【摘要】：园林观赏类植物资源野外调查,是园林植物研究与利用的重要手段,不仅能丰富园林植物物种的多样性,同时也是保护野生观赏植物资源的重要方式。本文以巴林左旗、巴林右旗、克什克腾旗、阿鲁科尔沁旗、翁牛特旗五个区域的草地为研究对象,对完善草地现有植被资料,促进草地植被恢复,合理开发利用和保护该区域内的牧草种质、发展草地畜牧业也具有重要意义。研究结果如下:(1)通过踏查和样方调查,共发现地被植物有56科,210属,331种。其中以菊科(Compositae)、禾本科(Gramineae)、豆科(Leguminosae)植物为主;(2)通过样方调查,.巴林右旗草地植物的优势种为羊草(Leymuschinensis)和阴地蒿(Artemisiaylvatica),相对重要值分别为0.0928、0.0926,丛生隐子草(Cleistogenes caespitosa)、芦苇(Phragmites australis)和寸草(Carex duriuscula)等为伴生种,其相对重要值分别为0.0763、0.0751、0.0732;巴林左旗优势种为寸草,相对重要值为0.0796,伴生种为羊草、无芒隐子草(Cleistogenes songorica)和野亚麻(Linumstelleroides等,相对重要值分别为0.0723、0.0670、0.0656;克什克腾旗以寸草为优势种,相对重要值为0,1176,羊草、冰草(Agropyron cristatum)和小菅草(Themede minor)等为伴生种,其相对重要值分别为0.1128、0.0769、0.0660;阿鲁科尔沁旗草地植物的优势种为羊草,相对重要值为0.1059,寸草、糙隐子草(Cleistogenes squarrosa)、翻白委陵菜(Potentilla discolor)等为伴生种,相对重要值为0.0670、0.0641、0.0517;翁牛特旗草地植物的优势种为寸草;相对重要值为0.1244;芦苇、稗(Echinochloa crusgaalli)、车前(Plantago asiatica)等为伴生种,相对重要值为0.0643、0.0628、0.0466。(3)草地植物群落多样性存在极显著差异(P0.01),草地植物群落多样性指数随海拔的升高呈现先升高后降低的趋势,中等海拔处(800m)植物群落多样性最高。(4)利用AHP层次分析法对261种野生地被植物进行评价,结果表明,18种具有极高的开发利用价值,135种次之,57种开发利用价值一般,51种开发利用价值差;根据野生地被植物在园林中的应用方式,予以分类。(5)整理调查结果发现37种濒危植物,就其提出对野生观赏植物资源的保护以及可持续利用发展对策。
[Abstract]:The field investigation of landscape ornamental plant resources is an important means for the research and utilization of garden plants. It not only enriches the diversity of garden plants, but also is an important way to protect the resources of wild ornamental plants. The grassland in the five regions of Balin right Banner, Keshiketeng Banner, Arukorqin Banner and Weng Niute Banner are the research objects. To improve the existing vegetation data of grassland, to promote the restoration of grassland vegetation, to develop and utilize and protect the forage germplasm in this area rationally, The development of grassland animal husbandry is also of great significance. The results of the study are as follows: 1) through treadmill investigation and sample investigation, Among them, Compositae Compositaeae, Gramineaeae, Leguminosaeae are the dominant species. Leymus chinensis (Leymus chinensis) is the dominant species in the right flag of Balin, and Artemia lvaticae in the shade is 0.09280.0926, respectively. Cleistogenes caespitosa, Phragmites australis and Carex duriuscula are associated species. The relative important values of these species were 0.0763 3, 0.0751 and 0.0732.The dominant species in the left flag of Balin were Cuccinia chinensis, the associated species were Leymus chinensis, Cleistogenes songoricia) and Linumstelleroides, respectively, the relative important values were 0.0723, 0.0670,0.0656, respectively, and the dominant species in Keshiketeng flag were Cleistogenes songoricides and Linumstelleroides, respectively, and the relative important values of them were 0.0723, 0.0670,0.0656, respectively. The relative important values of Leymus chinensis, Agropyron cristatum) and Themede minor were 0. 1 128, 0. 076 9 and 0. 066, respectively, and the dominant species of Aru Korqin were Leymus chinensis with relative importance value of 0. 1059. Cleistogenes squarrosaa and Potentilla discolor) were associated species with a relative important value of 0.0670, 0.0641, 0.0517; the dominant species in Ongniute flag were Cleistogenes squarrosaa, 0.1244; Reed, Eochloa crusgaallia, Plantago asiatica. etc. The relative important value was 0.064 3 (0.0628 0. 046. 3) the diversity of grassland plant community was significantly different (P 0.01). The diversity index of grassland plant community increased first and then decreased with the increase of altitude. The diversity of plant community was the highest at the middle altitude. (4) the AHP analytic hierarchy process was used to evaluate 261 species of wild ground cover plants. The results showed that the value of exploitation and utilization of 18 species was very high, 135 species were of great value, and 57 species of wild ground cover plants had low value in development and utilization, according to the application mode of wild ground cover plants in gardens, the value of exploitation and utilization of 57 species of wild ground cover plants was lower than that of other species. In this paper, 37 species of endangered plants were found, and the protection and sustainable utilization of wild ornamental plant resources were put forward.
