Primary Research Of The Mode Of Plant Landscaping Of Residential Area

Greenland of residential areas is an important part of urban space,and the main links of improving the urban eco-environment.With the improvement of people's living standard,the greening of residential area is laid emphasis on gradually.At present, research on residential area is mainly focused on the aspects,such as designing plant scenery,planting dispositions,planting structure and ecological benefit,etc.The reach on residential plant landscape model and its evaluation system was just getting started.The area of the building of Chongqing residential areas is growing.District greening become an important link in the value of residential district.The residential area is the city's cell.A complete residential area,in addition to house,there should be supporting public service facilities,municipal project and outdoor green,and so on.The residential area greening,in addition to roads green,park green,is the largest proportion. The level of green space of the residential areas plays a direct and important role in the establishment of ecological city.There are a lot of studies on residential areas greening, but not on the residential area of plant landscape model.And although many florists has accumulated a wealth of practical knowledge in practice,the knowledge did not appear in writing,also not form a theory.So the study on residential area plant landscape model is the fisrt conclud during the last twenty years.I hope that the analysis and evaluation on residential areas of the plant landscape and the results of this study have the reference value for improving the living area of Chongqing green status,and create dependencies to habitat living environment.Second,Chongqing belongs to subtropical regions.The study on plant landscape model in Chongqing residential areas not only provide reference to residential area of Chongqing,but also have the role of radiation north and south.Namely,plant landscape model can provide referrence for the south and the north residential areas.In this paper,we carried out investigation on 19 residential areas of Chongqing metropolitan area.Tthrough a preliminary investigation,we made classification to residential area green from the perspective of plant landscape model,and took camera sampling on typical plant landscape of different types of green space.Based on the images combined with people's understanding on plant landscape of residential area green.We put forward the expression patterns of plant landscape formula,and then listed plant landscape model and plant landscape model examples of different types of green of residential areas.We used the evaluation system of landscaping to evaluate plant landscape model,and filter out "good" plant landscape model.It can provide more scientific basis for the planning and designing and construction management of residential area of green space of Chongqing city.The main research results are as follows:1.Chongqing residential areas have rich green trees,a total of 174 species,71 families,58 trees,40 shrubberies,56 kinds of herbal,and 10 kinds of plant shrubs and lawn,10 Bambooes(see appendix A).2.Based on the images and people's understanding on plants landscaping of residential area,we put afford the formula of plant landscape as follows:space/ construction→plant cultivation→form of plant life→plant species→green function→green form.3.The foundation of Plant Landscape mode system of evaluation:Evaluation of indicators used by the ecological adaptation,functional(ecological role,viewing, cultural role),plant diversity,plants and space/construction,landform,the compliance of plant form.All indicators will be given a different score.4.Through the evaluation on plants landscape model of different types of green, filtering out "good" Plant Landscape model(see 5.3).There are 125 kinds of good-degree plant landscape model,79 kinds of better-degree plant landscape model,six middle-degree plant landscape model,47 kinds of common plant landscape models. 59.5 percent are good plant landscape model.
