基于GIS技术对玉米种植精细化综合区划

Fine Agricultural Regionalization of Maize Planting Based on GIS

利用山东省泰安市岱岳区气象局及各乡镇区域气象观测站气象数据,结合地形因子和土壤因子空间分布特征,确定了岱岳区玉米种植综合气候区划指标,并利用GIS技术将该区玉米种植划分为适宜、较适宜及不适宜种植地区。结果表明,岱岳区绝大部分乡镇均为玉米种植的较适宜区,不适宜种植玉米的地区位于徂徕镇及化马湾西部、良庄镇东北部,最适宜区位于山口镇。分区结果可为合理利用气候资源,降低风险和调整种植业结构提供参考。

Based on the data of meteorological bureau and various meteorologi- cal stations of rural areas in Daiyue District, Tai＇an City in Shandong Province, the integrated climatic regionalization indicators of maize had been determined in combination with spatial distribution features of terrain and soil factors. The maize planting area in Daiyue was divided to three regions by using GIS technology, which were suitable zone, subsuitable zone and unsuitable zone. Results showed that the major towns in Daiyue District was the subsuitable zones for maize planting except Culai, west area of Huamawan and northeast area of Liangzhuang were the unsuitable zones for maize planting, and the most suitable areas were located in Shankou Town. The division results could provide reference for the rational use of climate resources, the risk reduction and the plantation structure adjustment.
