| 摘 要： | 本文利用川西高原21个气象观测站近50年气象观测数据分析了川西高原玉米种植区域的气候资源变化趋势。并基于ARCGIS对川西高原的早、中、晚熟玉米种植进行了农业气候区划。结果表明川西高原玉米种植区域的整体热量资源呈显著的增加趋势,降水资源变化不明显,生产季节内的日照时数呈减少趋势。适宜不同熟性的玉米种植区域主要集中在川西高原的东部、东南部及中部部分地方。

| Abstract: | Based on meteorological data of 21 meteorological stations of western Sichuan plateau during last 50 a, the variation tendency of climate resources for maize planting was analyzing. Furthermore, with the help of GIS technology, the agricultural climate zoning for maize in different maturity periods was proceeding, including earlier-maturity, medium-maturity and late-maturity maize. The results indicated that: In general, the heat resources in maize planting regions of western Sichuan plateau was prone to increase prominently. On the contrary, the precipitation resources had little change, when the sunshine durations had a tendency to reduce in growing seasons. Finally, It was found that the areas being suitable for maize in different maturity periods concentrated principally in the eastern, the southeast and the middle of western Sichuan plateau regions. |
