摘　　要：农村道路及其配套设施建设对农业机械化、现代化有显著影响。该文论述了农村道路网络、农村道路设计及其生态景观效应。农村道路网络规划应与农业产业化紧密结合,在满足连通度的同时,尽可能有益于农村居民点的适度集中,减少对耕地斑块的分割和干扰;路面、路基等设计应综合考虑土壤、工程地质和地形地貌等条件,就地取材;对区域尺度景观的干扰,可通过数个村级尺度单元间"通道-阻隔"效应的耦合积聚而消减。农村道路,特别是丘陵区的农村道路建设,要围绕提高农业机械化水平、优化农村道路网和提高工程设计标准来进行,以改善道路生态景观。Rural roads and their facilities make a significant impact on the level of mechanization and modernization in agricultural production.This paper provides a comprehensive review on the rural roads involving the network,design and its effects on the ecological landscape.Planning and design of rural road should be closely integrated with the industrialization of agriculture.Beside the connectivity,its layout should lead to moderate concentration of rural settlements as well as reduce the separation and interference of farmland patches.The design of pavement and subgrade should be adapted to local conditions in terms of multiple those like soil,engineering geological and hydrogeological and built with local materials.There is a coupling and mutual feed from passing-obstructing effect among lots of village-scale cells,whose accumulation can build up the interference scenarios on the landscape under the large regional scale unit.So,aiming at improving the level of agricultural mechanization,the research on construction of rural roads,especially in hilly area,will be strengthened by the optimization of the network structure,raising standards of the engineering design and the improvement of the ecological landscape.
