Abstract
Abstract. With the growth of urban population and the increasing urban density, urban green space has become a kind of precious and limited resources. It not only has a positive impact on the health of urban residents with high work-life pressure but also offers opportunities as part of blue-green solutions for sustainable urban water management. Therefore, to effectively utilise the limited green spaces, experts are exploring a way of organising the green space layout to balance human needs and other urban developing requirements (e.g., in this case, urban stormwater management) within the certain common area. With this target, translating the space accessibility to human and other urban developments on green space into space parameter is a critical step to organize space model for the multi-functional green space. Although there are plenty of existing spatial parameters developed for evaluating human accessibility (such as travel distance, land-use, spatial connectivity etc.), there isn’t a way to organize them to satisfy the diverse evaluation needs from different research purposes. Besides, most of them are suitable for analyzing space on a city scale or at least a precinct scale in a 2D model. To the accurate design on a micro-scale, it is still a big challenge. The reason is some parameters for city analysis don’t work on a micro-scale, and some parameters should be reorganised in the evaluation algorithm or should include more micro-scale factors. Thus, this paper, based on the characteristics of human behaviour, redefines the complex concept- accessibility and develop measurable parameters with feasible factors on micro-scale. Overall, this paper presents: (1) a new definition of walking accessibility of green space; (2) evaluation criteria (3) parameters (depth and Integration) reflecting connectivity criteria (4) Parameters (travel time and speed, slope, direction changes) relating travel distance criteria with updated evaluation algorithm and factors. This paper aims at useful spatial parameters and evaluation measures that are applicable to integrate human needs within multi-functional green space design, especially green stormwater management design.
Highlights
1.1 BackgroundThe academia has widely acknowledged that contacts with nature can benefit human health and well-being (Lee, Maheswaran, 2011, Harting et al, 2014)
The other one is, to the complex concept-space accessibility, while there are many spatial parameters provided for space analysis and design, they are mainly proposed from macro scale and focus on the transport planning, property price etc
Caring for human and sotrmwater management are the both key targets of sustainable urban development (United Nations Sustainable Development, 2020)).This research intends to develop the parameters of space accessibility based on the habit of human behaviour to support multifunctional stormwater management space design and improve the visiting experience
Summary
1.1 BackgroundThe academia has widely acknowledged that contacts with nature can benefit human health and well-being (Lee, Maheswaran, 2011, Harting et al, 2014). (Fletcher et al, 2015, Li et al, 2017) While they can effectively manage stormwater with green space, they occupy the green space without much consideration about the human daily needs. Green space researches of human health only care about how to organize the space layout, plant species and facilities for human needs without any consideration on the interaction with green water management. Regarding optimizing green space design on micro-scale (such as 1000X1000m or 500X500m), and cooperating with other professionals, there is still a research gap for developing the spatial parameters and measures for evaluating space accessibility of human. Caring for human and sotrmwater management are the both key targets of sustainable urban development (United Nations Sustainable Development, 2020)).This research intends to develop the parameters of space accessibility based on the habit of human behaviour to support multifunctional stormwater management space design and improve the visiting experience
