| 摘 要： | 应用植物生长率分析、盖度—时间动态分析的方法对公路边坡试验点植被群落数量特征进行了研究,并且通过对植被生长率、盖度、地径随时间的动态变化得出植物生长变化情况。同时为了分析植被生长形成的景观效果,应用层次分析法对试验点边坡植被恢复景观效应进行了定量评价,醒目程度在景观敏感性指标中最为重要;坡度、土壤侵蚀性和植被的恢复能力在景观视觉吸收能力指标中比较重要;植被覆盖率、自然性和空间配置在景观质量指标中比较重要。

| Abstract: | This paper used plant growth rate and coverage-time dynamic analysis to study the quantitative characteristics of vegetation community for expressway slope test spot,and it concluded the changes in plant growth through the growth rate,the coverage of the vegetation and the dynamic changing with time.In order to analyze the landscape effect of vegetation growth,it also quantitatively evaluated the landscape effect of vegetation restoration for expressway slope test point by analytic hierarchy process. |
