【摘要】：現(xiàn)有國道G214線為二級(jí)公路，承擔(dān)著西寧至結(jié)古段玉樹災(zāi)后重建運(yùn)輸物資的主要任務(wù)，是物資運(yùn)輸?shù)闹饕ǖ�。沿線屬于高寒地帶，所處的地形地貌比較特殊，生態(tài)環(huán)境穩(wěn)定性較差，線路工程的建設(shè)引發(fā)了周邊生態(tài)環(huán)境的退化，如植被退化等生態(tài)問題。為實(shí)現(xiàn)經(jīng)濟(jì)與生態(tài)和諧發(fā)展的目標(biāo)，本課題通過對(duì)G214國道沿線的氣候環(huán)境，土壤特性，以及植被特點(diǎn)進(jìn)行調(diào)查，，對(duì)國道沿線植被恢復(fù)及保護(hù)措施展開研究。 該課題首先對(duì)G214國道進(jìn)行分段調(diào)查，了解沿線每一段區(qū)域自然植物群落，分析得出該段優(yōu)勢種群，并結(jié)合現(xiàn)有的研究技術(shù)，總結(jié)了沿線植被的生態(tài)適應(yīng)性，得出了植物種植最優(yōu)配比。通過對(duì)該地區(qū)其他已建公路建設(shè)工程植被恢復(fù)調(diào)查，初步了解植被恢復(fù)的效果，并分析總結(jié)存在問題。 研究過程中，篩選出公路沿線各區(qū)域段適宜的坡面植被恢復(fù)物種種類及配比。綜合道路沿線的地理和自然植被群落特征，利用小范圍的種植試驗(yàn)分析出合理的植物配比并提出邊坡綜合植被恢復(fù)的方法。
[Abstract]:The existing national highway G214 is a second-class highway, which is responsible for the main task of rebuilding and transporting materials after the disaster in Yushu from Xining to Jiegu, and is the main passage for material transportation. The stability of ecological environment is poor, and the construction of line project has caused the degradation of the surrounding ecological environment, such as vegetation degradation. In order to realize the goal of harmonious development of economy and ecology, this project is based on the climatic environment along the G214 national highway. Soil characteristics and vegetation characteristics were investigated and vegetation restoration and protection measures along the national highway were studied. This subject first carries on the subsection investigation to the G214 national highway, understands the natural plant community of each section along the route, analyzes and obtains the dominant population of this section, and combined with the existing research technology, summarizes the ecological adaptability of the vegetation along the line. Through the investigation of vegetation restoration in other highway construction projects in this area, the effect of vegetation restoration is preliminarily understood, and the existing problems are analyzed and summarized. In the course of the study, the suitable species types and ratios of slope vegetation restoration were selected for each region along the highway, and the geographical and natural vegetation community characteristics along the road were synthesised. The reasonable proportion of plants was analyzed by small scale planting experiment and the method of comprehensive vegetation restoration on slope was put forward.
