山地城市公园坡地对林地植物景观的影响研究

Influence of Slope Land on Plant Landscape of Forest Land in Mountain City Park

为探讨坡地对林地植物景观的影响,提出针对山地城市林地植物景观营造的意见,对重庆市主城区五大森林公园进行基础调查,采用层次分析法(APH)对其进行景观评价。结果表明,调查样方内共有维管植物49科80属88种,随坡度的增加,物种数逐渐减少,整体栽培度降低;坡度为0～15°条件下最佳栽培度为76°～100°,坡度为16°～30°条件下最佳栽培度为51°～75°,坡度为31°～45°条件下最佳栽培度为26°～50°。提出针对不同的坡度段选择不同的栽培度,既能保持良好的生态特性,又能提高植物景观的观赏性。并针对不同坡度段给出适宜的植物配置模式和植物种类建议。

In order to discuss the influence of slope land on the plant landscape of forest land,this paper put forward the ideas on the construction of plant landscape in mountain urban forest land,conducted the survey on the five forest parks in the main urban area of Chongqing,and evaluated the landscape by the analytic hierarchy process(APH).The results showed that 88 species of vascular plants belonged to 80 genera and 49 families in the sample plot.The number of species and the overall cultivation degree decreased gradually with the increase of slope.Thebest cultivated slopes were 76°-100°for the 0°-15°slope,51°-75°for the 16°-30°slope,and 26°-50°for the 31°-45°slope.Different cultivation degrees for different slope sections maintained good ecological characteristics,but also improved the ornamental value of plant landscape.The plant configuration patterns and plant species should be suitable for different slope sections.
