摘要:
利用de Martonne干燥度计算方法，计算并分析了20世纪我国干燥度的动态变化。利用GIS软件对计算的结果进行插值计算，并做出了干燥度分布的数字化地图，从而对干旱化趋势进行了探讨。从计算结果看出：我国湿润气候面积在逐步减少，半湿润半干旱气候和干旱气候面积在增大，特别是半湿润半干旱气候面积增幅较大。在20世纪，我国陆地自东南地区到西北地区，气候逐步变的干燥。干旱化的趋势主要是由西北地区和华北地区向南，向东扩展。
Abstract:
We calculated and analyzed the dynamic variation of aridity index in China during the 20th century. The results were interpolated by using GIS software, the digital maps of aridity index distribution were made, and the drought trend was discussed. The results show that humid climate area in China reduced gradually, semi-humid and semi-arid climate areas increased especially, and the arid area increased too. From the southeast to the northwest in China, the climate was gradually drying up in 20th century. The arid area in the northwest and north of China expanded to the south and east.
