摘  要：
[目的]为揭示黄土高原中心地带甘肃省陇东地区植被完全毁坏(或严重破坏)的代表区域庆城县和华池县的生态气候效应。[方法]利用庆城和华池县气象站观测资料与作为原生态气候本底标准的子午岭林区太白镇气象站同步观测气候资料,通过比较分析月平均气象要素差值的年变化曲线和资料序列的方差F统计检验。[结果]庆城县各月与华池站1、3～12月的平均气温明显高于子午岭林区;5～7、9～10月降水量、降水日数和空气湿度明显少(小)于林地;盛夏6～8月平均蒸发量明显大于林地。[结论]植被完全毁坏或严重破坏的黄土高原中部陇东地区具有明显的干暖化和水分利用率降低的生态气候效应特征。

摘  要：
[Objective]The research aimed to reveal the ecological climate effects of Qingcheng and Huachi Counties whose vegetation had been destroyed completely(or damaged severely),which located in the eastern regions of Gansu Province — the heartland of Loess Plateau.[Method]Using the observation data from Qingcheng and Huachi meteorological station and the synchronous climate observation data from Taibai meteorological station in Ziwuling forest zoon,which had been regarded as the original ecology climate standard,the yearly change curve of meteorological elements on the monthy average difference and the variance F test statistics of the sequence data were compared and analyzed.[Result]The average temperature of months in Qingcheng station and January and March to December in Huachi station was significantly higher than Ziwuling forest zoon.The precipitation,the number days of precipitation and humidity were significantly less(smaller)than the forest during May to July,September to October.The evaporation is significantly greater than forestland during June to August.[Conclusion]There had the characteristics of ecological climatic effect,namely,dry-warming and the reduction of water utilization ratio became more obvious in the eastern regions of Gansu Province — the heartland of Loess Plateau whose vegetation had been completely destroyed or seriously damaged.
