高速公路绿化设计及植物选择

Afforestation Design and Plant Selection for Freeway Construction

阐述了高速公路绿化设计的功能及原则,分析了目前高速公路绿化所存在的问题.鉴于植物的选择直接影响着绿化效果及其功能的实现,是绿化设计中亟须完善的首要环节.因此探讨了高速公路重点绿化区域的物种选择原则.并依据该原则,以某高速公路为例,在对原生植被进行调查和土壤采样分析其pH值、有机质、阳离子交换量等参数的基础上,根据该高速公路的立地条件,结合不同绿化部位的功能需求,筛选出适宜的绿化物种,提出一种推荐方案.

This article illustrates the function and principle of afforestation design on the freeway, and analyzes current problems in the afforestation project. Because plant selection affects the quality of afforestation and the realization of goal directly, it is the first aspects to be perfected. Therefore, this paper discusses the methods to choose plants scientifically in main afforestation areas along the freeway. Taking an freeway for an example, according to the above principles, on the basis of the investigation of the original vegetation and the measuring results of soil parameters, such as PH value, organic matter, cation exchanger and so on, considering the condition and function demand of different afforestation areas, this article selects suitable afforestation plants and puts forward constructive advice.
