摘要
为合理利用气候资源和调整高粱种植品种,利用山西省109个气象观测站1981—2012年标准气候统计资料,建立山西省高粱种植气候区划因子与地理信息的回归模型,确定了山西省高粱种植综合气候区划指标,并利用GIS技术将山西省高粱种植区域划分为早熟、中早熟、中晚熟和晚熟区。分区结果较传统气候区划更直观和精细,为发展高粱产业提供重要技术支撑。
The paper aims to use climate resources rationally and adjust planting varieties of sorghum. The author used standard climate statistics data from 109 meteorological stations in Shanxi Province during 1981- 2012, and established a regression model between information, identified the indicators of comprehensive climate division factors of sorghum and geographic climate division in Shanxi, and also divided the area to early mature area, middle-early mature area, middle-late mature area, late mature area for sorghum planting. The results showed that the division which provided important support for developing sorghum industry was more visual and precise than traditional division.
