| 摘 要： | 目的]研究旨在为科学、合理地利用当地气候资源,以期为甘肃省河西地区啤酒大麦生产合理规划布局和可持续发展提供科学依据。方法]根据啤酒大麦生长所需的气候条件,并结合前人研究结果,选取年≥0℃积温、幼穗分化期(5月下旬至6月上旬)和灌桨期(6月下旬至7月中旬)的平均温度及年日照时数4项气候要素作为啤酒大麦的气候区划指标,用甘肃河西地区20个气象观测站1981～2010年标准气候统计资料和1:25万地理信息资料, 通过多元回归方法建立了区划因子与地理信息的推算模型, 利用GIS技术和专家评分法,结果]对甘肃省河西地区啤酒大麦进行精细化农业气候区划,分为适宜、次适宜及不适宜3个区域。结论]结果表明,适宜区主要位于沿祁连山北麓一线和马鬃山附近地区12个县(区、市)海拔在1500～2200m之间地区。

| Abstract: | : Objective]Research aimed at use local climatic resources scientificly and rationally, in order to provide a scientific basis for Hexi area of Gansu Province reasonable layout of malting barley production and sustainable development.,method] According malting barley climatic conditions needed for growth, combined with the results of previous studies, Select year≥0℃accumulated temperature, panicle initiation stage (late May to early June) and the average temperature of grain filling period (late June to mid-July), and the number of annual sunshine climate elements as malting barley climate zoning index. Used Hexi region 20 meteorological stations from 1981 to 2010 standard climate statistics and 1:250000 geographic information. Established a division factor and projections model of geographic information by multiple regression method, usingGIS technology and expert scoring method,Results] malting barley of Gansu Hexi areas were refined agro-climatic division, divided into appropriate, second suitable and unsuitable three areas.Conclusion] The results show that suitable areas are mainly located along the north Qilian Mountains and nearby the Mazong Mountain12 counties (districts, cities) above sea level in the region between 1500 to 2200m. |
