摘要： 本文用较新的资料,研究了宁夏气温的空间变化规律、数学模拟以及气温的多年变化特征。结果表明:宁夏气温在地区分布上呈现南低北高的地域分异规律;用海拔高度、地理纬度、经度模拟当地气温的空间分布,具有很高的精度;宁夏气温多年变化普遍存在着10-12年及2.2-2.5年的变化周期。

关键词: 气温, 数学模拟, 功率谱, 宁夏

Abstract: In this paper,we studied the spatial and temporal changes in temperature in Ningxia.The results are that the temperature in the south is lower than that in the north in Ningxia.The exactitude of reckoning temperature by using height,latitude and longitude is very good.The year-to-year change of temperature has 10-12 year and 2.2-2.5 year cycles.

Key words: Temperature, Mathematical modelling, Power spectrum, Ningxia
