摘　　要：利用唐山站2008—2013年5—10月的草面温度(以下简称草温)和气温观测资料,分析草温的变化特征,并对比分析晴天、多云、阴天3种天空状况下2个温度要素的变化规律,借此提出相应的园区管理建议。研究发现:唐山市5—10月月平均草温7月达最高值,仲夏时节草温变化较平缓;平均状况下,一日中13:00草温最高,5:00草温最低;3种天空状况下,草温大于气温开始时间一致;气温大于草温开始时间阴天状况略晚于晴天和多云状况;草温的日较差大于气温的日较差;2个温度要素的最低值均出现在5:00;草温峰值出现在13:00,气温的峰值在晴天状况下出现在14:00—15:00,多云状况下出现在15:00,阴天状况下草温和气温变化较平缓,峰值出现在13:00—14:00;3种天空状况下,变温最大值出现时间有所不同。根据分析结果 ,建议园区植物灌溉应选择6:00—7:00和(或)16:00—17:00,最需进行叶面降温时间为12:00—13:00,夏季应增加喷水次数。Based on the observation data of grass temperature and air temperature in Tangshan City from May to October in 2008--2013 ,the change characteristics of grass temperature were analyzed, change regulation of grass temperature and air temperature in different sky conditions, such as sunny day, cloudy day and overcast were also analyzed, to put forward the corresponding park management suggestions.The results showed that the highest of the average grass temperature appeared in July,the grass temperature changed slowly.The highest temperature appeared at 13：00 and the lowest appears at 5 ： 00.Under different sky conditions, the time when grass temperature starting to catch up with air temperature was the same,but the time when air temperature starting to catch up with grass temperature was later in overcast, and the diurnal change of grass temperature was bigger.Both of the lowest temperature of grass and air appeared at 5 ：00,the highest temperature of grass appeared at 13 ： 00, the highest air temperature appeared at 14：00--15：00 in sunny day ,but at 15：00 in the cloudy day,in overcast, grass temperature and air temperature changed slowly.The max change value of temperature appeared at different times in different sky conditions.As a result, gardens are suggested to water at 6 ： 00--7 ： 00 or 16-- 17, and cool the
