分析了河西走廊棉花生长发育与气象条件的关系 ,积分回归分析得出皮棉产量与生长期间≥ 10℃积温、8～ 9月平均气温、8～ 9月日照时数呈明显的正相关。以此为区划指标 ,运用模糊聚类方法将河西走廊划分为适宜、次适宜、可种植、不能种植 4个棉花种植气候带 ,用小网格划至乡一级
The relationship between the cotton growth and meteorological conditions in Hexi Corridor was analyzed. The regression analysis showed that the lint yield was positively correlated with the accumulated temperature of ≥ 10 ℃, the average temperature from August to September and the sunshine duration from August to September. Using this as a division index, the fuzzy clustering method was used to divide the Hexi Corridor into suitable, sub-suitable, planted, and can not planted four cotton planting climatic zones with a small grid to the township level
