为摸清中巴喀喇昆仑公路（简称中巴公路）30年运营对两侧植被的影响范围与程度、公路干扰区域（取弃土场、施工便道等）处植被自然恢复能力，采用样线法和样方法于2009年9月20日～28日、2010年9月8日～15日和2011年9月22日～27日对中巴公路雷克特桥至红其拉甫段（即 K470＋500～K811＋343段）两侧200 m 范围内的各种植被类型及工程占地干扰区域进行了调查和实测。结果显示：公路两侧0～1 m 范围内（即土质边沟处）的物种丰富度、盖度均显著高于99～100 m（自然背景）处，且生物量、多样性指数、优势度指数和均匀度指数均有高于其他距离的趋势；公路路侧干扰样方在外貌、结构组成上已与天然背景样方的植物群落无明显的不同，但植物群落盖度、种类组成、植株高度，随着植被类型的不同与天然群落稍有差别。本研究为正在建设中的中巴公路改扩建工程的生态排水沟建设、植被恢复技术策略（以自然恢复为主、人工恢复为辅）的制定提供了理论依据。

Line transect method and plot sampling method are applied to various vegetation on both roadsides up to 200m range from 20th to 28th September,2009,8th to 15 th September,2010 and 22th to 27 th September,2011 to understand the road effect zone,extent and natural recovery ability of vegetation in artificial affected area (road construction and disturb area), which is caused by 30 years operation of Karakoram highway(KKH).The result shows that species richness and coverage on 0 ~1 range of both roadsides are much higher than the range of 99 ~100 m (natural background),while biomass,diversity index,dominance index and evenness index have the trend that higher than other ranges.The roadsides impact plots have no difference with natural background plots in terms of appearance and structural composition.However,plant community cover-age,species types and height of vegetation still have difference with natural community.This research provides theory basis for KKH ecological reconstruction and improvement project,in terms of ecological drainage construction and vegetation resto-ration technology strategy (guideline of natural recovery as main and artificial recovery as auxiliary).
