| Abstract: |
| "Greening Design with Water" is the way of ecological
wisdom to alleviate the contradiction between the continuous
improvement of the construction scale and quality of urban green
space in Northwest China and the limited water resources. Based
on 16 ecological background and vegetation types belonging to
62 prefecture-level cities in Northwest China, three types of plant
landscape zoning and types of zonal urban green space which can
be used as reference in planting design are proposed, as well as the
strategies of evaluating the water quantity condition, using water saving irrigation, and using site design strategy to improve and
optimize the water quantity and water distribution condition of the
site. This paper also expounds the basic design mode of determining
green by water from three aspects: the calculation of water supply
and demand balance, the division of catchment unit and green space
layout, and the design mode of ground cover plant community under
water-saving demand. Taking the green space ecological design
practice of a small town in Qinghai Province as an example, this
paper further explains the ecological design process of "Greening
Design with Water". |
