【摘要】 论文对太湖流域上游区域安吉县城绿地系统的水生态服务功能进行了系统研究。在资料收集和实地调查的基础上,研究将安吉绿地分为居住区及单位附属绿地、公园绿地、道路绿地和防护绿地。研究表明安吉县城绿地系统具有明显的减少地表径流和净化水质的水生态功能。2008年,安吉县城绿地系统共减少地表径流400.3×104m3;削减雨水径流污染物COD16.0 t、TN7.91t、NH4-N0.22t和TP0.29t。绿地系统的水生态服务功能与绿地面积以及植被组成相关,在安吉县城绿地系统中,总截留降水和去除污染物最多的为居住区及单位附属绿地,其次为公园绿地、道路绿地和防护绿地。更多还原

【Abstract】 In this paper,we studied the water ecological function of green space in Anji County Seat of the upper Taihu Lake Basin.Basing on data collection and fieldwork,we divided green space into attached and residential quarter green area,park green area,street green area,and green area for environmental protection.These systems generate a range of water ecological services which can intercept precipitation,reduce surface runoff,and purify water.In the paper,the green space has intercepted precipitation 400.3×104 m3,and reduced COD 16.0 t,TN 7.91 t,NH4-N 0.22 t,and TP 0.29 t in Anji County Seat in 2008.The water ecological function is affected by green space area and vegetation type,therefore,the attached and residential quarter green area and the park green area have higher water ecological functions.更多还原
