| 摘 要： | 博州（博尔塔拉蒙古自治州的简称）作为北疆暖湿敏感区之一,许多与农事活动有关的气候现象以及风能、太阳能等气候资源发生了变化:≥0℃、≥10℃积温显著增加,主要营养生长期气温升高,延迟性低温冷害强度降低,阶段性低温减少;终霜与10℃活动积温初日提前,初霜与10℃活动积温终日推后;冬暖使得采暖成本降低,蔬菜大棚生产规模扩大,冬作物与牲畜安全越冬得以提高,冬季水电发电量得以保障;博乐市第一场透雨推后,透雨次数减少,干旱化趋势增加,同时山区日降水量达12 mm以上的降水次数增加,洪灾增加;冬季河谷日降水量达3.0 mm以上的中量降雪频次增加,山区稳定积雪期缩短;各地风灾频次减少,年平均风速、年日照时数显著减小、减少。作物营养生产期（5—8月）内,博乐气温日较差显著减小,温泉日照时间显著减少。对农业生产而言,这些气象要素的变化似乎总体利多于弊,对风能、太阳能开发利用而言,则反之。 |

| Abstract: | In Bole region (Bortala Mongolia Autonomous Prefecture for short), one of the sensitive zones to global climate warming and wetting in North Xinjiang, many climate phenomena relating to the agronomic activities and the climatic resources such as wind energy and solar energy etc. had experienced a series of change. The accumulated ≥0℃ and ≥10℃ active temperature increased outstandingly, the mean temperature during the key crop growing period (from May to August) increased. The intensity of delayed low temperature harm weakened and the frequency of phase low temperature reduced. Both the last date of frost and the first date of the 10℃ accumulative active temperature appearing advanced, whereas the first date of frost and the last date of the 10℃ accumulative active temperature appearing delayed. The warm winter has not only reduced the cost for warming air in vegetable canopy and caused a large vegetation production scale, but also enhanced the survival security for the winter crops and domestic animals. In mountainous region, the frequency of wet day with daily precipitation >12.0 mm increased, consequently flood increased. The frequency of snowy day with daily precipitation >3.0 mm increased in Bole valley, but the lasting period of stable snow accumulation shorted in mountainous region. The date of the first soil saturated rain delayed and the frequency of soil saturated rain reduced in Bole, resulting in an enhanced aridity tendency. The frequency of wind disaster reduced significantly, so did the annual mean wind speed and the annual sunshine duration. During the key period of crop growing (May to August), the daily air temperature difference reduced remarkably in Bole, and the sunshine duration decreased in Wenquan. These changes of climatic element over Bole region seem to be beneficial to agricultural production, but disadvantageous to energy development. |
