摘　　要：通过试验测定,分析了北方草坪草叶面积与其修剪特征之间的关系,进而建立草坪不同修剪高度下的叶面积指数关系模型。结果表明,草坪草叶面积指数随着草坪修剪高度的增加而增加,叶片宽度对叶面积指数变化的影响更大。在此基础上,以天津市某高尔夫球场为例,对该球场内不同组成部分的草坪绿量进行调查统计,并结合草地早熟禾单位面积日蒸腾量、释氧固碳量、蒸腾释水量和吸热量,计算得出案例中高尔夫球场草坪的生态效益为年蒸腾总量88119744.59mol,年吸收CO2量10771.66t,年释放O2量7830.67t,年蒸腾吸热量6903753.43GJ,并运用环境效益评价法估算出该球场草坪年吸收CO2量总价值为1102.59万元,年释放O2量总价值为313.23万元,年蒸腾吸热总价值为126760.58万元,总生态价值量达128176.95万元。Through tests and measurements,this paper analyzed the relationships between the leaf area and mowing characteristic of golf course turfs in North China,and further,established a relational model of turf leaf area index with different mowing height. There was a positive relationship between the leaf area index and the mowing height,and the blade width had greater effects on the leaf area index. Taking a golf course in Tianjin City as the case,a survey was made on the turf green quantity in its different components,and the ecological benefits of the golf course were calculated,based on the daily transpiration,O2 release and CO2 intake,and heat absorption per unit area Kentucky bluegrass. The annual transpiration of the golf course was 88119744.59 mol,annual O2 release and CO2 intake were 7830.67 t and 10771.66 t,respectively,and annual heat absorption for transpiration was 6903753.43 GJ. The economic benefits of the golf course estimated by environmental benefit evaluation method were 1102.59 ten thousand yuan for annual CO2 intake,313.23 ten thousand yuan for annual O2 discharge,and 126760.58 ten thousand yuan for annual heat absorption for transpiration,with the total ecological value being 128176.95 ten thousand yuan.
