Abstract

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.
