Research On The Applications Of Bamboos In Modern Garden

234 literatures regard as bamboo designing which could be referred were read at first, then methods such as assay,induction and sthenia syndrome were used to analyze 23 domestic and abroad bamboo designing cases deeply,especially 10 of the total cases were actual measured,investigated and researched.Photosynthesis of 16 bamboo species including Bambusa glaucescens,Phyllostachys aurea'Luteosulcata',Sasa fortunei,Sasa palmate ssp.neblosa,Phyllostachys aurea'Viridisulcata',Hibanobambusa tranquillans 'Shirosima',Pleiobalstus hindsii,Phyllostachys nigra,Phyllostachys bambusoides 'Albo-variegata',Ph.aureosulcata'Spectaabilis',Sinobambusa tootsik,Phyllostachys bambusoides sp.,Phyllostachys vivax 'Aureocalis',Pleioblastus gramineus,Sasa auricoma and capability of lowering noise of 10 bamboo species including Phyllostachys pubescens,Bambusa glaucescens,Phyllostachys nigra,Pseudosasa amabilis,Phyllostachys aureosulcata'Spectabilis',Pleioblastus gramineus,Hibanobambusa tranquillans'shirosima',Phyllostachys aurea'luteosulcata',Phyllostachys aurea 'Viridisulcata',Sasa argenteastriatus were tested.Based on this,the specificity of bamboo designing which was reflected in modern landscape was researched technically and further the application and practice was carried out through 2 specific case,main conclusion was concluded as follow:1,The species of bamboo was as many as 1200 and the ecological type and genetic diversity were also abundant.Along with further modern bamboo research,bamboo designing had more ecological consciousness,to imitate the nature also had more abundant meaning and advanced methods.The application of bamboo designing in modern garden was not only contribute artificial plant community building,but also widening engineered visual field in the area of protection of biological diversity;2,Bamboo has more apparent dominance than other common plants at ecological benefit aspect though the quantization study.Through the test of photosynthesis of 16 bamboo species,it was indicated that the photosynthetic rate of Bambusa glaucescens was the highest at the same conditions,the photosynthetic rate of Phyllostachys bambusoides sp.,Sinobambusa tootsik,Phyllostachys bambusoides 'Albo-variegata',Phyllostachys vivax 'aureocaulis',Pleiobalstus hindsii were fairly low;Light compensation point,light saturation point and Max CO₂ absorbing capability could be calculated through photoresponse curve,it was indicated that the CO₂ absorbing dose of Bambusa glaucescens and Phyllostachys aurea'luteosulcata'were the largest,the CO₂ absorbing dose of Pleiobalstus hindsii,Phyllostachys nigra,Phyllostachys bambusoides 'albo-variegata',Phyllostachys bambusoides sp.,Sinobambusa tootsik andPhyllostachys vivax 'aureocaulis' were relative low;the magnitude of light saturation point explained that the capability to use subdued light of Pleioblastus gramineus and Phyllostachys bambusoides'Albo-variegata'were strong,they were suit to raise in the circumstance of low light intensity,the capability to use subdued light of Pleiobalstus hindsii and Sinobambusa tootsik were weak,they were not suit to raise in the circumstance of low light intensity;the magnitude of light saturation point could indicate that the anti-solarization of Sinobambusa tootsik and Sasa auricoma was strong,and the anti-solarization of Phyllostachys bambusoides sp.and Phyllostachys bambusoides'Albo-variegata'was weak.The test of lowering noise of 10 bamboo species indicated that the effect of lowering noise of different bamboo forest species was different.Among them,the effect of lowering noise of Sasa argenteastriatus was the best,the noise attenuation coefficient achieved 11.5 dB,and the effect of lowering noise of forest was better than open space apparently.The further service of bamboo designing was thought more and more highly nowadays which further urbanization and more draconic attenuation coefficient approached.Original thought emphasized that bamboo designing not only applied recreated environment,but also handled with environment through more affluent methods,turned into modern society initiatively,embodied new era thinking and civilization.3,For most gardens,bamboo designing had to give consideration to the balance among 4 aspect including natural regularity,social function,visual landscape and cultural artistic conception.However,the main confliction of various times and spaces,then the key problem to solve was also different,therefore,the transformation of modern bamboo designing was a various and consummating process advanced with times and spaces.There was a tradition in our country to advocate nature and emphasis civilization in bamboo designing,and the positive research of devising thinking and reformation of methods were also approached in recent several decades.The march of modernization was started before long,the further development of bamboo designing would be a heavy burden and long road.
