摘要:

本文介绍了黑河流域的气候概况,分析了近40a流域内以气温和降水为主的气候要素变化,得出黑河流域发生了以“增暖”为主要特征的气候变化。流域生态环境受气候变暖的影响明显,在灾害性天气强度、森林面积、土地荒漠化、湖泊萎缩、草原退化等方面日趋恶化。并就如何保护黑河流域生态环境提出了建议。

关键词: 气候变化, 生态环境影响, 黑河流域

Abstract:

Climate characteristic of Heihe field was introduced in thispaper,the temperature and precipitation change in recent 40 years was analyzed also.  Results showed that Heihe field was changing warmer and its ecological environment was getting worse in strength of damage weather,woods area,soil desertification ,lake diminution andgrassland degradation.  Some suggestions about protecting ecolo乡cal environment of Heihe field were乡ven as well.
