成都东部山丘区气候变化与生态现状对策研究

利用1959—2008年成都东部地区金堂县、双流县、新都县的气温、降水资料，用距平、累积距平、线性趋势分析了成都东部地区气温、降水的时空变化特征，并用滑动-t检验与MK检验分析了成都东部地区气温与降水的突变特征。结果显示：近50年来，成都东部地区气温明显升高，降水总体呈减少趋势，成都东部气候呈现暖干趋势。同时对成都市5个温度区进行温度湿度和绿化率关联分析，结果证明，无论是平均温度还是最高温度均随相应区域内绿地率、绿地覆盖率的增大而随之降低；而相对湿度随之升高。可见，增大绿化面积的旷达对环境降温增湿的作用十分显著。因此，在成都东部地区植树造林不仅能改善环境气候，更能创造巨大的生态经济效益。

The Countermeasures of Climate Change and Ecological Status of Hilly Region in Eastern Chengdu

By utilizing characteristics of the temporal and spatial variation and by analyzing characteristics of the mutation of temperature and precipitation through using the temperature and precipitation data of the eastern part of Chengdu, the results can be concluded as follow： the temperature was increasing and precipitation was decreasing in recent 50 years in the eastern Chengdu. Through analyzing the correlation between TH and greening rate of 5 tenaperature zones in Chengdu, it shows that： with the greening rate increasing, both the avera4e temperature and the highest temperature are decreasing, and the humidity is increasing. Therefore, forestation in the eastern part of Chengdu will not only improve the environment of climate, but also create tremendous eoological and economic benefits.
