- Abstract:
- In order to investigate the effect of different desert oasis Ecotone shelterbelt forest age on microclimate within the region, reveal the spatial and temporal variation of wind speed, temperature, humidity and other weather elements for Qiemo Oasis protection forest ecological barrier blocks the peripheral zone, we set up five observation points to monitor the wind speed, air temperature, humidity in a small automatic weather station on the shelterbelt area and exposed quicksand area. The results showed that: (1) compared with bare quicksand, the windproof efficacy of Haloxylon ammodendron forests (forest ages of 2-year, 5-year and 7-year) and 17-year mixed forest were 5.26%, 31.57%, 42.10%, 78.94%. Mixed (17-year) of the draft efficacy was significantly higher than Haloxylon ammodendron forests (ages of 2-year, 5-year and 7-year), but as the wind speed increases the effectiveness of wind has declined; (2) the shelterbelt can reduce the average daily temperature in the region, and the greater forest age is the more obvious cooling effect is, but after reaching a certain age, the cooling effect no longer enhanced; (3) night temperature of shelterbelt area is greater than that of the bare sand area, daytime temperature of mixed (17-year) zone is significantly higher than that of the bare sand area; (4) the shelterbelt can increase air humidity, the greater the forest age is, the stronger humidifying effect is, moist effect at night in protection forest area is higher than that in the daytime.
