在农业的生产发展中,对农作物产量和质量造成影响的关键性因素之一是灾害性天气的发生。灾害性天气不仅影响农业的生产,还可能造成巨大的经济损失,在灾害性天气面前,人们也无法改变。近年来,在全球气候逐渐变暖的状态下,极端天气的发生频率也开始逐年升高,使国家粮食安全受到了极大的威胁。因此,必须加强预防灾害性天气对农民的影响,在预防灾害性天气时,要采取有效措施,利用科学的方法,把灾害性天气发生的特点和类型进行认真评估和分析。基于此,根据农业生产的实际情况,分析湘西的气象灾害,对气象灾害的形成原因和类型作详细说明,为了使湘西的农业现状得到改变,最后提出了对灾害性天气的防御对策,促进农民增产增收。
One of the key factors that affect the yield and quality of crops in the development of agricultural production is the occurrence of catastrophic weather. Severe weather can affect not only agricultural production, but also huge economic losses, and people can not change before catastrophic weather. In recent years, under the condition of gradual warming of the global climate, the frequency of extreme weather has also started to increase year by year, posing a great threat to the national food security. Therefore, it is necessary to strengthen the prevention of the impact of disastrous weather on peasants. In the prevention of disastrous weather, effective measures should be taken to scientifically assess and analyze the characteristics and types of disastrous weather. Based on this, according to the actual situation of agricultural production, we analyzed the meteorological disasters in Xiangxi and explained the causes and types of the meteorological disasters in detail. In order to change the status of agriculture in western Hunan, we put forward the defensive countermeasures to the disastrous weather finally, Increase production and income.
