【摘要】：道路运行会对路域土壤和植被产生间接的破坏,采用样方法对国道213合作市郊段路域小型取土区进行调查研究。结果表明:人为干扰对路域生态环境造成了明显的破坏,路域人为取土区植被和土壤在自然状态下的整体修复情况一般。受地表径流影响,取土区中央土壤肥力自然修复较好,坡面土壤肥力自然修复较差。由于取土区中央特殊的生长环境,植被自然修复状况一般,植物种类与对照区明显不同;在土壤肥力和修复时间的双重作用下,坡面植被自然修复结果较差。因此,建议加强环保宣传,制定路域生态环境保护制度,及时对干扰区进行人工修复。
[Abstract]:The road operation will cause indirect damage to the soil and vegetation of the road area. The investigation and study on the small soil acquisition area of the road area in the suburb section of National Road 213 by using the sample method show that the man-made disturbance has caused obvious damage to the ecological environment of the road area. The total restoration of vegetation and soil in the natural state of the road area is normal. Affected by the surface runoff, the natural restoration of soil fertility in the center of the area is better. The natural restoration of soil fertility on slope is poor. Because of the special growing environment in the center of the sampling area, the natural restoration condition of vegetation is general, and the species of plant is obviously different from that of the control area, and under the dual action of soil fertility and remediation time, The results of natural restoration of slope vegetation are poor. Therefore, it is suggested to strengthen environmental protection publicity, formulate ecological environmental protection system in road area, and carry out artificial restoration of disturbed areas in time.
