气候变化对人民胜利渠灌区作物灌溉需水量影响分析
Impact of Climate Change on Irrigation Water Requirement of Crops in People's Victory Canal Irrigation District
摘要
Abstract
Using Meteorological data of People's Victory Canal Irrigation District in recent 52 years,the change and their correlation of major crop water requirements,irrigation water demands and meteorological elements in correspondding growth period were analyzed.Results showed that:water requirements of rice,corn,cotton and peanut decreased significantly while water demands of wheat and oilseed increased indistinctively.Changes of all crops irrigation water demands were not significant.The key factors of crop water requirement were sunshine hours (for rice,corn,cotton and peanut;positive correlation),average relative humidity (for wheat and cole; negative correlation) ;Rainfall was the main factor and was negatively correlative with crop irrigation water demand.关键词
