水—麻高速公路沿线生态系统中植物边坡生态位研究

The Study on Niche of Eight Herbaceous Plants in the Ecosystem along the Shui-Ma Highway

本文采用生态位理论对水—麻高速公路沿线8种革本植物进行了研究,结果表明:生态位宽度值越大的植物,它们之间的生态位重叠值也越大。合理的选取草本植物的种类和数目,从而不断的优化种群的生态位,构建一个具有多样化种群的稳定而高效的人工生态系统,使得高速公路沿线边坡生态系统尽快恢复。

The thesis studies eight herbaceous plant along the Shui-Ma highway through employing niche theory and presents the result that the bigger the niche breadth between plants,the larger the niche overlap index.In this thesis,the authors select reasonably the kind and number of herbaceous plants to optimize gradually the niche of species and establish an artificial ecosystem which boasts diversified species,stability and efficiency for the restoration of slope ecosystem along the highway as soon as possible.
