【摘要】：道路運(yùn)行會(huì)對(duì)路域土壤和植被產(chǎn)生間接的破壞,采用樣方法對(duì)國(guó)道213合作市郊段路域小型取土區(qū)進(jìn)行調(diào)查研究。結(jié)果表明:人為干擾對(duì)路域生態(tài)環(huán)境造成了明顯的破壞,路域人為取土區(qū)植被和土壤在自然狀態(tài)下的整體修復(fù)情況一般。受地表徑流影響,取土區(qū)中央土壤肥力自然修復(fù)較好,坡面土壤肥力自然修復(fù)較差。由于取土區(qū)中央特殊的生長(zhǎng)環(huán)境,植被自然修復(fù)狀況一般,植物種類(lèi)與對(duì)照區(qū)明顯不同;在土壤肥力和修復(fù)時(shí)間的雙重作用下,坡面植被自然修復(fù)結(jié)果較差。因此,建議加強(qiáng)環(huán)保宣傳,制定路域生態(tài)環(huán)境保護(hù)制度,及時(shí)對(duì)干擾區(qū)進(jìn)行人工修復(fù)。
[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.
