Application and Adaptability of Ornamental Grasses in Road Flower Borders in Hefei, Anhui Province

In-depth research was conducted on the types,seasonal patterns,spatial levels,overwintering,summering,drought resistance,and disease and pest resistance of ornamental grasses in the road flower borders of Hefei,Anhui Province.Through field investigations,a total of 36 ornamental grasses were identified,with Liliaceae having the most species and the Lamiaceae the least.The results show that there are more warm season ornamental grasses,of 23 species;Acorus gramineus and Melinis minutiflora have poor overwintering ability;Arrhenatherum elatius,Festuca glauca,and Stipa tenuissima have poor summer tolerance;most ornamental grasses have strong drought resistance and resistance to pests and diseases.The comprehensive investigation shows that ornamental grasses have good application prospects and adaptability in the road flower borders in Hefei city.

AHP-based Landscape Value Evaluation of Perennial Flower Border Application in Hefei City

An analytic hierarchy process(AHP)was employed to establish a landscape value evaluation model for 20 common species of perennial flowers in the flower border of Hefei City.With the overarching objective of determining the application value of the flower border,10 evaluation factors were identified and subsequently classified into 3 distinct grades.Grade I(L>2.5)was defined as perennial flower resources with the highest development and utilization value,including only one species of Salvia farinacea.Grade II(2.0≤L≤2.5)was defined as perennial flower varieties suitable for most areas,encompassing 9 species of plants,such asTaraxacummongolicum.Grade III(L<2.0)was defined as perennial flower varieties with low application value,encompassing 10 species of plants,such asRuellia brittoniana,but lacking the value of further popularization and application.Consequently,the proportion of their application in the flower border should be reduced.The evaluation results can serve as a theoretical foundation for the implementation of perennial flowers in urban flower borders.

Application of Flower Borders in Hefei City

The application value of 70 kinds of flowers in Hefei City was evaluated by analytic hierarchy process(AHP).From the three aspects of adaptability,ornamental value and economic traits,12 indicators were summarized to establish a comprehensive evaluation system.The results show that the application of grade-I plants(J≥3.6642)in flower borders is the most suitable,and they include 19 species of plants such as Osmanthus fragrans var.thunbergii,accounting for 27.14%.The application of grade-II plants(3.2319≤J≤3.6641)in flower borders is suitable,and 36 species of plants such as Jacobaea maritima are included,with the proportion of 51.42%.The application of grade-III plants(2.7935≤J≤3.2318)in flower borders is relatively suitable,and they contain 8 species of plants such as Acer palmatum’Atropurpureum’(Van Houtte)Schwerim,accounting for 11.42%.Grade-IV plants(J≤2.7934)can be applied in flower borders under special circumstances,and include 6 species of plants such as Muehlenbeckia complexa Meisn.,accounting for 8.57%.The results can provide reference for the selection of flower border plants in Hefei.The locations and types of 40 flower borders were summarized to provide a basis for the development direction and future planning of flower borders in Hefei.

Application of Flower Border at Senlinyicheng Residential District in Qinhuangdao City

花境植物固碳能力及碳收支评估

花境在城市绿地中的应用越来越广泛,但花境的碳汇效益仍然存在争议。为评价和预测花境的碳收支效益提供科学依据,基于对植物固碳量和群落碳收支的测算,以天津市常见的50种花境植物和5个花境样地为例,构建花境群落碳收支评估模型,评估并模拟花境的碳收支情况,分析花境碳收支与碳排放活动、群落特征之间的关系。结果表明:1)一年生植物与多年生植物的年固碳量平均值近似,高固碳植物有硫华菊、柳枝稷、月季等15种;2)由于运输碳排放较高等原因,大部分实际营造的花境仍是碳源;3)花境的碳汇效益受植物固碳能力、植物生活型比例、花境面积、运输距离、更新频率等多重因素影响。3)合理配置的花境能够在3~5年内实现碳平衡。最后针对研究存在的不足提出展望,即还需更多样本来验证结论,花境的长期碳收支预测应考虑更多的影响因素,以及生态效益评估应与经济效益、美学价值相结合。

不同时空情境下杭州市城市花境植物与访花昆虫间的相关性

随着城市化进程的快速推进,城市绿地生态系统在高密度环境中的保护功能、美化功能、文化游憩等服务价值研究具有重要意义。应用样方法对杭州市城市花境植物物种和访花昆虫物种进行现状调研,计算其物种丰富度指数和多样性指数,并通过不同时空情境下植物与访花昆虫的相关性分析解释花境植物组成对访花昆虫种类与数量的影响。调查结果显示:在杭州城市花境中常用植物共计132种,隶属63科115属;访花昆虫以蝇类、蜂类、蝶类、蛾类和其他5大类为主。蜂类在各时段的访花频次高于其他访花昆虫类型;低不透水面密度花境开花植物种数和访花昆虫多样性均高于中高不透水面密度花境;秋季访花昆虫的访花频次高于春季和夏季访花昆虫。城市区域内不透水面密度是影响花境中植物物种结构和访花昆虫种类的重要因素。根据城市花境生境条件,对营建访花昆虫友好型的城市花境植物配置提出可行性建议,从而为城市生物多样性保护与利用提供科学依据。
