根据那曲地区气象观测资料以及不同时段牧业生产、经济效益等方面的社会统计资料,分析了近年来该地区气候变化规律、牲畜存栏、牲畜饲养、经济效益收入等状况。在此基础上,讨论了当地气候变化与牧业生产之间的关系。结果表明:那曲地区的气候变化呈现气温增高,降水量、相对湿度、低云量增加,蒸发量、总云量、日照时数减少的趋势;那曲地区牲畜总头数、不同牲畜数量、牦牛出栏数(率)、羊出栏数(率)、仔畜成活数量呈增加趋势,牲畜死亡数呈减少趋势;总收入与牧业收入均有急剧的增长。那曲地区牧业生产与气象要素(最高气温除外)存在着密切联系,即最低气温、降水量、相对湿度、低云量与各牧业要素呈正相关,蒸发量、总云量、日照时数与牧业要素呈负相关。总体来看,气象要素的变化趋势有利于牧业生产,根据气象条件建立的拟合方程基本可以拟合出牧业要素的变化。
According to the meteorological observation data in Nagqu region and the social statistics of animal husbandry production and economic benefits in different periods, the climate change laws, livestock population, livestock raising and economic benefit income are analyzed in recent years. On this basis, we discuss the relationship between local climate change and animal husbandry production. The results showed that the climate change in Naqu showed the trend of increasing temperature, precipitation, relative humidity, low cloud cover, evaporation, total cloud cover and sunshine duration. The total number of heads of livestock, number of different livestock, yak slaughter Number of sheep (rate), the number of slaughter sheep (sheep), the number of live animals showed an increasing trend, the number of livestock deaths decreased; gross income and animal husbandry income both have a sharp increase. There is a close relationship between animal husbandry production and meteorological elements (except for the highest temperature) in Naqu Prefecture, that is, the minimum temperature, precipitation, relative humidity and low cloudiness are positively correlated with the factors of animal husbandry. The evaporation, total cloudiness, sunshine hours and Animal husbandry elements are negatively correlated. Overall, the changing trend of meteorological elements is conducive to animal husbandry production, and the fitting equation established according to meteorological conditions basically can fit the change of animal husbandry elements.
