宣化漏斗葡萄架对庭院小气候的影响

Influence of Infundibular Grapes Frame on Garden Microclimate in Xuanhua

采用手持气象站对具有漏斗葡萄架庭院的温度、热指数、光照强度、相对湿度等指标进行了测定,以了解漏斗葡萄架对庭院小气候的影响。结果表明:从上午8:30到下午17:10时间段内,有漏斗葡萄架的庭院的气温、热指数明显低于没有漏斗葡萄的庭院,而且气温越高,差异越明显,二者的温度之差可以达到2.5℃;光照强度也有同样的变化趋势,二者的变化范围为4.19×104～11.16×104lx和1.38×104～3.33×104lx;而有漏斗葡萄架的庭院的相对湿度则明显高于没有漏斗葡萄架的庭院,二者最大差距可以达到7%左右。试验表明,漏斗葡萄架对庭院小气候有明显影响,在炎热的夏季,在有漏斗葡萄架的庭院中,光照、气温和体感温度更低,而湿度更大,人体感觉更为舒适。

Some indexes of yard with infundibular grapes frame such as temperature,heat index,illumination intensity and relative humidity by using the pocket weather tracker were measured,in order to understand the influence of infundibular grapes frame to garden microclimate. The results showed that in the period of time that from 8：30 a. In. to 17.10 p. m. , the temperature and heat index of yard with infundibular grapes frame were significantly less than them of yard without infundibular grapes frame, and the higher the temperature, the greater the differences, which could reach 2. 5℃; illumination intensity had the similar tendencies of change, which rangeed from 4. 19× 10^4 lx to 11.16× 10^4 lx and 1.38 × 10^4 lx to 3. 33× 10^4 lx;and the relative humidity of yard with infundibular grapes frame was obviously higher than that without frame,the biggest gap of them can reach about 7%. The data above showed that infundibular grapes frame had obvious influence on yard microclimate,it was both lower in illumination,temperature and felt air temperature and greater in humidity of yard with infundihular grapes frame in hot summer, which made the human body feels more comfortable.
