摘　　要：对陕北黄土丘陵沟壑区石油集输管线沿线9个区域的植被生长状况进行了调查。结果表明:沿线物种共计27科63属77种,其中菊科、禾本科、豆科、蔷薇科植物较多,分别占总物种数的23.38%、14.29%、12.99%和10.39%。各生活型植物的种类数表现为多年生草本>一二年生草本>灌木>乔木>半灌木>小乔木。各区域植被的Simpson多样性指数和Shannon-Wiener多样性指数具有相同的变化趋势,均与丰富度指数呈正相关,与优势度呈负相关。草本的丰富度、均匀度均高于乔灌木的。陕北黄土丘陵沟壑区石油管线沿线植被自然恢复潜力良好,采取的工程措施有利于该区植被恢复。石油集输管线的铺设尚未对陕北黄土丘陵区的植被产生破坏。The growth statuses of vegetations in 9 districts along petroleum gathering pipeline in loess hilly and gully region of northern Shaanxi were investigated. The investigated vegetation along the petroleum gathering pipeline belonged to 77 species, 63 genera and 27 families; among them, the species number in Compositae, Gramineae, Leguminosae and Rosaceae were the most, accounting for 23.38%, 14.29%, 12.99% and 10.3% of the total species number, respectively. The vegetation could be divided into 6 life forms, and the species number of various life-form plants revealed the following sequence： perennial herbs 〉 annum and biennial herbs 〉 shrubs 〉 arbors 〉 subshrubs 〉 small arbors. The Simpson diversity index and Shannon-Wiener diversity index of vegetations in different districts had the same variation tendency, and they were positively correlated with species richness index, while were negatively related to Simpson dominance index. The species richness index and evenness index of herbaceous plants were higher than those of arbors and shrubs. The vegetations along petroleum gathering pipeline in loess hilly and gully region of northern Shaanxi had a good natural recovery potential, and the adopted engineering measures were favorable for the vegetation restoration in this region. The laying of the petroleum gathering pipeline has not yet caused a serious damage to the vegetations in loess hilly and gully region of northern Shaanxi.
