利用和田地区1961—2006年4个代表站的气候资料,对设施农业主要生产阶段冬季(12月—次年2月)的平均最低气温、浮尘日数、降雪日数、日照时数等气候因子的变化特点进行分析,结果表明:平均最低气温上升,日照时数增加,浮尘日数下降,上述变化对设施农业生产是有利的;但是降雪日数增加,对设施农业生产不利。针对和田地区气候特征,在加大设施农业发展力度,建立南疆特色瓜果蔬菜基地的同时,需要加强雪灾、冷害防御措施。
Based on the climatological data of four representative stations in Hetian from 1961 to 2006, the author analyzed the change of climate factors such as average minimum temperature, days of floating dust, days of snowfall, sunshine hours and so on during the main phases of facility agriculture in winter (December-February) The results show that: the average minimum temperature rise, sunshine hours increase, the number of days of dust fall, the above changes are conducive to the facilities of agricultural production; However, the increasing number of snowfall on the facilities of agricultural production is not conducive. According to the climate characteristics of Hotan region, it is necessary to strengthen snowstorm and chill defensive measures while intensifying the development of facility agriculture and establishing the base of special fruits and vegetables in southern Xinjiang.
