摘要
为系统评价曹妃甸绿化植物资源现状,通过实地调查和文献查阅法对曹妃甸主城区13条街道绿地和森林公园的植物资源进行了调查,并对曹妃甸城区13条街道绿地的土壤pH值和含盐量进行了测定。结果表明:曹妃甸主城区道路绿地和公园共有植物117种,隶属45科83属。其中,乔木类植物55种,隶属23科38属,占植物总数的47%;灌木层植物36种,隶属16科26属,占植物总数的31%;草本植物26种,隶属12科23属,占植物总数的22%。植物资源配置基本满足了道路绿化的功能性。主要街道绿地土壤pH值为7.21~8.34,呈碱性,土壤含盐量为0.041%~0.232%,大部分植物能正常生长。
In order to systematically evaluate the general situation of greening plants resources in Caofeidian, the street green land and forest parks in the main urban area of Caofeidian were investigated through field investigation and literature review,and the soil pH value and salt content were determined. The results showed that there are117 species of plants belonging to 45 families and 83 genera, among which 55 species of trees belong to 23 families and 38 genera,accounting for 47% of the total. There are 36 species of shrub layer, belonging to 16 families and 26 genera,accounting for 31% of the total. There are 26 kinds of herbaceous plants,belonging to 12 families and 23 genera,accounting for 22% of the total. The allocation of plant resources can basically meet the function of road greening. The soil pH value is 7.21-8.34,the salt content is 0.041%-0.232%,and most plants can grow normally.
