合理的绿地植被建设和管理是提高城市蓄水能力和减少城市内涝的重要途径。该文以武汉市城区8种代表性绿地植被的表层土壤为研究对象,通过测定土壤理化性质和水力学特征参数,量化了不同类型绿地植被对表层土壤水分入渗和保持性能的影响,并揭示了土壤理化性质对其影响的机制。结果表明:不同植被类型表层土壤水分入渗性能和持水能力差异显著,天然香樟林、玉兰园、桂花园和牡丹园具有较好的入渗性能,表现为较高的饱和导水率(179.70 ~ 441.69 cm/d),其次是人工草坪(31.53 ~ 126.60 cm/d),而樱花园、梅花园和桃李园的入渗性能最差(22.40 ~ 57.99 cm/d) 。天然香樟林土壤持水能力最强,表现为最高的田间...

Reasonable green space vegetation construction and management is an effective way to increase urban water storage capacity and reduce urban waterlog. Eight urban green space locations characterized by different vegetation types in the Wuhan city were selected to collect the surface soil samples. The effects of green space vegetation types on water infiltration rate and water retention capacity of surface soils were quantified by measuring the soil physiochemical properties and hydraulic parameters. Furthermore, the relationships between the physiochemical properties and hydraulic parameters we...
