摘要
土壤对雨水的渗透有重要的影响,调查分析绿地土壤的质地类别有助于初步评估土壤的雨水渗透性能。以位于豫北地区的新乡市为研究区,对34处土壤样点按照0～20cm、20～40cm、40～60cm和60～80cm4层进行了采样,共获取136组数据。结果表明:新乡市绿地的土壤类别中壤土的比例最高,质地以粉砂质壤土为主;土壤样点的垂直结构复杂,因此雨水渗透过程也十分复杂。海绵绿地建设中应充分考虑城市绿地土壤质地和类别的差异性,进行合理的改良以满足雨水渗透的要求。
The soil plays an important role of rainwater infiltration,and investigation and analysis about the texture and type of soil helps to preliminarily evaluate water infiltration.This study selects Xinxiang City in the north area of Henan Province as the study area.A total of 136 sets of data are obtained from 34 soil samples at the four layers of 0-20cm,20-40cm,40-60cm and 60-80cm.The results show that loam occupies the highest proportion in Xinxiang City,and the mainly texture is silty loam.The vertical structure of the soil sample is complex,which also makes the infiltration process of rainwater very complex.In the construction of urban green space,the differences of soil should be fully considered,and reasonable soil improvement should be made to meet the demand of rainwater optimization design.
