| 摘 要： | 利用EOF等方法通过计算1971-2000年30年来云南三江并流地区6个气象台站气温、降水、蒸发资料，分析了云南三江并流地区近30年来气候变化的异常特征及其对生态环境的影响，结果表明：云南三江并流地区气候变化表现为气温升高、降水略有减少和蒸发增大的干旱化气候变化趋势，同时，在气候干旱化和人为活动的影响下出现草场退化、冰川萎缩、雪线上升、土壤沙化和水土流失等生态环境荒漠化问题。 |

| Abstract: | Based on the data of air temperature, precipitation and evaporation at 6 meteorological stations over the three-river-area in Yunnan from 1971 to 2000, the abnormal characters of climate changes in 30 years and its effect on ecological environment were analyzed by using statistical methods such as EOF. The results showed that air temperature and evaporation appeared to have been increasing and precipitation reducing in the region. At the same time, arid climate and artificial activity resulted in the hungriness of ecological environment such as degenerating of the pastures, shrinking of the iceberg, increasing of the snowbanks, deserting and losing of water and soil as well. |
| Keywords: | climate change ecological environment hungriness |
