The Plant Ecological Arrangement Changchun Residential Quarters

In this article,the plant arrangement of Changchun residential quarters at present,theplant arrangement of man-made forest in the South Lake and the plant arrangement of naturalforest is investigated and studied。And the pattern of the plant arrangement Changchunresidential quarters is raise by analyzing above three plant arrangement base on ecologicaltheory:(1)The environmental construction of Changchun residential quarters should be based onbuilding garden by planting: reducing usage of concrete landscape,planting vegetation .As resultit is economic ,novel and ecological to construct environment like that.(2)The plant arrangement should embody change of season color :stress springflower,summer leaf,autumn fruit,winter trunk,come up to the beautiful landscape in everyseasons by arranging reasonably.(3)Increase abundance of plant:at present,the plant variety being applied inChangchun residential quarters is not more than 40,but in fact more than 100 plant varietycan be used,and more local plant not being used. Undoubted it is a waste to plant resource.(4)Increase change of plant height and plant layer:at present,the plant arrangementis plane,it is very poor at ecology .we must increase plant height and plant layer ,thus thelimit space can be used efficiently ,the using effect of the land can be enhanced.(5)The arrangement both side of the road should depend mainly on the big crown ofthe tree,screening the road of the residential quarters from the strong ways.( 6 ) The arbor like Populus canadensis , Fruxinus mandshurica , Juglansmandshurica etc. can be planted in the green land of around the residential quarters andsquarer ,these trees are well both on visual effect and on the ecological effect.(7)Vine-tree,vine plant can be used in green land of the underground-garage,do ourbest to enhance green space.(8)Make sufficient use of the residential roof,construct roof garden :roof garden iscovered green vegetation and provided facilities of water supply and drainage. It can insulateheat,preserve heat,purify atmosphere,separate noise,absorb dust,increase oxygen,as aresult it enhance life quality. Not only ecological roof can increase green area,but also keepnature balance,reduce warm-island effect.
