Comprehensive Analysis And Research On Design Concept And Instance Of River Landscape In Hohhot

In Hohhot to determine the amount of green trees,the Hohhot garden greening tree species selection of scientific significance,precise calculation of green quantity of Hohhot greening planning and green space ecological benefit evaluation provides a reliable basis.Acer truncatum,catalpa tree,tree,acacia,ailanthus deciduous broadleaf tree species as the main tree species of Hohhot city landscaping,landscape ecological environment of Hohhot city virescence and improve plays an important role.The study on green quantity of these deciduous broadleaf trees is an important index to measure their ecological benefit.The green quantity is an index to evaluate urban green space,which can make up for the deficiency of the two dimensional green indexes.This paper introduces the concept of green quantity and discusses the purpose and significance of green quantity and the application of green quantity.The most widely used,the most extensive and representative of 10 deciduous broadleaf tree species in Hohhot were selected as the research object.The tree species of 10 deciduous broadleaf trees are: yuanbaofeng,zi tree,locust,white wax,silk cotton,acacia,tree of heaven,peach,torchbearer and dragon.Field measurement was carried out according to selected 10 deciduous broadleaf tree species.Determine the shape of the 10 kinds of deciduous broadleaf tree species of tree crown and formulas and the calculation method of green quantity,through to the Hohhot 10 kinds of deciduous broadleaf tree species of the crown,diameter at breast height,tree higher between data and the analysis of the correlation of the green,it is concluded that with deciduous broadleaf tree species of green quantity is the most relevant crown breadth and height.Based on the correlation between green volume and canopy and tree height,a linear regression equation of green quantity and canopy curve fitting equation and green volume,crown width and tree height were established for 10 deciduous broadleaf tree species.The appropriate regression equation model can be selected according to the actual needs.If the tree species in a certain green space in a city are investigated,the best model of green quantity can be calculated.If a large area of green space in a city is investigated,the binary linear regression equation with high precision can be selected for calculation.
