基于GIS技术的内蒙古兴安盟春玉米种植气候区划

Climate Division of Spring Maize Based on GIS Technology in Xing'an League,Inner Mongolia

利用兴安盟8个气象观测站及周边相邻省份及地区的18个气象观测站1971—2000年标准气候统计资料,建立了兴安盟玉米种植气候区划因子与地理信息的回归模型,确定了兴安盟地区玉米种植综合气候区划指标,并利用GIS技术将兴安盟玉米种植划分为适宜、较适宜及不适宜种植地区,进行分区评述的同时提出了趋利避害的建议。分区结果对合理利用气候资源,降低玉米产量风险和调整种植业结构具有重要参考意义。

Using standard climate statistics from 8 Meteorological stations in Xing＇an League and 18 meteoro- logical stations in neighboring provinces and regions during 19712000, the authors established a regression model between climate division factors of spring maize and geographic information ,identified the indicators of comprehensive climate division factors in Xing＇an League, and also divided the Xing＇an League to appropri- ate ,more appropriate and inappropriate areas for maize planting, at the same time, the authors made some rec- ommendations to avoid the hazards. Divisional results have an important reference value to the rational use of climate situation, to reduce the risk of maize production and farming structural adjustment.
