摘要:

利用甘肃省河西地区3条主要内陆河昌马河、黑河、西营河流量以及酒泉、张掖、武威3个地区的春小麦产量资料,分析了甘肃省河西地区内陆河流量对河西地区春小麦产量的影响。结果表明:河西的粮食产量除了受灌溉水利发展、农业技术和优良品种等生产力水平提高,呈现波动上升趋势外,还受到灌溉水源的影响。春季径流的差异会导致春小麦单产的明显年际波动。年径流短期波动对产量影响较小,但径流长期波动的影响要大于短期波动,特别是春季径流的长期趋势决定着调节水库的蓄水量多寡,这在一定程度上反映出目前的农业生产仍受气候变化的影响。

Abstract:

By using the data of monthly surface runoff of Shule,Heihe and Xiying rivers,and spring wheat yields in Zhangye,Jiuquan
and Wuwei regions more than 40 years,the impacts of the surface runoff of inland rivers on the spring wheat yields in Hexi region
were analyzed.The results show that the spring wheat yieldis increasing fluctuatly due to the development of irrigation,agricultural
technology and improved variety,additionally,it’s also impacted by the source of irrigation.The difference of runoff in spring could
lead to annual fluctuation of spring wheat yield,short-term fluctuation of annual runoff impacts on yield is small butlong-term
fluctuation is larger,especially the long tendency of runoff in spring decides measuring the amount of water inreservoirs,so it shows
that agricultural production is impacted by climate change.

Key words: surface runoff of inland river, spring wheat yield, influence
