山西省主要优势作物的农业气候区划

Agricultural climate zoning for main crops in Shanxi

利用山西省109个气象台站1961~2010年逐日气候观测资料,结合已有粮果作物等的栽培技术与气象条件相关研究等,确定了区划指标,运用GIS技术和小网格推算模型对山西省优势作物进行了区划。区划等级分为适宜种植区、较适宜种植区和不适宜种植区,得到了山西省主要优势作物细线条区划数据集合图集。区划成果对各地（县）的优势作物精细化区划以及调整作物布局提供了较为科学的数据依据。

The daily climate observation data of 109 meteorological offices and stations in Shanxi Province in1961 ~ 2010 were used to determined the Agricultural climatic zoning indices for main crops in Shanxi province combined with the existing fruit crop cultivation technique and meteorological conditions. And the GIS technology was used to zone the suitable area for main crops. The all province could be divided into three zones： most suitable planting areas,more suitable planting areas and unsuitable planting areas. Regionalization results provide more scientific reference for counties to fine division of dominant crops and adjustment of crop distribution.
