通过对北京鸿华高尔夫球场内外的PM 2．5、PM 10、空气负离子、温湿度及噪音等生态效益因子连续14 d的实地监测，分析其日变化规律、不同立地条件下的差异及各因子间的相关性，结果表明：球场内各生态效益因子的含量均优于球场外，并且乔灌草复合绿地对各因子的净化效率均高于乔草型和草坪型绿地。温湿度日变化曲线分别呈现单峰和单谷状，日平均气温降低2．1℃，增加相对湿度9．2％。PM 2．5与PM 10的日变化规律呈现出双峰趋势，早晚较高，午后较低，球场对两者的日均净化率分别为25．9％和26．6％，并且两者间具有极显著的正相关性，其含量与温湿度分别呈极显著的正相关性和负相关性。球场内空气负离子早晚较高，午后较低，其含量是球场外的4．95倍，与温湿度分别呈现出极显著的负相关性和正相关性。球场内的噪声显著低于球场外，平均降噪率为11．8％，其日变化规律呈现出先上升，然后基本保持微小波动的趋势。
通過對北京鴻華高爾伕毬場內外的PM 2．5、PM 10、空氣負離子、溫濕度及譟音等生態效益因子連續14 d的實地鑑測，分析其日變化規律、不同立地條件下的差異及各因子間的相關性，結果錶明：毬場內各生態效益因子的含量均優于毬場外，併且喬灌草複閤綠地對各因子的淨化效率均高于喬草型和草坪型綠地。溫濕度日變化麯線分彆呈現單峰和單穀狀，日平均氣溫降低2．1℃，增加相對濕度9．2％。PM 2．5與PM 10的日變化規律呈現齣雙峰趨勢，早晚較高，午後較低，毬場對兩者的日均淨化率分彆為25．9％和26．6％，併且兩者間具有極顯著的正相關性，其含量與溫濕度分彆呈極顯著的正相關性和負相關性。毬場內空氣負離子早晚較高，午後較低，其含量是毬場外的4．95倍，與溫濕度分彆呈現齣極顯著的負相關性和正相關性。毬場內的譟聲顯著低于毬場外，平均降譟率為11．8％，其日變化規律呈現齣先上升，然後基本保持微小波動的趨勢。

The daily variation,difference of various site conditions and correlation of temperature,humidity, atmospheric particulate matter of 2.5μm diameter or less and 10μm diameter or less (PM 2.5,PM 10),nega-tive air ions and noise were monitored for 14 days,at sites both on and off the golf course.The level of every factor in the golf course was better than outside the golf course,and the purification efficiency of compound green space with arbor-shrub-grass was superior to arbor-grass and grass.Daily variation of temperature and relative humidity showed a single peak and trough pattern,respectively.Compared with the outside,the daily average temperature in the golf course was 2 .1℃ lower,the relative humidity increased by 9 .2%.The daily variation of PM 2.5 and PM 10 showed a bimodal trend,rising in the morning,falling to a minimum in after-noon,and then gradually increasing.The daily purification rates of them were 25.9% and 26.6%,respective-ly,on the golf course.These two measures had a highly significant correlation,and also had a highly signifi-cant positive correlation with temperature and negative correlation with humidity.The level of negative air ions in the golf course was 4.95 times higher than outside the golf course,which had a similar but opposite diurnal pattern and correlation with temperature and humidity to that of particulate matter.The noise in the golf course was significantly (1 1 .8%)lower than outside the golf course.
