Baoding Road Greening Tree Species And The Ecological Benefitevaluation Configuratiomode

In this paper, the main greening tree species of baoding city and its main greening configuration mode to study the ecological benefits, first studied the various tree species and the configuration mode of green rate, and quantitative study respectively the greening tree species unit leaf area and green area ecological benefits, on the basis of quantitative study the different plant configuration mode of greening benefit per unit area. Provide the basis for road greening. Main conclusions are as follows:Road greening tree species and afforestation pattern green quantity aspect: trees, shrubs, differences, there are certain differences between trees and shrubs. Green quantity rate value comparison between trees, the order is: sycamores > Sabina chinensis > acer truncatum > weeping willow > goldenrain tree > ginkgo locust > acacia>poplar > pagoda tree > tree of heaven. Order quantity of green rate is between shrubs:Virginia creeper > torch tree > flowering plum > forsythia > clove > leaf privet >jin take > kerria japonica > big leaves huang Yang > abundant flowers rose; Main greening model green flow rate per unit area value comparison, the order is: J > A > B > D > C > H > E> G > I > F.Road greening tree species ecological aspects: each species unit leaf area and green area various significant ecological benefits. Tree species of afforestation benefits by the tree itself characteristics and quantity of green rate, unit leaf area of ecological benefit and green area of various ecological benefit is not completely consistent. Every sort of tree species main ecological functions are as follows: per unit leaf area of carbon sequestration of trees release oxygen function sort of acacia > goldenrain tree > scholar > plane trees> peels ginkgo > Sabina chinensis, units green area function of carbon oxygen release sort to acacia >goldenrain tree>plane trees> peels pagoda tree >ginkgo > Sabina chinensis; Per unit leaf area of shrub carbon sequestration ability to release oxygen sorting for abundant flowers rose > gold leaf privet > big leaf by huang >Virginia creeper, unit capacity release oxygen green area sorting for the Virginia creeper>gold leaf privet > big leaf by huang > abundant Chinese rose flower. Dust detentions per unit leaf area of tree sort is: Sabina chinensis > poplar > pagoda tree > tree of heaven > goldenrain tree > weeping willow, dust detentions unit green area order: the delinquencies hodginsii > poplar > pagoda tree >goldenrain tree > tree of heaven > weeping willows. Dust detentions per unit leaf area of shrub order:clove >jin take > flowering plum > kerria japonica, dust detentions unit green area order: clove > jin take >flowering plum >. Trees absorb SO2 unit leaf area far absorbed is poplar > killers hodginsii > weeping willow > plane trees> peels gongxieli, units for green area order uptake was poplar > killers hodginsii >plane trees> peels weeping willow > gongxieli; Shrubs unit leaf area sulfur absorption sort of big leaf by huang > gold leaf privet > Chinese redbud, units green area sulfur absorption ability is great in huang Yang > gold leaf to leaf privet > Chinese redbud.Main road greening greening patterns ecological aspects: 10 types of plant configuration mode tree configuration, shrubbery, configuration type, and there is a difference between and among shrubs configuration type. But overall, the three types of configuration is overall benefit tree configuration type configuration types > shrub > shrubbery configuration type. Each configuration type main ecological functions of sorting as follows: plant carbon sequestration capacity results in from big to small order: tree configuration type J > A > C; In the shrubbery, configuration type B > E> D> F; I> G >H in the shrub configuration type. Plant ability to release oxygen measurement results compliance to small order greatly for: tree configuration type J > A > C; In the shrubbery, configuration type B > E> D > F; I> G > H in the shrub configuration type. Dust detentions plant calculated result according to the order from large to small:tree configuration type J > A > C; In the shrubbery, configuration type E > D > B > F; >> I G H in the shrub configuration type. Plants absorb SO2 capacity calculated result according to the order from large to small: tree configuration type C>a.>J; In the shrubbery, configuration type D >B >E> F; I> G> H in the shrub configuration type. Plant humidifying capacity calculation result according to the order from large to small: tree configuration type J > A > C; In the shrubbery, configuration type B > D > F > E; shrub in the configuration type G >H>I. Plant cooling capacity calculated result according to the order from large to small: tree configuration type J > A > C; In the shrubbery, configuration type B > D > F> E; shrub in the configuration type G> H >I. Plants absorb Cl2 ability calculated result according to the order from large to small: J C > A > tree configuration type; In the shrubbery, configuration type E > D > B > F; Shrubs G>H> I configuration type. Plants absorb HF ability calculated result according to the order from large to small: tree configuration type J > A > C; In the shrubbery, configuration type B > D >F > E; Shrubs G>H>I configuration type. Plant sterilization ability calculated result according to the order from large to small:tree configuration type J > A > C; In the shrubbery, configuration type B > D > F> E; I > H> G in the shrub configuration type. Plant noise reduction ability calculated result according to the order from large to small: tree configuration type A > J > C; In the shrubbery, configuration type D > B > F> E; I >G> H in the shrub configuration type.
