【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。更多还原

【Abstract】 On the basis of the results of the previous cotton regionalization 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 established 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.更多还原
