中文摘要: 秦岭作为我国地理分界线和气候过渡带,对气候变化敏感,研究其水热条件变化对因地制宜发展本区水稻,保障该区水稻稳定生产具有重要意义.基于1960 - 2016年秦岭南部37个气象站点逐日观测数据,通过线性趋势估计、气候倾向率、空间插值等分析方法,研究秦岭南部一季稻生长季内水热条件时空变化特征,结果表明: ①近57年秦岭南部热量资源呈增加趋势,水资源和光资源呈减少趋势;特别是1988年以来研究区升温更为明显,以暖干气候特征为主,但有向暖湿变化的趋势,光照条件相对改善.②秦岭南部一季稻生长季平均气温和≥10 ℃积温多年平均值自南向北递减分布,高温热害强度( 7 - 8月)自西南向东北递减,日较差自中部向东西部减少;生长季降水量自南向北减少,穗分化期降水量自西向东呈多-少-多分布,干燥指数自西南向东北递增;生长季日照时数自西南向东北递增,结实期日照时数自西向东递增.③秦岭南部一季稻生长季平均气温和≥10 ℃积温高值区增幅较小,低值区增幅较大,西部受高温热害强度较大,日较差低值区趋于减少,高值区趋于增加;生长季和穗分化期的降水量空间倾向率变化复杂,整体上多雨区趋于干旱,少雨区趋于湿润,干燥指数空间倾向率东部在降低,西部在升高;光照条件空间倾向率均表现为减少趋势.综合以上分析结果对秦岭南部一季稻耕作具有一定的实践指导价值.
英文摘要: The research of Qinling's climatic condition variations is significant for the development of rice based on local conditions and the guarantee for stable rice production,because the Qinling,one of geographical boundaries and climate transition zones in China,is sensitive to climate changes. Based on daily data of 37 meteorological stations in the south of the Qinling Mountains from 1960 to 2016 and the methods of linear trend,climatic trend rate and spatial interpolation,the paper researched temporal and spatial variations of climatic conditions during the growth period of single-season rice. The results are as follows: ① The heat resources tended to increase,the water and light resources tended to decrease in the past 57 years in the south of the Qinling Mountains. Especially since 1988,the temperature has become obviously higher and the climate has become warm and wet,and the lighting conditions have been relatively improved. ②The average temperature and ≥10 ℃ accumulated temperature and the precipitation gradually reduced from south to north in the study area. The heat injure intensity ( in July and August) gradually reduced from southwest to northeast,the drying index and sunshine hours were contrary to it. The diurnal range gradually reduced and the precipitation in the spike differentiation period increased from center to east and west. The sunshine hours of the fructicative period gradually increased from west to east. ③ There were a small increment of the high value region of the average temperature and ≥10 ℃ accumulated temperature and a large increment of the low value region. The heat injure intensity was higher in the west of the study area. There were a smaller decrement of the low value region of the diurnal range and a large increment of the high value region. The spatial variation of precipitation was complicated, the rainy areas tended to be dry and the less rainy areas tended to be moist. The climatic trend rate of the dry index decreased in the east while rised in the west. The climatic trend rate of the light conditions decreased. The above results have a practical guiding value for the single-season rice cultivation in the south of the Qinling Mountains.
