摘要
以往的道路绿化带偏重景观效益或者防风害作用,却忽略了林带对农田的不利影响。通过对北京农区道路绿化带荫蔽影响规律的研究,导出了北京平原农区道路绿化带的最小宽度的计算公式,并应在此基础上提出了4种改良的绿化模式,对解决平原农区道路建设与农业生产之间的矛盾具有现实意义。
The conventional road greenbelt pattern focused on landscape benefits and the roles against damage functions and actually neglected the shade stress to farmland.By the study of the shade stress to the plain farmland area in Beijing City,a formula for calculating the minimum road greenbelt width is found.Four improved greenbelt patterns are proposed,which are of practical significance to solve contradictions between road construction and agricultural production.
