摘　　要：为解决纳六晴高速穿越珙桐自然保护区时,路线对保护区内野生动植物生活环境产生影响的问题,研究了降低设计标高,增长保护区内隧道段落长度的路线方案1及完全绕避珙桐保护区的路线方案2,并从与野生动植物的关系、路线走向顺直程度、工程投资、地方政府诉求等方面,结合地质情况,对2个路线方案进行深入比选,结果表明穿越珙桐保护区的路线方案1更合理可行。In order to solve the problem of the impact of the route on the living environment of wild animals and plants in the Davidia involucrata nature reserve when Nayong-Liuzhi-Qinglong Expressway crosses the nature reserve.The route scheme I of reducing the design elevation and increasing the length of the tunnel section in the nature reserve and the route scheme II of completely bypassing the Davidia involucrata nature reserve are studied.From the relationship with wild animals and plants,route smoothness,project investment,local government demands,the two route schemes are deeply compared and selected in combination with geological conditions.The results show that the route scheme 1 passing through Davidia involucrata reserve is more reasonable and feasible.
