【摘要】：本研究对乌海市绿地植物多样性进行了调查分析,明确了乌海市园林绿地植物种类,了解相似环境下一般城市绿地植物的种类,并对乌海市绿地植物多样性进行了规划。前期共调查样地26处样方53个,按照绿地类型可分为公园绿地、道路绿地、居住区绿地、单位附属绿地等4类。具体地点为公园绿地调查样地9个,分别是乌海植物园、青山翰墨园、人民公园等;道路绿地调查样地10个,分别是海北大街、林荫大道、海拉路等;居住区绿地调查样地4个,分别是钻北小区、蒙西金典花园、恒大绿洲、团结院;单位附属绿地调查样地3个,分别是人民医院、乌海市政府、乌海职业技术学校。调查得到的乌海市绿地植物共有37科,68属,108种。其中乔木植物19科,31属,58种;灌木植物21科,34属,46种;草本植物14科,23属,26种。乔木中出现频率较高的有垂柳、樟子松、椽柳等;灌木中出现频率较高的有刺柏、水蜡、丁香等;草本中出现频率较高的有马蔺、八宝景天等。四类绿地中公园绿地包含植物102种;道路绿地包含植物69种;居住区绿地包含植物26种;单位附属绿地包含植物29种。垂直结构类型多为乔木+灌木+草本。乔木、灌木、草本植物的Simpson指数分别为0.947、0.857、0.716,最高的是公园绿地中的乔木植物(0.943),最低为单位附属绿地中的灌木植物(0.321)。乔木、灌木、草本植物的Margalef指数分别为7.433、3.806、1.958,最高的是公园绿地中的乔木植物(6.711)。乔木、灌木、草本植物的Shannon-wiener指数分别为3.390、2.199、1.826,其中公园绿地的乔木复杂程度最高(8.711),灌木最低(0.821)。乔木、灌木、草本植物的Pielou指数分别为0.838、0.578、0.560,单位附属绿地的乔木层最高(0.853),单位附属绿地的灌木最低(0.356)。绿地植物多样性指数整体评估结果由高到低为:公园绿地道路绿地单位附属绿地居住区绿地。分析推导出与乌海环境相似的沿大兴安岭、阴山、贺兰山、昆仑山一线以西以北地区的绿地植物种类,并总结归纳乌海绿地基调树种,及各类型绿地的骨干树种。研究也发现乌海市景观绿化如下几个问题:乡土树种运用较少,绿化形式单一,单位附属绿地及居住区绿地景观绿化薄弱。应该加强乡土植物及野生种的驯化,尝试并推广屋顶绿化、垂直绿化、阳台绿化等多种绿化形式,重视居住区及单位附属绿地景观绿化,除了在前期做好植物配置工作,还应在后期持续管理维护。
[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.
