【摘要】：居住区是人们生活的主要场所,对居住区园林植物多样性的研究能为威海居住小区植物多样性规划、居住区植物景观异质性、城市生态系统多样化提供一定的参考。本文采用网格法,实地调查18个居住小区的植物多样性及其植物景观,利用SPSS分析18个小区中社会经济因素与其植物多样性的相关性,探讨不同社会经济因子对居住绿地植物景观产生的影响。研究结果如下：(1)威海居住小区绿地现有植物162种(含变种、变型和品种),包括64科114属,其中裸子植物14种(隶属于4科7属),被子植物148种(隶属于60科107属)。乔木：灌木品种比为1：1.23,数量比为1：3.21；常绿植物：落叶植物品种比为1：6.14,数量比为1：2.37；乔木：花灌木：地被植物品种比为1.45：1.84：1。威海居住小区绿地植物种类以落叶植物为主,常绿植物相对较少。(2)居住绿地中,乡土植物：外来植物的比例为1：1.57,外来植物比例较高,达73%。在植物种类中,蔷薇科所占比例最大,其次是豆科类植物,这二者占到所有植物种类的23%,威海居住绿地景观的相似度较高,景观同质化严重。(3)样本小区植物整体多样性指数方面,花灌木乔木地被植物,在小区比较方面,样本小区中嘉祥景苑各项多样性指数综合最高,而鸿武社区和布谷夼社区因为比较老旧,指数为最低。(4)社会经济因素与居住绿地植物多样性有一定的相关性,其中影响最为显著的因子为绿化率。它与居住小区绿地植物生物多样性指数显著正相关,能够显著直接影响居住小区绿地植物的生物多样性。房价、容积率、物业费与整个居住绿地植物多样性有一定的相关性,房价与地被植物的物种丰富度显著正相关,容积率与地被植物的均匀度显著正相关,其他因素虽然与居住小区绿地的生物指数没有显著相关,但是也与植物多样性有一定相关性,能问接影响着植物多样性水平。
[Abstract]:Residential area is the main place for people to live. The study of landscape plant diversity in residential area can provide some references for planning plant diversity, plant landscape heterogeneity and urban ecosystem diversification in Weihai residential area. In this paper, the plant diversity and plant landscape of 18 residential areas were investigated by grid method, and the correlation between social and economic factors and plant diversity was analyzed by SPSS. To explore the influence of different social and economic factors on plant landscape of residential green space. The results are as follows: (1) there are 162 species of plants (including varieties, forms and varieties, including 64 families, 114 genera, 14 species of gymnosperms (belonging to 4 families, 7 genera) and 148 species of angiosperms (belonging to 107 genera, 60 families) in Weihai. Arbor: shrub ratio is 1: 1.23, quantity ratio is 1: 3.21; evergreen: deciduous plant variety ratio is 1: 6.14, number ratio is 1: 2.37; Arbor: flower: shrub: ground cover plant variety ratio is 1.45: 1.84: 1. The proportion of native plants: exotic plants is 1: 1.57, the proportion of exotic plants is higher, and the proportion of exotic plants is 73. Among the plant species, Rosaceae accounts for the largest proportion, followed by legumes, which account for 23% of all plant species. The similarity of the landscape of Weihai residential green space is high. Landscape homogenization. 3) on the whole diversity index of plants in the sample plot, the flowering and shrub Arbor cover plants, in the plot comparison, the comprehensive diversity index of Jiaxiangjing Garden was the highest in the sample plot. In Hongwu and Bugukuang communities, the social and economic factors have a certain correlation with the plant diversity of residential greenbelt because they are old and the index is the lowest. Among them, the most significant factor is the green rate. It has a significant positive correlation with the biodiversity index of green space plants in residential areas and can directly affect the biodiversity of green plants in residential areas. There was a positive correlation between house price, floor area rate, real estate cost and plant diversity of the whole living green space, and there was a significant positive correlation between house price and species richness of ground cover plant, and between floor area rate and evenness of ground cover plant, and there was a significant positive correlation between housing price and plant diversity. Other factors were not significantly related to the biological index of green space, but also related to plant diversity, which could affect the level of plant diversity.
