沈阳沈北新区蔬菜大棚生产期气候变化及气象灾害对策

目的]研究沈阳沈北新区蔬菜大棚生产期气候变化及气象灾害对策。方法]利用沈阳沈北新区近38年气象观测资料,采用常规数理统计方法,分析沈北新区蔬菜大棚生产期气候变化,并探讨气象灾害天气的应对措施。结果]近38年来,沈北新区光照条件一般,冬季平均日照时数较短（551 h）,呈缓慢减少趋势,但降幅并不明显;沈北新区蔬菜大棚生产期气温倾向率0.371℃/10 a,冬季气温倾向率0.313℃/10 a,气温虽呈升高趋势,但波动幅度较大,让生产管理难以控制;较寒冷期（11～3月）历年降水量、阴天日数呈增加趋势,对蔬菜大棚生产影响较大;低温寡照阴天是该区冬季气候特点,对发展蔬菜大棚产业不利,冬季增加取暖措施有望正常发展。结论]研究结果可为当地设施农业的发展提供科学依据。
