我国西南地区多属国家滇黔桂石漠化集中连片特困地区,受地域影响交通基础设施严重落后,为使其尽快脱贫致富,解决农民出行问题,迫切需要农村公路建设的推进。但是,目前依然面临着结构层次不合理、县乡道改造压力增加、联络道路建设不足、网络化程度低等问题。 Most of Southwest China is a concentrated contiguous destitute area of ​​national Yunnan, Guizhou and Guangxi rocky desertification. Due to the serious influence of the terrain, the transport infrastructure lags behind. In order to eliminate poverty and solve the peasants’ travel problems as soon as possible, it is urgent to promote the rural road construction. However, at present, we still face problems such as irrational structural levels, increasing pressure on the reconstruction of county and township roads, inadequate construction of contact roads, and low degree of networkization.
