| 摘 要： | 基于晋西北地区8个地面气象站1960~2010年的气象资料及马铃薯生育期平均资料,运用P-M公式,计算了马铃薯生态需水量,分析了生态需水量的时间演变特征及其对气候变化的响应。结果表明:晋西北地区马铃薯生态需水量整体上呈显著下降趋势,但不同时段下降幅度差异较大;风速和日照时数的变化对马铃薯生态需水量的影响最为突出。气候变暖对该地区马铃薯生态需水量的影响表明,气温的升高会增加马铃薯的需水量,且不同地区需水量的增幅不尽相同,气候变暖对寒冷地区马铃薯需水量的影响更加显著。

| Abstract: | Based on the daily data of average temperature,relative humidity,precipitation,wind speed and sunshine duration at 8 me-teorological stations in northwestern of Shanxi Province during 1960-2010 and the growth period data of potatoes,the ecological water requirement of potatoes was calculated using Penman-Monteith equation modified by FAO,firstly.Then,the temporal changes of the ecological water requirement and its response to climate warming were analyzed.The results showed that the ecological water require-ment of potatoes significantly decreased as a whole,while the declining rate in different period was different.The ecological water re-quirement of potatoes was closely related to local meteorological conditions.Compared with other meteorological elements,the variations of wind speed and sunshine duration had more important effects on ecological water requirement of potatoes in northwestern of Shanxi Province,i.e.the decline of wind speed and sunshine duration significantly reduced ecological water requirement of potatoes.The in-fluence of climate warming on ecological water requirement of potatoes showed that the increasing temperature increased the water re-quirement of potatoes,the increase of water requirement in different regions was not completely equivalent,and the impact of climate warming on water requirement in cold regions was more obvious. |
