摘  要:
为摸清贵州省黔西南州热量的分布和变化,促进种植业合理布局及气候资源的合理开发,采用5d滑动平均法研究贵州省黔西南州1981—2014年≥10℃积温和积温日数的分布规律与年际变化特征。结果表明:近34年黔西南州≥10℃积温和积温日数均呈上升趋势,趋势性变化达显著水平;≥10℃积温和积温日数从北至南均呈逐渐增加趋势,南部增幅较北部明显,二者的空间分布较一致。≥10℃积温和积温日数变化除贞丰县呈减少趋势外,其余地区均呈增加趋势,其中,望谟县≥10℃积温增加最明显,晴隆县≥10℃积温日数增加最明显。年平均气温升高1℃,则≥10℃积温将增加101.3~503.7℃·d,≥10℃积温日数将延长1.5~20.7d。

摘  要:
The distribution regulation and interannual variation characteristics of≥10℃ accumulated temperature and accumulated temperature days from 1981 to 2014were analyzed by the 5dsliding average method to find out thermal distribution and variation and promote rational distribution of crop farming and rational development of climatic resources in Qianxinan Prefecture,Guizhou.Results:The ≥10℃accumulated temperature and accumulated temperature days from 1981 to 2014present the rising trend and the trend variation reaches the significant level.The ≥10℃ accumulated temperature and accumulated temperature days show a gradual rising trend from north to south and the increase range in south is higher than in north.The spatial distribution of≥10℃ accumulated temperature and accumulated temperature days is no difference.The variation of≥10℃ accumulated temperature and accumulated temperature days presents an increasing trend except for Zhenfeng County. The ≥ 10℃ accumulated temperature significantly increases in Wangmo County and≥10℃accumulated temperature days significantly increases in Qinglong County.When annual average temperature rises 1℃,≥10℃ accumulated temperature will increase 101.3~503.7℃·d and≥10℃ accumulated temperature days will prolong 1.5~20.7d.
