Description
Technical field
The present invention relates to town plannings, more specifically, it relates to a kind of urban ecological planning partition method and system.
Background technique
Ecological planning is applied ecology principle, using living environment's Sustainable Development as target, to weather modification work into
Row coordinates perfect planning type.
Urban ecological planning is with ecological and urban ecology principle for guidance, to realize the pass of city human and environment
For the purpose of the balance coordination of system, a kind of planning type of optimal urban environment is created for city dweller.
Urban construction is controlled using ratio of green space, afforestation coverage rate in existing urban green system planning.This is from certain journey
The ratio in greenery patches is controlled on degree, however but has ignored the different greenlands such as lawn, shrub and arbor with different size of ecology
Benefit cannot treat different things as the same.In order to improve greenery patches ecological functions, greenery patches intension is constrained, is advised it is proposed that being suitable for town and country ecology
The green capacity rate index system drawn, to guide urban ecological planning to pay attention to greenery patches ecological benefits, reasonable disposition Qiao's shrub group.
Green dose rate plan model be in green capacity rate index system to urban planning and construction land used outside, reflected with leaf area index
A kind of space planning method of the greenery patches ecological benefits as control Green Space Construction index.It calculates target by green quantity algorithm model
Total green amount of region status is covered in conjunction with the development & construction intensity of urban planning with the phytobiocoenose type and greening for planning selection
The characteristics such as rate calculate and plan green dose rate, thus to control the greenery patches community design of urban green space system ecological planning.
Leaf area index LAI (also referred to as green dose rate): total leaf area of unit area implants 1/2.The green amount of individual plants
Rate calculation formula:
Gv=4*Ga/ (π CD), wherein the total green amount of Ga--- planning construction, CD--- crown diameter
The green dose rate calculation formula in plot:
Gr=Ga/S, wherein the total green amount of Ga--- planning construction, S--- block area
It is exactly at present Singapore's Wang Wen gift about green dose rate project study representativeness to combine building floor area ratio and leaf area index
It is proposed green plot ratio.Refer to propose the conception of LAI value to target plot, target is reached by technological means and design method
LAI value, to accomplish energy saving, conservation of nature landscape and design the effect of intelligent building.The method more inquire into how
Reach higher green plot ratio by design, low-carbon environment-friendly allows people to enjoy green landscape.As in urban ecological planning
In, the green amount of status how is combined, the green dose rate in plot is scientifically planned as far as possible, green dose rate index system is established, to instruct city
Green space design not yet refers to.
