摘　　要：热量是农作物生长发育极其重要的环境条件,直接影响农作物种植区域及生长发育的速度、成熟早晚、产量高低和质量优劣[1]。≥10℃活动积温是热量资源的一项指标,与农作物生长发育关系最为密切,受其经、纬度、海拔高度和大地构造地貌单元的影响,≥10℃积温在新疆西天山有较明显的区域分布,因此,分析研究≥10℃积温的时空变化,不仅有助于进一步认识西天山热量分布和变动情况,而且对于作物及其品种的合理布局、气候资源的合理开发和利用等均有直接的实际意义。A systematic study was conducted on quality of heat which has direct influence on crops growth and development in agricultural area, conceming mature period, crop yield and quality. The ≥10℃ accumulated temperature is an index of heat resources which has great relation to growth and development of crops, which is influenced by longitude, latitude, height above sea level and the earth construction physiognomy unit. There is ohvicus area distribution character of ≥10℃ accumulated temperature. The study on space - time variation of ≥10℃ accumulated temperature not only can help to reveal the heat distribution and variation in Western Tianshan Mountain of Xinjiang, but also provide actual suggestions for reasonal development and utilization of climatic resource and rational distribution of different crops and varieties.
