摘要: 使用2009—2013年的CLDAS大气驱动场(V1.0)数据为气候数据源,结合影响西藏青稞种植的关键气候因子,确定生育期≥0℃的积温(T0)、最热月平均气温(Tmax)、生育期降水量(R)这3个气候因子作为西藏青稞种植区划指标,利用GIS技术进行西藏青稞种植气候适应性区划。为了得到既能满足气候需求又有耕地的实际可种植区域,本研究将土地资源信息与气候区划叠加。结果表明:青稞最适宜种植区域主要分布于雅江中游河谷2400~4100 m区域及昌都市的中部和南部,结果与事实相符。

Abstract: Using CMA Land Data Assimilaton System Version 1.0(CLDAS V1.0) from 2009-2013 as climate data source, Combining with the key climate factors that affects the Tibet highland barley planting, three climatic factors including ≥0℃ accumulated temperature during highland barley growth,average temperature of the most month, precipitation during highland barley growth were chosen as the indices of highland barley—planting regionalization, By using GIS-spatial analyst technology,the regionalization of the climate suitability in highland barley -planting in Tibet Was conducted.After superposed landuse information on the climatic regionalization,the highland barley—planting areas which could both satisfy climatic demand and satisfy practically suitable farmland were determined.The results showed that the most suitable planting area of highland barley was Yu Yajiang middle river valley area and central and southern of Qamdo. The result is consistent with the fact.
