【摘要】：本论文调查研究的对象为广义上的乡土树种,以邯郸市建成区绿地为研究区域,在大量查阅相关文献的基础上,运用分层随机抽样调查法进行实地调查,并结合当地专家咨询等研究方法,研究分析了邯郸市园林绿地中乡土树种的应用情况;并运用综合评价体系对邯郸市园林中应用的乡土树种进行了评价分级,以获得乡土树种在当地园林绿地中的应用价值。本论文的主要研究成果如下:(1)邯郸市园林绿地中应用的乡土树种有41科84属130种,占所调查树种总数的62.2%,占调查总株数的65.6%。其中乡土乔木的数量最多,有71种;其次是乡土灌木,有51种,木质藤本最少,仅有8种。通过对调查数据的分析发现,乡土树种主要分布在蔷薇科,有10属26种,占所调查乡土树种总种数的20.0%,其次是豆科、木犀科、忍冬科等有限的少数科内。(2)对5种园林绿地类型的乡土树种的科属分布情况及数量进行调查的结果表明,不同的绿地类型,其乡土树种在种类、数量上的分布情况有所不同。公园绿地分布种类最多,有117种,其次是居住区绿地,交通绿地由于空间受到局限性种类最少。各种绿地类型中普遍存在乔木多于灌木的现象,这也说明在邯郸市园林绿地中,乡土乔木比乡土灌木应用更为广泛。(3)在园林绿地中应用频率较高的乡土树种有国槐、垂柳、悬铃木、紫薇、白皮松、月季、大叶黄杨、木槿、石榴、迎春等,这些有限的应用频率较高的乡土树种担任着邯郸市骨干树种的重要角色;其丰富度指数和多样性指数乔木灌木木质藤本,公园绿地居住区绿地滨河绿地,道路交通绿地最小;均匀度指数居住区绿地最大。(4)通过对乡土树种综合评价得知,综合评价指数较高的乔木有垂柳、香椿、白蜡、皂荚等,灌木有金银木、接骨木、文冠果等,木质藤本有野蔷薇、藤本月季、紫藤等。在综合评价的基础上,结合乡土树种在园林中实际应用频率分析结果,筛选出优良的但未得到广泛应用的乡土树种17种并进行推荐应用。(5)在调查分析的基础上,对邯郸市乡土树种的应用提出了扩大灌木类乡土树种应用,优化乡土树种结构;增加优良乡土树种的应用频率;合理开发并扩大应用优良的乡土树种资源;丰富乡土树种景观,凸显地方特色四个方面的建议。
[Abstract]:The research object of this paper is the local tree species in a broad sense. Taking the green space in the built area of Handan City as the research area, and on the basis of consulting a large number of related documents, the stratified random sampling method is used to carry out the field investigation. The application of native tree species in garden green space of Handan City was studied and analyzed by using local expert consultation and other research methods. In order to obtain the application value of native tree species in local garden green space, the local tree species used in Handan city garden were evaluated and classified by comprehensive evaluation system. The main results of this paper are as follows: (1) there are 130 native tree species belonging to 84 genera and 41 families, accounting for 62.2% of the total number of trees investigated and 65.6% of the total number of plants investigated. There were 71 species of native trees, 51 species of native shrubs and 8 species of woody vines. Through the analysis of the investigation data, it is found that the native tree species are mainly distributed in the Rosaceae, with 26 species belonging to 10 genera, accounting for 20.0% of the total number of native tree species investigated, followed by legumes and Oleaceae. (2) the investigation on the distribution and quantity of the families and genera of five local tree species of garden green space showed that the local tree species of different greenbelt types were native species. The distribution is different in quantity. The distribution of park greenbelt is the most, there are 117 species, followed by residential green space, traffic green space is the least due to space limitations. There are more trees than shrubs in all kinds of green space types, which also shows that local trees are more widely used than native shrubs in the garden green space of Handan. (3) the local tree species with higher application frequency in the garden green space are Sophora japonica. Weeping willow, hanging Suzuki, Lagerstroemia, White Pine, Rosa, Poplar, Althea, Pomegranate, Yingchun, these limited local tree species with high application frequency play an important role in Handan. The richness index and diversity index of Arbor and shrub woody vines, green land of park green district, riverfront green space and road traffic green space are the smallest. The evenness index of green space in residential area was the largest. (4) through the comprehensive evaluation of native tree species, it was found that the trees with higher comprehensive evaluation index included weeping willow, Chinese toon, white wax, acacia, and so on, and the shrubs had gold and silver trees, elderberry, asparagus fruit and so on. Woody vines have wild rose, vines rose, wisteria and so on. On the basis of comprehensive evaluation, combined with the practical application frequency analysis results of native tree species in gardens, 17 local tree species were selected and recommended. (5) on the basis of investigation and analysis, 17 local tree species were selected and applied. To the application of native tree species in Handan city, it is proposed to expand the application of shrub native tree species and optimize the structure of native tree species. To increase the application frequency of fine local tree species; to develop and expand the application of fine local tree species resources rationally; to enrich the landscape of local tree species; to highlight the local characteristics of the four aspects of the proposal.
