近57年新疆阿勒泰市农业气候资源变化特征分析

Variation of Agricultural Climate Resources in Altay of Xinjiang Recent 57 Years

摘要: 利用新疆阿勒泰市气象局1961~2017年气温、降水、≥0℃和 ≥ 10℃积温等气候资料，分析了阿勒泰市农业气候资源变化特征。结果表明：近57 a来平均气温表现明显上升趋势，倾向率为0.2℃/10 a；降水量呈逐渐上升趋势，倾向率为15.0 mm/10 a；≥0℃和 ≥ 10℃积温呈现增加趋势。这些变化必将影响到农业生产的布局和结构。

Abstract: Based on the meteorological data of temperature, precipitation, ≥0˚C and ≥10˚C accumulated temperature from Aletai Meteorological Bureau in Xinjiang during the period of 1961-2017; the change climatic characteristics of agroclimatological resources were analyzed. The results showed that the temperature increased remarkable; the climate trend rate was 0.2˚C∙10 a⁻¹; the precipitation decreased rising; the climate trend rate was 15.0 mm∙10 a⁻¹; the accumulated temperature of ≥0˚C and ≥10˚C presented increase trend. These changes will affect layout and structure of the local agricultural production the temperature increased.
