| 根据兴安盟重点农区突泉县1961~2006年气象资料和1982~2006年土壤水分资料,采用统计及相关分析方法,分析了近46年来气候变化及其对当地主要农区土壤水分的影响,以及未来气候变化将对土壤水分的可能影响。结果表明,近46年来,内蒙古兴安盟半干旱农区温度呈上升趋势,21世纪以来有加速升温的趋势;降水量变化趋势不明显,存在年代间差异和季节差异,但21世纪以来降水量减少趋势明显;近25年来各季节土壤水分呈下降趋势,并且有加速下降的趋势。环境气象因子对土壤水分的影响以温度和降水量的影响最明显,春季以温度的影响为主,而夏、秋季以降水量的影响为主导。未来气候变化将导致兴安盟半干旱农区土壤水分趋于减少,农业干旱将趋于严重,农业水资源将更加紧张。 |

| Meteorology data from 1961 to 2006 and soil water content from 1982 to 2006 of Tuquan County, an important agricultural area of Xing'an League, were analyzed with statistics and correlation analysis to find out the influence of climate change to soil water content in 46 a in major local agricultural area and the probable influence of future climate change to it.The results indicated that the temperature showed a rising line in 46 a, while precipitation had no obvious change but showed decadal variance and seasonal variance, and the seasonal soil water content showed a declining line in 25 a and declined rapidly in the recent years. Among the environmentally meteorological factors, temperature and precipitation had the most obvious influence on soil water content, and temperature affected mostly in spring while precipitation in summer and autumn.In the semiarid agricultural area of Xing'an League, it may get increasingly dryer in the future, and agricultural drought would be more serious, and agricultural water resources would be more limited. |
