【摘要】:居住區(qū)是人們生活的主要場(chǎng)所,對(duì)居住區(qū)園林植物多樣性的研究能為威海居住小區(qū)植物多樣性規(guī)劃、居住區(qū)植物景觀異質(zhì)性、城市生態(tài)系統(tǒng)多樣化提供一定的參考。本文采用網(wǎng)格法,實(shí)地調(diào)查18個(gè)居住小區(qū)的植物多樣性及其植物景觀,利用SPSS分析18個(gè)小區(qū)中社會(huì)經(jīng)濟(jì)因素與其植物多樣性的相關(guān)性,探討不同社會(huì)經(jīng)濟(jì)因子對(duì)居住綠地植物景觀產(chǎn)生的影響。研究結(jié)果如下:(1)威海居住小區(qū)綠地現(xiàn)有植物162種(含變種、變型和品種),包括64科114屬,其中裸子植物14種(隸屬于4科7屬),被子植物148種(隸屬于60科107屬)。喬木:灌木品種比為1:1.23,數(shù)量比為1:3.21;常綠植物:落葉植物品種比為1:6.14,數(shù)量比為1:2.37;喬木:花灌木:地被植物品種比為1.45:1.84:1。威海居住小區(qū)綠地植物種類以落葉植物為主,常綠植物相對(duì)較少。(2)居住綠地中,鄉(xiāng)土植物:外來(lái)植物的比例為1:1.57,外來(lái)植物比例較高,達(dá)73%。在植物種類中,薔薇科所占比例最大,其次是豆科類植物,這二者占到所有植物種類的23%,威海居住綠地景觀的相似度較高,景觀同質(zhì)化嚴(yán)重。(3)樣本小區(qū)植物整體多樣性指數(shù)方面,花灌木喬木地被植物,在小區(qū)比較方面,樣本小區(qū)中嘉祥景苑各項(xiàng)多樣性指數(shù)綜合最高,而鴻武社區(qū)和布谷夼社區(qū)因?yàn)楸容^老舊,指數(shù)為最低。(4)社會(huì)經(jīng)濟(jì)因素與居住綠地植物多樣性有一定的相關(guān)性,其中影響最為顯著的因子為綠化率。它與居住小區(qū)綠地植物生物多樣性指數(shù)顯著正相關(guān),能夠顯著直接影響居住小區(qū)綠地植物的生物多樣性。房?jī)r(jià)、容積率、物業(yè)費(fèi)與整個(gè)居住綠地植物多樣性有一定的相關(guān)性,房?jī)r(jià)與地被植物的物種豐富度顯著正相關(guān),容積率與地被植物的均勻度顯著正相關(guān),其他因素雖然與居住小區(qū)綠地的生物指數(shù)沒(méi)有顯著相關(guān),但是也與植物多樣性有一定相關(guān)性,能問(wèn)接影響著植物多樣性水平。
[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.
