黑龙江省热量资源时空变化特征研究

为给黑龙江省合理开发利用热量资源提供科学依据，基于黑龙江省1961—2017 年79 个观测站的逐日气温资料和DEM数据，采用5 日滑动平均法、一元线性回归法、Kendall-Theil 线性趋势估计法以及GIS的空间分析技术，探讨了黑龙江省热量资源时空变化特征。结果表明：1961—2017 年黑龙江省稳定通过10℃积温以27~101℃·d/10 a 的趋势显著增加。小兴安岭北部从黑河、孙吴到逊克，再到嘉荫一带，平均气温增加趋势明显大于大兴安岭地区的漠河和塔河以及三江平原的大部分区域。最低平均气温呈显著上升趋势，平均气温次之，最高平均气温的线性趋势无显著变化；冬季最低平均气温上升趋势明显高于夏季。松嫩平原及三江平原地区的热量资源较为丰富，大小兴安岭及张广才岭山区等地区热量资源相对较差。

Heat Resources in Heilongjiang: Spatio-temporal Characteristics

To provide a basis for the rational development and utilization of heat resources in Heilongjiang, based on daily air temperature data and DEM data from 79 observations during 1961-2017, we analyzed the spatio-temporal variation characteristics of heat resources by adopting 5-day sliding average method, lineartrend estimate, the Kendall-Theil method and GIS. The results showed that: the accumulated temperature steadily above 10℃ in Heilongjiang during 1961- 2017 increased significantly by 27- 101℃ · d/10 a; the increasing trend in the north of the Lesser Khingan mountains (from Heihe, Wusun to Xunke, Jiayin) was greater than that in Mohe, Tahe of the Great Khingan mountains and most of the Sanjiang plain. The lowest average temperature showed a significant upward trend, the average temperature was the second, the linear trend of the highest average temperature did not change significantly; and the rising trend of the lowest average temperature in winter was significantly higher than that in summer. Heat resources are generally rich in the Songnen plain and Sanjiang plain, and poor in the Great Khingan mountains, the Lesser Khingan mountains and Zhangguangcai mountains.
