| 摘要: |
| 为了防治外来入侵物种薇甘菊 Mikania micrantha 的过度繁殖，在惠州汤泉林场与惠城区试验地设置 16 个样方，在人工除草（包括全部薇甘菊）后搭配种植主栽乔木 3 种，套种 4 种类型乔木搭配，并设置固定样方调查薇甘菊的生物量、盖度、密度及其周围种植的、野生的乔灌草植物生长量、盖度。研究表明：（1）薇甘菊盖度与优势树种的总盖度呈负相关；（2）薇甘菊盖度与≥ 1.5 m 木本层植物的总盖度呈负相关；（3）薇甘菊盖度与 Simpson 物种多样性呈正相关，与 Simpson 物种均匀性指数呈负相关；（4）薇甘菊盖度与 Shannon-Wiener 多样性和均匀性指数均呈负相关。（5）薇甘菊盖度与其他植物总盖度呈显著正相关。试验表明，植物群落内通过种植乔木达到增加群落郁闭度的方式对薇甘菊的防治有效。 |

| Abstract: |
| 16 plots were put up in Huizhou Tangquan Forest Farm and Huicheng District to manage the invasive alien species Mikania micrantha excessive multiplication. Three primary trees were planted, four varieties of trees were interplanted, and fixed samples were placed after artificial weeding（containing all M. micrantha）. Fang researched the biomass, coverage, and density of M. micrantha and the development and covering of natural trees, shrubs and grasses placed around them. According to preliminary research,（1）M. micrantha coverage was negatively correlated with the total cover of dominant tree species;（2）M. micrantha coverage was negatively correlated with the total cover of plants in the woody layer of ≥ 1.5 m;（3）The coverage of M. micrantha was favorably connected with Simpson species diversity and negatively correlated with Simpson species uniformity index;（4）The coverage of M. micrantha was negatively correlated with both Shannon-Wiener diversity and uniformity indices;（5）The coverage of M. micrantha was significantly and positively correlated with the total cover of other plants. Experiment shows, it is effective to control M. micrantha by planting trees to increase the canopy density in the plant community. |
