(6)保津高速公路河北段服务区绿化主要以庭院绿化形式为主,绿化植物以观花乔灌木及草坪为主,绿化植物种类较为丰富,服务区绿地类型以草坪、观花乔灌木
+草坪、灌木及草本护坡植被为主,绿化较好,存在的问题主要表现在乡土植物缺乏、绿量不足、人性化欠缺、停车场绿化效果较差四个方面。保津高速公路河北段互通区绿化整体上效果较好,植物种类丰富、群落层次结构多样,特色较为突出,景观效果良好。互通区绿化不足之处主要表现在个别互通区绿化不足,树种单调,植被覆盖率低,景观效果较差;部分互通区绿化养护粗放,导致乔灌木死亡、绿化植物或绿化图案被杂草淹没现象。
(7)针对保津高速公路河北段绿化现状及存在问题,提出了保津高速公路河北段绿化提升改造的对策措施,主要包括优化植物绿化种植模式、改善高速公路绿化植物生长的土壤环境、加强对绿化植物的养护、加强边坡底部平台及隔离栅外侧绿化四个方面。

Based on field survey,the paper summarizes the characteristics ofthe central isolation belt,slope and bottom platform,service area and the area of green plant species,plant configuration model,soil survey and environmental characteristics analysis ofHebei
main conclusions ofthis paper are嬲follows:
(1)Investigation and statistical results OH the plant position ofthe central isolation belt in Baojin Highway ofHebei section show that a total of wild and cultivated plants of 1 4 families,1 8 genera and 1 9 species in the belt,which Gramineae and Rosaceae
species respectively up to 4 and 3 species,other plants belong to the single family and
