以山西寿阳县的玉米和小麦为研究对象,应用尺度推绎方法开展机械化与传统耕作方式下区域粮食作物耕作适宜性的对比研究。结果表明:(1)传统耕作方式下玉米与小麦适宜种植面积皆要大于机械化耕作方式下2种作物适宜种植面积,而无论是机械化种植还是传统耕作小麦适宜种植区面积皆大于玉米种植适宜区;(2)2种作物种植适宜区空间分布呈两极化特征,即高度适宜区与永久非适宜区占据研究区绝大部分区域;(3)2种粮食作物高度种植适宜区基本集中在寿阳县北部黄土高原的塬、沟地貌区及坡度较小的山区。建议在机械化种植与传统耕作方式下皆是中、高度种植适宜区域采取机械化种植方式,而在仅适宜传统耕作的种植适宜区采取传统方式耕作。
Taking maize and wheat in Shouyang County of Shanxi as the research object, a comparative study on suitability of regional grain crops under mechanization and traditional tillage was carried out using the standard deduction method. The results showed that: (1) The suitable planting area of maize and wheat under the traditional tillage method was larger than the suitable planting area of the two crops under mechanized tillage, while the suitable planting area of both mechanized planting and traditional tillage was larger than that of maize planting. (2) The spatial distribution of suitable planting area of the two kinds of crops is bi-polar, that is, highly suitable area and permanent non-suitable area occupy most of the study area. (3) The suitable planting areas for the two kinds of food crops are basically concentrated in Shouyang County Plateau in the northern loess plateau, gully area and slope of smaller mountainous areas. It is suggested that mechanized planting should be adopted in moderately and highly suitable planting areas under both mechanized and traditional tillage modes while conventional cultivation should be adopted in suitable planting areas suitable only for traditional tillage.
