【摘要】：论文综合国内外省道公路绿化研究的发展趋势,以生态修复和生态美学理论为指导,先选取湖南省内4条省道公路进行调查,然后再对S322线资兴段进行重点研究,并分别对其整体景观效果、绿化植物种类及植物配置模式进行了调查分析,总结归纳出了湖南省道公路绿化现状存在的一般问题,再深入研究S322线资兴段的公路绿化现状并作出美景度评价分析,两者对比分析,由此提出了S322线公路资兴段绿化提质改造设计的策略,并将其运用到资实例中,研究成果对资兴段S322线绿化题质改造具有实践参考价值,并对类似湖南省道公路的绿化建设具有一定的借鉴价值。通过研究取得如下结果：(1)通过实地调查4条代表性省道以及资兴段S322线的公路绿化,得知湖南省道公路绿化植物主要有樟、栾树、广玉兰、杜英、刚竹、红叶石楠、红继木、山茶、苏铁、紫薇、红枫、迎春、小叶女贞、鸢尾、麦冬、吉祥草、金叶女贞、杨树、紫叶李、樱花、水杉、棕榈、杜鹃、夹竹桃、火棘、海桐等；湖南省道公路绿化普遍存在植物种类单一、配置模式简单、绿地覆盖量严重不足且缺乏管理。(2)通过美景度评价法计算得出,湖南省道资兴段322线公路绿化7种绿化带SBE平均值为：城区的行道树绿带SBEA=1.230、两侧分车绿带SBEB=1.662、路侧绿带SBEc=1.374；城外道路交叉口绿化SBED=-1.063、道路两侧绿带SBEE=1.209、边坡绿化SBEF=-1.417、屋前绿化SBEG=0.431。由结果可看出湖南省城区两侧分车绿带景观最好,其次为城区行道树绿带、城区路侧绿带；城外道路两侧绿带、屋前绿化,景观最差的是道路交叉口绿化与边坡绿化,且城区绿化明显比城外绿化好。(3)运用美景度评价法结合SPSS软件,对7种景观要素进行回归分析,分别筛选出最能影响绿化带植物景观的因子,根据相应的回归模型,得出：影响城区行道树绿化带的因子是植物形态和植物配置层次；影响城区两侧分车绿带的因子是植物形态、植物配置层次、植物多样性、植物色彩与季相；影响城区路侧绿带的因子是植物多样性、植物配置次、郁闭度；影响城外道路交叉口绿化的因子是植物多样性、植物配置层次、植物色彩与季相、郁闭度；影响城外道路两侧绿带的因子是植物配置层次、统一与变化、植物多样性；影响城外边坡绿化的因子是郁闭度、植物多样性；影响城外屋前绿化的因子是植物多样性、植物形态、植物色彩与季相、植物配置层次。因此省道公路绿化建设要根据景观要素与美景度关系模型,注重人们对省道公路绿化景观要素的偏好度。综上所述,本文主要通过运用美景度评价法对湖南省道公路城区和城外的绿化现状进行分析,通过评价结果得知湖南省城区绿化明显好于城外绿化,但总体上呈现植物种类单一,搭配形式简单,绿量不够,黄土裸露严重等问题,根据以上问题,本人提出整体、标准段与公路节点的提质改造设计策略,并将前期的研究成果运用到省道S322资兴段的实例中。
[Abstract]:The development trend of the green paper inside and outside the provincial highway in China, with the ecological restoration and ecological aesthetics theory, first select the 4 provincial highway in Hunan province were investigated, and then the S322 Zixing was focused on, and the overall landscape effect, investigated and analyzed the mode of greening plants and plants summarizes the general problems existing in Hunan Highway Greening Status, analysis of current situation of highway greening further study S322 line to Zixing and beauty evaluation, contrast analysis, put forward the highway S322 line Zixing reforming of green strategy, and apply it to the data instance, the research results have practical the transformation of the reference value of quality S322 Zixing green, and has a certain reference value for similar to the Hunan provincial highway greening construction. Through the research of node are as follows Results: (1) through the investigation of 4 representative provincial S322 line and Zixing road greening, learned that Hunan provincial highway greening plants are mainly camphor tree, Koelreuteria paniculata, Magnolia grandiflora, Phyllostachys, Du Ying, red Shi Nan, red wood, camellia, cycas, Lagerstroemia, maple, spring, small leaf privet, iris, Ophiopogon japonicus auspicious, grass, Ligustrum, poplar, purple leaf plum, cherry, metasequoia, palm, Rhododendron, oleander, Pyracantha, Pittosporum; Hunan provincial highway greening generally single plant species, configuration mode is simple, green coverage and a lack of a serious shortage of management. (2) through the SBE method calculation, Hunan provincial Zixing section 322 line highway greening 7 green belt average SBE: Urban Avenue greenbelt SBEA=1.230, both sides of SBEB=1.662 vehicle greenbelt, roadside greenbelt SBEc=1.374; SBED= Green City Road intersection -1.063, SBEE=1.209 on both sides of the road green belt, green slope SBEF=-1 .417, in front of the green SBEG=0.431. on both sides of the Hunan province urban greenbelts landscape is best, followed by the urban Avenue greenbelt, urban greenbelt of roadside greenbelt; outside the city on both sides of the road, in front of the green landscape, is the worst road intersection greening and slope greening, and city greening is more obvious than the city greening. (3) the use of scenic beauty estimation method combined with SPSS software, 7 kinds of landscape elements were selected by regression analysis, the most influencing factor with the greening plant landscape, obtained according to the regression model, the influencing factors of street trees in the green belt plant morphology and plant disposition level; impact factor is divided on both sides of urban greenbelts plant the configuration, plant level, plant diversity, plant color and seasonal factors; urban roadside greenbelt is plant diversity, plant configuration, canopy density; influence of the city outside the road intersection The fork is the green factor of plant diversity, plant arrangement and plant color and season, canopy density; impact factor outside the city on both sides of the road greenbelt plant configuration, unity and variety, plant diversity; influence factor of slope greening is outside the canopy density, plant diversity; influence factors outside in front of the house is green plant diversity, plant morphology, plant color and season, plant configuration level. Therefore the provincial highway greening construction according to the landscape elements and the beauty of the relational model, pay attention to people on the highway greening landscape preference. In summary, this paper mainly through the use of scenic beauty evaluation method on the status quo of Hunan city and the town of provincial highway through the analysis, the evaluation results of Hunan province urban greening was significantly better than the city greening, but generally shows a single plant species collocation, simple form, green is not enough The problem, loess exposed serious, according to the above problems, I put forward the overall design strategy, transformation of quality and standard section and road node, and the previous research results applied to the example in section of highway S322 Zixing.
