摘要

2004年8月

对甘肃省河西走廊中部铺设生态垫与不铺设生态垫的沙丘不同层次(0 cm

5 cm

10 cm

15 cm

20 cm)土壤温度进行观测和分析。结果表明

铺设生态垫后土壤温度的日平均值及各层平均值均比未铺设生态垫的流动沙丘低

铺垫后的沙丘各层日平均温度比流动沙丘分别降低5.5℃

4.0℃

2.4℃

2.1℃

1.6℃。铺设生态垫后土壤不同层次的温差均低于对照地流动沙丘

各层温差分别减小8.8℃

5.0℃

4.5℃

2.8℃

随着土层的加深

温差变化幅度也逐渐减小。研究初步认为

铺设生态垫能够显著降低沙丘表层15 cm以内的土壤温度

显著减缓15 cm以内的土壤温度日变幅。

Abstract

The temperature of sand dunes with eco-mat and without eco-mat in Hexi Corridor of Gansu Province was measured continuously in August，2004. The results showed that，eco-matting can effectively reduced the mean diurnal soil temperature and mean temperature of each layer (0，5，10，15，20 cm )，the mean daily soil temperature decreased about 5. 5℃，4. 0℃，2. 4℃，2. 1℃and 1. 6℃respectively if coveyed by eco-mat. The eco-matting also reduced the temperature difference of each layers

compared with the contrast of mobile dunes

the temperature difference after eco-matting were 8. 8℃，5. 0℃，4. 5℃，2. 8℃ and 2. 8℃from 0 cm to 20 cm respectively. Additionally

variance of soil temperature of each layers also tend to decreased as the soil depth going down. We can roughly concluded that eco-mat can effectively reduced soil temperature of the soil layer from 0 cm to 15 cm

and effectively slowed down the variance of soil temperature

both of which may benefit to reduce soil evaporation under high temperature.
