| 摘 要： | 以辽宁营口灌区为例,考虑作物生育期随气温升高而缩短,研究了气候变化对灌溉需水量影响.结果表明,过去近60年间水稻生育期缩短了12.7 d,下降趋势显著.由于气温上升引起的参考作物腾发量的上升及降水量的下降,不管是否考虑生育期长度变化,灌溉需水量都呈上升趋势.如果不考虑生育期缩短,灌溉需水量呈极显著的上升趋势;如果考虑生...

| Abstract: | This paper investigated impacts of climate change on rice irrigation water requirements of rice with consideration to shortened growing period taking Yingkou Irrigation Area as an example.The results showed that growing period of rice was shortened by 12.7 days during last 60 years and presented a significant decreasing trend.Irrigation water requirements Due to increased temperature induced increase in reference crop evapotranspiration and decreased rainfall,there was an increasing trend in irrigation requ... |
