摘要
为进一步了解长春市城市绿地土壤质量状况,揭示绿地土壤存在的主要问题,以高新北区为例,按照绿地划分方法,根据其地理位置和利用类型,对高新北区公园绿地和交通绿地土壤质量进行了分析.结果表明:公园绿地和交通绿地土壤容重均偏高,多数土壤有碱化趋势,土壤有机质和水解氮含量处于偏低水平,土壤速效磷含量处于中等偏低水平,土壤速效钾含量处于中等水平.土壤有机质对水解氮、速效磷的含量影响较大,对速效钾的影响较小.在管理上,应加强绿地植被土壤养分供给量.
In order to further understand the soil quality of Changch main existing problems on the bass of its geographical location and distribution and growth of the vegetation of the park, divided un urban green space,and reveal its the available type. According to the it into ＂park green space＂ and ＂transportation green space＂ to analyze the soil quality of Gaoxin North District. The results show the soil bulk density is on the high side in the park green space and traffic green space,nost of the soil is alkaline trend,hydrolysis of soil organic matter and nitrogen content at a low level, soil available P content in the medium to low level, soil available potassium content in the medium level. The content of soil organic matter on hydrolysis N,available P,less effect on the available K. So should strengthen sufficient soil nutrient for the green vegetation in the management.
