摘要
为合理利用农业气候资源及棉花生产布局提供了科学依据,综合评价了塔里木河流域各县市的棉花种植适宜性,将结果进行分析对比,结合新疆棉花种植的实际情况做出了合理的区划。利用塔里木河流域23个气象站点1993—2012年气候资料,采用DTOPSIS法对塔里木河流域的棉花种植气候资源适宜性进行综合评价,在此基础上结合各县市水资源潜力指数,对塔里木河流域棉花种植适宜性进行区划研究。塔里木河流域棉花种植最适宜区为塔里木河干流区,适宜区大多位于塔里木河中游区及支流地区,次适宜区主要位于下游区及边缘地区,塔里木河流域的较高海拔山区为棉花种植不适宜区。除个别县市外,棉花各生育区内的平均温度和光照时数各县市间相差不大。因此灌溉条件是影响各县市的棉花种植适宜性的主要关键因子。
In order to provide scientific basis for the rational use of agricultural climate resource anddistribution of cotton production, the author made a comprehensive evaluation of cotton cultivation suitabilityin counties around Tarim River Basin and made reasonable regionalization by analyzing the results ofevaluation and considering the actual situation in Xinjiang cotton production. Based on the climate data from23 meteorological stations in Tarim River Basin during 1993—2012, suitability evaluation of cotton planting inTarim River Basin was conducted with the method of DTOPSIS. On this basis, the author researched theregionalization of cotton planting in Tarim River Basin taking into account water potential index of each cityand county. Zoning results showed that the most suitable region for cotton planting was the main stream area,the suitable region included tributaries and middle reaches areas, the sub- suitable region includeddownstream and border areas, and the unsuitable region included mountain area with higher elevation of TarimRiver Basin. There was little difference in average temperature and sunshine hour in cotton planting regions among all counties except individual counties. Thus, irrigation condition was the main impact factor on cottonplanting suitability in each county.
