Artificial Wetland Spatial Construction Mode And Landscape Design Improvement In North Piedmont Of Qinling Mountain

With the rapid development of urbanization and the increase of population density,the contradiction between man and nature has become increasingly prominent,especially the safety of water environment.The accumulation of population have greatly increased the risk of regional water security,and also brought water pollution problems.Especially in the suburban environment and rural environment,domestic sewage and industrial sewage are discharged into the natural water bodies,causing pollution of the water and the ecolo gical deterioration.This is the case in the northern piedmont of Qinling Mountains.Artificial wetland has the advantages of low cost,not only can purify sewage,improve the environment,ecological system as a kind of high ecological service function,but also can provide habitats for organisms,forming a beautiful natural environment,and whenever the natural beauty always has rich tourism value.However,in wetland practices,there have been many problems.First of all,small suburban environment and the countryside environment for the construction of artificial wetland construction lack clear guidelines,causing many type sewage treatment type artificial wetland water purification efficiency cannot meet the process requirements.Secondly,water purification type artificial wetland in half natural environment of natural ecological system may have a certain risk,and need more environmental impact analysis.Finally,artificial wetland water purification is functional wetland,which result of the population and have obvious influence on rural culture,residential landscape,the landscape construction of research on artificial wetland treatment also have a lot of blank.Based on the above background,the ways of artificial wetland pla nning and landscape design processing strategies suitable to the north region of Q inling Mountains are as explored in this paper by study collection,field surveys,expert interviews,data analysis and other methods.The current situation and problems of manual disposal of wetlands at the northern piedmont of Q inling Mountains is identified and analyzed.And the space construction model and landscape design promotion method s of Q inling Mountains constructed wetland are summed up.In this paper,the study of Q inling effect in artificial wetland treatment is divided into three parts,the first part studies the effect of artificial wetland in Q inling,through to the Q inling effect in artificial wetland types and distribution of carding,northern area of Q inling clearly the status quo of the artificial wetland treatment cases,and by comparison and analysis in this paper,the main research object,Chang 'an Shangwang village on the artificial wetland treatment.The second part of Shangwang village artificial wetland treatment on C hangan area identified and cause analysis,and carried out on the Shangwang village on the surrounding environment.The last part of the above the Shangwang village artificial wetland as an example,discusses the effects of artificial wetland landscape in Q inling construction strategies and methods,and refine the northern region of Q inling spatial patterns of artificial wetland treatment.This paper innovation points: O ne is in terms of content,breaking the previous studies on wetland plant configuration mode,as the angle of view,but from the point of view of the spatial pattern of wetland,put forward suitable for Q inling Mountains in northern area of artificial wetland treatment "source sink" space model;Two,in the object aspect,select the small man-made wetland as the object,and discuss the strategy and method of landscape construction of the artificial wetland in the north foot of Qinling Mountains;The three is to clear the status of manual handling case of artificial wetland types and distribution in Q inling Mountains and various,and to regard artificial treatment wetland in C hangan District as a typical case,the current problems and the causes are analyzesed.
