·10a-1,有较强的减少趋势;松嫩平原西部中度以上干旱频率超过90%,松嫩平原西南部重度以上干旱频率超过50%。1971-2016年中,1976年、1979年、1982年、1989年、1999年、2001年、2004年和2007年约56%~77%的气象观测站点表现为重度以上干旱,长达3个月的时间大豆处于干旱缺水状态,且2007年干旱范围和强度表现最典型。大豆生长季逐日干旱频率动态变化均以“V”形为主要特征,逐日干旱频率从大豆播种出苗期约60%~90%降低至开花结荚期40%以下,但鼓粒-成熟期又上升至40%~80%;从大豆安全性种植角度来评价地域差异,黑龙江省中部好于东部,东部好于西部,西部的北部好于西部的南部。
英文摘要:
      Heilongjiang Province is one of major soybean growing regions in China but drought is a main part of meteorological hazards to its growth, which impact production security of soybean. For precise discriminating drought and enhancing the veracity of drought assessment, drought was studied in Heilongjiang Province based on drought index as continuous days without available precipitation. The drought was divided into five levels such as normal, slight, medium, severe and extreme drought by accumulated days of continuous drought. With these factors such as drought intensity, drought frequency and drought area, spatial-temporal characteristics of drought was analyzed during growing season of soybean. The results showed that center of high drought intensity located in the western Songnen Plain during growing periods of soybean from 1971 to 2016. During that period, the drought intensity was over 90 days in southwestern Songnen Plain, and there was obvious tendency toward increased drought intensity, which climate tendency rate was above 2.5 d·10a-1 in the northeastern Sanjiang Plain and the central part of Heihe region, and there was obvious tendency toward weaken drought intensity, which climate tendency rate was under -2.5 d·10a-1 in the southeastern Mudanjiang region. The medium of drought frequency was above 90% in the western Songnen Plain, and severe drought frequency was above 50% in the southwestern Songnen Plain. In the years such as 1976, 1979, 1982, 1989, 1999, 2001, 2004 and 2007 during the period of 1971 to 2016, drought above severe happened in eighty meteorological observation stations at 56% to 77% and soybean was still in a state of drought and water shortage was for three months. The drought extent and intensity in 2007 were the most typical. Dynamic change of daily drought frequency was characterized by the shape of “V”in growing periods of soybean. From sowing to flowering and podding stages of soybean, daily drought frequency decreased fewer than 40% from 60% to 90%, but daily drought frequency increased to 40% to 80% during emergence stage, again. Therefore, in Heilongjiang Province, as a concerd of soybean production security, the central region is better than the eastern part, and the eastern region is better than the west, and the northern part of the west is better than the southern part of the west.
