【摘要】：本研究對烏海市綠地植物多樣性進行了調(diào)查分析,明確了烏海市園林綠地植物種類,了解相似環(huán)境下一般城市綠地植物的種類,并對烏海市綠地植物多樣性進行了規(guī)劃。前期共調(diào)查樣地26處樣方53個,按照綠地類型可分為公園綠地、道路綠地、居住區(qū)綠地、單位附屬綠地等4類。具體地點為公園綠地調(diào)查樣地9個,分別是烏海植物園、青山翰墨園、人民公園等;道路綠地調(diào)查樣地10個,分別是海北大街、林蔭大道、海拉路等;居住區(qū)綠地調(diào)查樣地4個,分別是鉆北小區(qū)、蒙西金典花園、恒大綠洲、團結(jié)院;單位附屬綠地調(diào)查樣地3個,分別是人民醫(yī)院、烏海市政府、烏海職業(yè)技術(shù)學(xué)校。調(diào)查得到的烏海市綠地植物共有37科,68屬,108種。其中喬木植物19科,31屬,58種;灌木植物21科,34屬,46種;草本植物14科,23屬,26種。喬木中出現(xiàn)頻率較高的有垂柳、樟子松、椽柳等;灌木中出現(xiàn)頻率較高的有刺柏、水蠟、丁香等;草本中出現(xiàn)頻率較高的有馬藺、八寶景天等。四類綠地中公園綠地包含植物102種;道路綠地包含植物69種;居住區(qū)綠地包含植物26種;單位附屬綠地包含植物29種。垂直結(jié)構(gòu)類型多為喬木+灌木+草本。喬木、灌木、草本植物的Simpson指數(shù)分別為0.947、0.857、0.716,最高的是公園綠地中的喬木植物(0.943),最低為單位附屬綠地中的灌木植物(0.321)。喬木、灌木、草本植物的Margalef指數(shù)分別為7.433、3.806、1.958,最高的是公園綠地中的喬木植物(6.711)。喬木、灌木、草本植物的Shannon-wiener指數(shù)分別為3.390、2.199、1.826,其中公園綠地的喬木復(fù)雜程度最高(8.711),灌木最低(0.821)。喬木、灌木、草本植物的Pielou指數(shù)分別為0.838、0.578、0.560,單位附屬綠地的喬木層最高(0.853),單位附屬綠地的灌木最低(0.356)。綠地植物多樣性指數(shù)整體評估結(jié)果由高到低為:公園綠地道路綠地單位附屬綠地居住區(qū)綠地。分析推導(dǎo)出與烏海環(huán)境相似的沿大興安嶺、陰山、賀蘭山、昆侖山一線以西以北地區(qū)的綠地植物種類,并總結(jié)歸納烏海綠地基調(diào)樹種,及各類型綠地的骨干樹種。研究也發(fā)現(xiàn)烏海市景觀綠化如下幾個問題:鄉(xiāng)土樹種運用較少,綠化形式單一,單位附屬綠地及居住區(qū)綠地景觀綠化薄弱。應(yīng)該加強鄉(xiāng)土植物及野生種的馴化,嘗試并推廣屋頂綠化、垂直綠化、陽臺綠化等多種綠化形式,重視居住區(qū)及單位附屬綠地景觀綠化,除了在前期做好植物配置工作,還應(yīng)在后期持續(xù)管理維護。
[Abstract]:In this study, the diversity of green space plants in Wuhai City was investigated and analyzed, and the species of green space plants in Wuhai City were clarified, and the species of general urban green space plants in similar environment were understood, and the diversity of green space plants in Wuhai City was planned. In the early period, there were 53 sample plots in 26 sample plots, which could be classified into four types according to the types of green space, such as park greenbelt, road green space, residential area green space, unit subsidiary green space and so on. The specific sites are 9 sample sites of park green space investigation, such as Wuhai botanical garden, Qingshan Hanmo garden, people's park, etc., and 10 sample sites of road green space investigation are Haibei street, tree-lined avenue, Haila road and so on; There are 4 sample plots of green space investigation in residential area, which are Jingbei district, Jindian garden, Hengda oasis, unity institute, and 3 sample plots of affiliated greenbelt, which are the people's hospital, the government of Wuhai city and the Wuhai vocational and technical school There are 108 species of green plants belonging to 68 genera and 37 families in Wuhai. Among them, there are 58 species of Arbor plants belonging to 19 families and 31 genera, 46 species of shrub plants belonging to 34 genera and 21 families, and 26 species of herbaceous plants belonging to 14 families, 23 genera and 23 genera. Among the trees, there are weeping willow, Pinus sylvestris, rafter willow and so on; in the shrub there are thorns, water wax, clove, etc. There are 102 species of plants in park greenbelt, 69 species in road greenbelt, 26 species in residential green space and 29 species in unit affiliated greenbelt. The vertical structure type is mostly Arbor and shrub herbaceous. The Simpson index of Arbor, shrub and herbaceous plants were 0.947 (0.857) and 0.716, respectively. The highest Arbor (0.943) was the highest, and the lowest (0.321) was the shrub. The Margalef index of Arbor, shrub and herbaceous plants was 7.4333.806 / 1.958, respectively, and the highest was Arbor (6.711). The Shannon-wiener index of Arbor, shrub and herbaceous plants were 3.390, 2.1991.826, respectively. Among them, the complexity of Arbor was the highest (8.711) and the shrub was the lowest (0.821). The Pielou index of Arbor, shrub and herbaceous plants was 0.838% 0.578U 0.560, respectively. The Arbor layer was the highest (0.853) in the unit attached green space and the lowest (0.356) in the unit subsidiary greenbelt. The overall evaluation results of green plant diversity index from high to low are: Park greenbelt road greenbelt unit attached green district green space. This paper analyzes and deduces the species of green space plants along the north of Daxing'an Mountains, Yinshan Mountains, Helan Mountains and west of Kunlun Mountains, which are similar to the Wuhai environment, and sums up the key tree species of Wuhai greenbelt and the key species of various types of greenbelts. The study also found the following problems of landscape greening in Wuhai City: less use of native tree species, single form of greening, and weak landscape greening of unit affiliated green space and residential district green space. We should strengthen the domestication of native plants and wild species, try and promote various greening forms, such as roof greening, vertical greening, balcony greening, etc. It should also be maintained at a later stage.
