- Abstract
Caragana microphylla is one of the key species for vegetation restoration in Horqin Sandy Land. Adopting field investigation ad outdoor experiments, the mieroelimate effect of artificial C. microphylla communities with different restoration years were studied by observing wind velocity, air temperature, relative humidity and soil temperature. The results shotv that: (1) Caragana microphylla community ha an obvious wind-breaking effect near ground surface. Compaed with sbiting duues, the wind velocity in the 6-year-old and 11-year-old C. mierophylla shrubs at the height of 30 cm separately decreases by 71. 9% and 76. 0% . (2) Mean daily temperature in the 6-year-old and 11-year- old C. microphylla communities is 3. 7 °C and 4. 9 °C lower than in shifting dunes, respectively. (3) The relative humidity of air in the Caragarn microphylla shrubs is higher tha in shifting dunes. (4) Soil temperature in C. microphylla plantation is lotver than in shifting dunes. These results are signiieant in further exploring material and energy exchange near surface layer of atifieial vegetation in the extremely arid condition.
