高等级公路水土保持绿化工程方案探讨

以天水一谗口高等级公路工程为例,系统地介绍了可行性研究阶段水土保持方案中绿化工程设计的要求及内容。首先根据项目主体的要求,确定不同绿化功能和要求的地块的分布和面积,并划分不同的防治分区;其次分析和评价各类绿化地的立地条件,合理划分立地因子,提出不同防治分区各绿化地块拟采用的植物种及布局方案;最后,根据项目立体建设的要求,研究项目对绿化的特殊要求,提出可行的绿化方案,并进行典型设计。

Replantation Project Plan of Soil and Water Conservation Along Highway

Taking the highway project from Tianshi to Chankou section as an example, the requirement and content of replantation project design of soil and water conservation plan at the fessibility research stage are intrduced systematically. (1) According to the requirement of the main project, the distribution and area of plots with different replantation function and requirement are determined, and different management plots need to be delimi-tied; (2) The stand condition of different replanted plot, the factors of different stands need to be rationally classified , therefore, the plant spices to be applied and distribution plan for different replantation plots of different management areas are proposed; (3) The specific requirement of the project in accordance with the general project is studied, and the replanting plan with higher feasibility is put forward, then the typical design is conducted.
