摘　　要：利用新疆地区及外延200 km范围内173个气象站点1960-2015年逐日气温资料和ANUSPLIN插值软件,综合分析了气候变暖背景下新疆≥10℃的有效积温、无霜冻期和7月平均温度的时空变化特征,并结合地膜增温效应机制,探讨了气候变暖和覆膜对不同熟性棉区种植界限及可种植面积的影响。结果表明:新疆热量资源总体呈增加的趋势,空间分布呈平原和盆地高(多)于山地。气候变暖背景下,中熟棉区、早中熟棉区的种植面积增加,早熟棉区的可种植面积变化不明显,特早熟棉区和不适宜区均减少。地膜增温机制对中熟、特早熟棉区和不宜棉区的种植界限基本无影响,但对准噶尔盆地区域各棉区的种植界限影响显著,其中准噶尔盆地内早中熟棉区东扩65km,早熟棉区东扩范围在0～300 km;地膜增温机制下早中熟Ⅱ叶塔次亚棉区可种植区域增加了5.47×104km2,早熟和特早熟棉区分别减少1.4%和1.6%,但对中熟棉区种植面积基本无影响。研究能为新疆不同熟性棉花的区划和高产提供科学依据。Xinjiang is a main producing area of cotton in China.This study investigated the effects of global warming and plastic mulching on cotton-planting zoning of different matures in Xinjiang.The climatic data were from 173 meteorological stations during 1960-2015 in temperate zone around Xinjiang within a range of 200 km.The digital elevation mode data were from the United States Geological Survey,which had the resolution about 900 m.We analyzed the spatio-temporal variation of accumulated temperature not less than 10℃,frost-free period and mean temperature in July with the aid of ANUSPLIN interpolation software.The cotton-growing area was classified based on these 3 parameters.In addition,the change of planting boundaries and area of different cotton matures were studied with climate change and the compensation effect of plastic mulching.The main results included:1)the accumulated temperature not less than 10℃,frost-free period and mean temperature in July showed an increasing trend in 1960-2015.Regional differences on thermal resources were obvious in Xinjiang.The accumulated temperature not less than 10℃,frost-free period and mean temperature in July were closely related to the terrain elevation.The thermal resources was richer in the southern Xinjiang than those the northern Xinjiang and richer in plain areas than in mountain areas.2)under global warming,the ratio of planting areas of middle mature and early-middle mature cotton all increased.The area of middle mature cotton region increased by 3.82×10^4 km^2,and the main increase areas were located in the eastern part of tarim basin.The increased area of early-middle mature cotton was widely distributed in the eastern Junggar Basin,the southern Turpan Basin,the southern Hami Basin and the western Tarim Basin.But the proportion of planting area of early maturing cotton did not change significantly and exceptional early-mature and unsuitable areas decreased.3)the accumulated temperature not less than 10 oC and mean temperature in July were the main limiting
