The Assessment Of Benefit Of Rural Residential Environment Greening And Its Landscape Design

Residential environment greening in rural areas is an important component of national land greening and the rural ecological civilization.It's also main foundations of the sound development of rural ecological environment ecology.It has active roles in improving quality of rural life and enhancing the competitiveness of rural areas. At present, because the human irrational model of development has degraded the environment , more and more people consider to recognize these problems, that the greening has great importance in improving the ecological environment and creating high-quality living environment on the overall efficiency. In this study taking the new socialist countryside construction of "Let the village clean and tidy" as breakthrough ,Linghe Town's residential environment greening as a target.The paper used the analysis of application-level analysis, expert consultation law, the value of alternative and multi-objective decision-making method to evaluate the residential environment. The main conclusions are as follows:1) Evaluation benefit of greening tree species in rural living environment According to investigation and analysis of rural living environment in Linghe town , the authors selected 40 kinds of main greening tree species including 10,842 objects which determined their evaluation benefit such as cooling, humidifier, lowering wind speed, carbon sequestration, release oxygen ,absorption SO₂ and noise reduction.The results showed that: In the cooling aspect, the most obvious role is deciduous broad-leaved trees, followed by evergreen coniferous trees, shrubs species is the weakest; in the Dust aspect, the relationship among roughness, petiole length and Health angle of plant leaf had large differences, evergreen coniferous trees'Dust capacity was significantly, with an average of Dust 1.143mg/cm².d; deciduous broad-leaved tree Dust capacity slightly larger than the shrubs in general, reaching 0.857mg/cm².d, shrubs average of Dust 0.714mg/cm².d; in the release oxygen and carbon sequestration aspect, the broad-leaved trees had the best effect, shrubs had the smallest effect on carbon sequestration and oxygen release, conifer's capacity between the first two; in the absorption of SO2 and reduce noise aspect, green plants especially deciduous broad-leaved trees has a strong role in the absorptive SO₂ and noise reduction, the effect is better than shrubs, the effects of conifers is the worst. To sum up, in the deciduous broad-leaved tree species such as poplar, willows and S.japonicaL.f·pendulaLoud had significant overall efficiency;in the evergreen conifer species, picea ,Platycladus orientalis and Pinus tabulaeformis performed best; in the shrubs species , Syringa oblata, Prunus triloba and purple leaf barberry had the best benefits.2) Evaluation benefit of models green in rural New living environmentIn this paper, the main research was about four major types of rural living environment's comprehensive green-effective evaluation and landscape design.The main green space types include: courtyard green, The surounding protective forest, street greenbelt and street garden, this paper give the four types of garden a comprehensive evaluation with eco-efficiency, social and economic benefits analysis. Among them, through the investigation the courtyard green space has produced a pattern of seven kinds of green, and through qualitative and quantitative results showed that the Park Essay type has the best benefits on increasing the vertical greening area and regulating other environmental factors, The Eco-tourism type is second, moreover, it can solve the countryside employment problem efficiently; The other five types are Natural greening type > Fruits and vegetables concurrently type > Wood and fruit tree type > Flower and vegetable garden type > Practical drying yard type; The surounding protective forest sums up the four kinds of green mode, in which the nursery and forest type have better economic and ecological benefits they would become new rural models of green building; street greenbelt has four kinds of green space, each model of the road due to geographical location and its own unique features and different levels. The landscape model which both has the forest-based protection, landscape and the functional requirements of transportation, is more worthy to promote; The new rural street garden is the main venues to villagers outdoor, the main green space is divided into three kinds of patterns, recreation belt model, fitness site mode and leisure entertainment, among them the recreation belt model has higher efficiency.3) Landscape design of rural living environmentAt the same time, through the investigation and research of new rural areas'green living environment in Linghe town Weifang City Shandong Province, This paper presents a new analysis of landscape design combined with landscape ecology, native landscape planning theory, urban and rural integration and principles of landscape design. Take Xinli Village as an example, a variety of optimization models are applied to new construction in rural areas'green environment, in order to show a specific new living environment in rural areas clearly. And the resulting rural development in the new living environment to create a green-effective classification system and comprehensive evaluation method is feasible, but in view of the construction of new countryside and wide-ranging differences, the authors study the level of their own limitations and lack of experience, such classification system, evaluation methods and the landscape design of the specific role of guiding significance and requires further in-depth study.
