中文摘要 以深圳大学后海校区园林树木受台风山竹侵袭为研究案例,通过对树木风灾损伤和绿地环境的实地调查,结合台风风环境模拟,采用冗余分析研究城市绿地园林树木风灾损伤与相关影响因素的关系,采用变差分解定量分离不同类型影响因素的解释能力,确定关键因素。结果表明:1)树木自身抗风性、台风风速和绿地环境3类10个因素对树木风灾损伤均有影响,其中台风风速与树木风灾损伤的相关性最大,其次是树木自身抗风性、场地高程、是否有树池、干基周围是否有硬质铺装及覆盖度等。2)树木风灾损伤是众多因素综合作用的结果,而树木自身抗风性、台风风速和绿地环境这3类因素对树木风灾损伤的影响占总影响的65.1%,其中台风风速的影响大于树木自身抗风性,绿地环境的影响最小;树木自身抗风性与绿地环境的交互作用最大,台风风速与绿地环境的交互作用最小。最后,根据研究结果提出树木抗风对策,为城市绿地防风减灾规划设计与建设提供科学依据。

英文摘要 Rain shelters facilities are the public service facilities for coping with sudden rainfall. Their accessibility is one of the important factors to measure the space service efficiency. This paper selects the rain shelter facilities along the riverside green space in Xuhui, Shanghai, to investigate the public needs of rain shelter functions and the time cost threshold for their arriving at rain shelter facilities under different rainfall scenarios. The cost weighted distance method is used to evaluate the accessibility. The results show that:1) With the increase of rainfall, the public satisfaction of the accessibility to rain shelter facilities shows a downward trend, down from 44.04% in light rain scenario to 17.71% in heavy rain scenario, and the dissatisfaction increases from 11.29% in light rain scenario to 37.31% in heavy rain scenario; 2) The strip waterfront area in the southwest of Xuhui riverside is the area receiving the highest satisfaction in terms of the accessibility to the rain shelter, while the high-rise buildings and low green vegetation coverage areas in the northeast are the area with the highest dissatisfaction; and 3) The equidistant facilities and shortage of outdoor compound rain shelter facilities are the main reason for the low efficiency of rain shelters service in Xuhui's riverside area. At last, based on the scenario analysis, strategies for improving rain shelter facilities under different rainfall scenarios are proposed, in order to provide a reference for the functional improvement and precise configuration of rain shelter facilities in public spaces in the Yangtze River Delta.
