中文摘要	为了探讨沙漠绿洲过渡带不同林龄的防护林对区域内小气候的影响,揭示风速、温度、湿度等气象要素的时空变化规律,针对且末绿洲边缘区块状防护林生态屏障,设置了5个观测点,采用小型自动气象站对防护林区和裸露流沙区的风速、空气温度、湿度进行连续同步观测。结果表明:(1)相对裸露流沙地,梭梭林(2a,5a,7a林龄),17a林龄混交林防风效能分别为5.26%,31.57%,42.10%,78.94%。混交林(17a)的防风效能显著高于梭梭林(2a,5a,7a林龄),但各防护林防风效能随着风速的增大有所下降。(2)防护林可以降低区域内的日均气温,且林龄越大,降温效果越明显;但达到一定年限后,降温效应不再增强。(3)夜晚裸露流沙区气温高于防护林区,白天混交林(17a)区气温显著高于裸露流沙区。(4)防护林可以增加空气湿度,林龄越大,增湿效应越强,防护林区夜晚的增湿效应高于白天。
英文摘要	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.
