摘要
本文以包头市东河区内的市区、农村、飞机场、南海子湿地、人工苗圃五个区域内的公园、行道树、游园、住宅小区、农田、湿地、绿化带和防护带等景观类型为调查对象,采用典型抽样法选取了32个有代表性的样带进行调查,并结合城市生态学和景观生态学原理,利用均匀度指数、丰富度指数、多样性指数、重要值、自然度等指标对东河区城市绿化现状做出具体规划和评价.结果表明:包头市城市绿化采用的树种较单一;城市绿地盖度较小且分布不均;群落结构较简单;对乡土树种开发较少;管护落后.因此,在今后城市绿化过程中,应充分考虑绿化在城市空间中的多样性,以及与包头市干旱气候的协调性和合理性,使东河区绿化景观向着物种多样性、自然性和空间结构多样性等方向发展.
32 representative sample areas,including parks,streets,blocks,fields,marshes and shelter belts are chosen from city,airport,village,natural reserves and artificial nursery of Donghe distinct in Baotou by using typical sampled method as investigation objects. Then species number,species richness,diversity index and important value together with the principles of urban ecology and landscape ecology were used to propose idiographic evaluations and plans. Conclusions are proposed finally： the species of arbor and shrub adopted by the urban green space of Donghe distinct are too humdrum; the coverage of urban green space is too small and the distributions are too unbalanced; The structure of the communities is too simple; the exploiture percentage of native plants is too small; The management falls short of the goal. Accordingly,the diversity of city space and in correspond with the arid climate of Baotou must be fully considered,to the effect that the virescence of Donghe distinct can be more diversified in plant species and space structure and become more natural.
