摘要
通过对以往新疆棉花区划成果的分析,选用≥10℃积温、无霜期、7月平均气温作为阿克苏地区棉花区划指标,采用回归方法建立它们的空间分布模型。利用GIS技术将阿克苏地区分为早熟长绒棉、早中熟陆地棉、早熟陆地棉、特早熟陆地棉四个棉花种植区。
On the basis of the results of the previous cotton regionalizatlon in Xinjiang, selecting the accumulated temperature ≥ 10℃ , frost-free period and average temperature of July as indicators in Akesu region of Xinjian by regional planning the spatial distribution models were estab- lished by using regressive method. Based on GIS, the Akesu region was divided into four cotton planting zones： the premature long-staple cotton area, the premature and mid-mature land cotton area, the premature land cotton area and the extraordinary premature land cotton area.
