公路的建设和运营对周边地区土壤理化性质产生重要影响。由于不同研究区域地质构造、土壤母质、气候、微地形、植被类型和恢复时间等方面的差异，各研究地点土壤理化性质和营养元素的变化规律存在差异。根据不同研究区域的实际，本文提出了公路周边区域相应的土壤改良措施，以保证公路沿线生态防护的持久性及可持续性。

The construction and operation of highway has important effects on the physical and chemical property of soil along the high -way.The changing laws of the physical and chemical property of soil along the highway are different because of the difference of geolog -ical structure, rock, climate, microlandform, type of vegetation and restoration time et al .in different study zones.Based on the actual situation of different study zones , this paper put forward improvement measures of soil along the highway in order to ensure the sustain -ability of ecological safety along the highway .
