摘要
以女儿寨小流域为研究对象,着重研究了植被恢复重建过程中小流域系统的小气候变化特征.随着小流域内的植被恢复与重建,小流域内最高气温约降低了1～4℃,尤其以夏、秋季更为突出,约降低了3～4℃;最低气温提高了1～2℃,夏季较其它季节更为显著一些;森林不能降低小流域的日平均气温,但能略微增加秋冬季的平均气温0.1～0.5℃;平均地面温度降低了0.9～1.3℃,秋冬季的地面平均温度略微增加0.1～0.5℃;年降水量增加了77～115 mm;年蒸发量降低105～175mm.小流域小气候环境发生了较大的变化,小气候质量在不断的提高.
Research was performed on the small watershed of the Daughter Stockaded Village, examining the changing characteristics of the microclimate during the vegetation and rebuilding period,the highest temperature was decrease 1 - 4℃ ,especial in the summer and autumn （ decrease 3 - 4℃ ）, the lowest temperature was increase 1 - 2℃, especial in the summer. The forest did not cause a decease in the daily average temperature in small watershed, but increased the average temperature 0.1 - 0.5℃ in the autumn and winter, decreasing the average temperature of the earth surface 0.9 - 1.3 ℃, and increasing the average temperature of the earth surface 0.1 - 0.5℃ in the autumn and winter. And increase the annual amount of precipitation 77 - 155 mm, and a decrease the annual depredation 105 - 175 mm was measured. The forest can change in the mieroelimate of the small watershed and increase the quality of the mieroelimate.
