- Abstract:
-
Caragana microphylla is one of the key species for vegetation restoration in Horqin Sandy Land. Adopting field investigation and field experiments, the microclimate effects of artificial C. microphylla communities with different age were studied by observing wind velocity, air temperature, relative humidity and soil temperature. The results show that vegetation cover has an obvious wind-breaking effect near ground surface, the wind velocity in the 6- and 11-year-old C. microphylla shrubs at the height of 30 cm decreases by 71.9% and 76.0%, respectively, compared with shifting dunes, mean daily temperature in the 6- and 11-year-old C. microphylla communities is 3.7 ℃ and 4.9 ℃ which is lower than in shifting dunes, respectively; air relative humidity in the shrubs is higher than in shifting dunes; soil temperature in the plantation is lower than in shifting dunes. The observed results are of significance to further exploring material and energy exchange near surface layer of vegetation in the extremely arid conditions.
