摘要
利用地层沉积物孢粉分析成果和相关文献记载复原一万年以来凉山地区的气候状况,并分析了历史时期凉山地区气候变迁的规律:凉山地区一万年以来气候变化大致可分为8个时期,其间气候有冷暖干湿的变化,气温的变化幅度在1℃～2℃,垂直气候带有上升和下降的变化,升降幅度在200～400m之间。一万年以来凉山地区气候变化的总体趋势与内地大体一致,但在具体时段上有一定差异,气温虽有冷暖的变化,但总体上气温比内地略为温暖。
The article restored the climate situation of Liangshan moutain areas by using the reports of the analysis of sporogonia in geologic stratas and related cultural heritages,then analyzed the regulations of climate change in history period in these areas： The climate changes can be divided into eight periods since 20,000 yearses be- fore,while temperature and humidity were all changed in different periods; Temperature changed within 1℃ to 2℃; The perpendicular climatic zone contained rising and descendent varieties from 200 to 400 meters. The trend of climate changes in Liangshan moutain areas was the same with the climate change of China,but the time of every priod was different,and the temperature was manner than hinterland.
