Spatiotemporal Variation of Heat Resources in the Hi River Basin in Recent 51 Years
摘要
Abstract
Based on the data from 10 meteorological stations in the Ili River Basin during the period from 1960 to 2010,the spatiotemporal change of heat resources in this area in recent 51 years were analyzed using the methods of linear regression,T-test and spatial interpolation.The results showed that,spatially,it was richer in heat resources in plain than in the mountainous regions.The mean annual temperature,accumulated temperatures ≥ 0 ℃ and ≥10 ℃ and their durations as well as the frost free period were increased by 0.43 ℃ · (10a)-1,89.9 ℃ · d · (10a)-1,88.0 ℃ · d · (10a)-1,4.0 d · (10a)-1,3.2 d · (10a)-1 and 5.4 d · (10a)-1,equally 2.2 ℃,458.5 ℃ · d,448.8 ℃ · d,20.4 d,16.3 d and 27.5 d,respectively.The variations occurred mostly from the late 1990s.After mutation,the change ranges of the mean annual temperature,duration of temperature ≥0 ℃ and frost free period were the highest in plain but the lowest in the mountainous regions.The change ranges of the accumulated temperature ≥0 ℃ and ≥ 10 ℃ were the most significant in the hilly area but the least in the mountainous regions.The change range of the duration of temperature ≥ 10 ℃ was the highest in the mountainous regions but the least in plain.关键词
