| 为研究山区河道工程扰动边坡植物群落演替规律，以石葵河生态治理工程区为研究对象，采用典型样地抽样调查法，对河道边坡植被恢复情况进行连续3年的调查。〖JP〗结果显示，在生态修复期内共发现105种植物，隶属38科97属，以禾本科、豆科和菊科为主；随着时间推移，功能群物种组成有明显波动，豆科植物占比下降，禾本科、菊科植物占比升高；优势物种发生改变，从初期多年生草本占绝对优势逐步向乔灌草共存的趋势演替；植物群落生物多样性指数均呈上升趋势。针对研究区生态修复，试提出以当地优势物种胡枝子+大青+狗牙根+牛筋草+羽芒菊为主的灌草结合植物配置模式。 |

| In order to study the succession law of slope plant community disturbed by river engineering in mountainous area, taking Shikui River ecological treatment project area as the research object, the vegetation restoration of river slope was investigated for three consecutive years by using typical sample plot sampling method. The results showed that during the ecological recovery period, 105 species of plants were found belonging to 38 families and 97 genera, mainly Gramineae, Leguminosae and Compositae. The species composition of functional groups fluctuated significantly with time, the proportion of Legumes decreased and the proportion of Gramineae and Compositae increased. The dominant species changed from the absolute dominance of perennial herbs in the initial stage to the coexistence of trees, shrubs and grasses. The biodiversity index of the plant community showed an upward trend. For ecological restoration in the research area, it tried to propose a configuration model of shrub grass combination based on local dominant species Lespedeza bicolor Turcz.+Clerodendrum cyrtophyllum Turcz.+Cynodon dactylon（L.）Pers.+Eleusine indica(L.)Gaertn.+Tridax procumbens L. |
