The Study On The Three Dimensional Green Biomass Of Five Kinds Of Common Garden Plants In Kangbashi District Of Ordos City

In recent years, with the development of the city and put forward the "vigorously promote the construction of ecological civilization of strategic decision, how fast and effectively improve urban ecological environment has become an important problem of urban development. Garden plant with regulating urban microclimate, improving the urban ecological environment effect, is a part of urban ecological system construction essential. Therefore, the master of urban garden plant of 3D green quantity to become an important factor in the evaluation of urban ecological environment. Due to different tree species with different growth habits and morphological characteristics, resulting in the three-dimensional green biomass differences exist, thus affecting the ecological benefits of exertion. In the working process of the garden, how in the crowd Intensive urban environment to improve the utilization rate of green space and the three-dimensional green amount of garden plants, so as to play its proper ecological benefits, is the problem faced by each landscape workers.This study choose Ordos City Kangbashi district greening commonly used five kinds of garden plants as the object of study, of parks in the urban areas and major roads such as landscape plants of different green space of 3D green quantity measurement, derived from different plant species of 3D green quantity index, and measured the plant height, crown diameter and diameter at breast height, crown higher morphological index and tridimensional green biomass were correlation analysis, in order to calculate the regression equation of the five species of 3D green quantity calculation and tridimensional green biomass and leaf area index were compared, the correlation analysis between the two. Main research results are as follows:(1) Establish the Ordos City Kangbashi District of Sophora japonica, Salix matsudana, Fraxinus pennsylvanica, Ulmus pumila cv.jinye. Gleditsia sinensis, these five kinds of common garden plants of the regression equation.(2) The five species of three-dimensional green biomass and leaf area index of correlation analysis obtained tridimensional green biomass and leaf area index has a high correlation, the correlation coefficient:Salix matsudana (0.86)> Sophora japonica (0.84)> Ulmus pumila cv.jinye (0.83)> Fraxinus pennsylvanica (0.81)> Gleditsia sinensis (0.62). Thus, with the increase of tree canopy density, species of 3D green quantity is also on the rise. Five species of average 3D green quantity:Gleditsia sinensis (27.15m3)> Fraxinus pennsylvanica (17.62m3)> Sophora japonica (15.34m3)> Ulmus pumila cv.jinye (9.35m3)> Salix matsudana (5.92m3). And five kinds of The average leaf area index of species:Fraxinus pennsylvanica (8.68)> Sophora japonica (7.84)> Gleditsia sinensis (2.80)> Ulmus pumila cv.jinye (2.32)> Salix matsudana (1.28).(3) According to the method of this study, correlation analysis of morphological characters of each species and tridimensional green biomass, of other species in Landscape Application of tridimensional green biomass regression equation can be established, so as to provide more theoretical basis in the Kangbashi district landscape plant configuration.
