| 摘 要： | 利用金塔、敦煌和额济纳旗三站十年的风、温、降水场常规气象资料,通过归类统计,对比分析了不同类型(旺盛的、稳定的和退化的)绿洲夏季三个月十年月平均温度、降水和风场的特征差异及变化。结果表明,不同类型绿洲的局地气候差异很大。退化绿洲和旺盛绿洲相比,月平均温度高1～2℃;风速大1～1.5m/s;而降水量则明显少于旺盛绿洲。这种干燥、大风、少雨的气候特点严重影响了当地居民的生产、生活,也制约了当地经济的可持续发展。因此加强对退化绿洲的治理和保护,迫在眉睫。

| Abstract: | Ten years of wind, temperatureand precipitation routine weather data of Jinta, Dunhuang and Ejina 3 stations were analyzed by Pass classify Stat.,the characteristics diversity and changes of ten years of month wind speed, temperature and precipitation over different types (hearty, steady and degraded) of oasis in three months of summer were compared. The results showed that different type oasis'local climate have remarkable diversity. The monthly temperature of degraded oasis was 1~2 oC higher than that in undegraded oasis ; wind speed increase1~1.5m/s; but the precipitation was obviously less than that of undegraded oasis. This kinds of dry, blustery and rainless climate seriously influenced the living and production of the population, also limitated the sustainable development of economy in this area. |
