郊野绿道生物多样性的公众感知——以杭州青山湖绿道为例

Public Perception of Biodiversity along Countryside Greenways:A Case Study of Qingshan Lake Greenway in Hangzhou

以杭州青山湖绿道为例,对绿道进行区段划分,在各区段进行生物多样性评价,并采用现场问卷、个别访谈的形式对公众的生物多样性感知情况进行调查。结果表明:公众对生物多样性的满意度与整体游览满意度呈现正相关;公众具备较为准确感知生物多样性水平的能力,对植被结构复杂、亲水性较好区域的生物多样性评价较高;低学历受访者对生物多样性的满意度高于高学历受访者;多次到访和停留时间较长的受访者对生物多样性的满意度较高。基于此,提出构建层次丰富的植被结构、重视亲水空间营造、结合生物多样性科普设计景观设施、合理规划人工景观所占比例等郊野绿道规划设计优化策略,以期为平衡生物多样性保护与公众游憩提供科学指导。

Studying the publics perception of biodiversity is of great significance for optimizing the planning and design of rural greenways and the conservation of urban and rural biodiversity.With Hangzhou Qingshan Lake Greenway for a case study,this paper divides the greenway into sections,conducts biodiversity assessment in each section,and investigates the public perception of biodiversity using questionnaire survey and individual interviews.The results show that the public satisfaction with biodiversity is positively correlated with overall visitor satisfaction.The public has the ability to accurately perceive the level of biodiversity,and gives a higher evaluation of biodiversity in the areas with complex vegetation structure and good hydrophilicity.Respondents with low education are more satisfied with biodiversity than respondents with high education,and higher satisfaction with biodiversity is observed among respondents who make multiple visits and longer stay.Based on these findings,strategies are put forward to provide scientific guidance for balancing the relationship between biodiversity conservation and public recreation,such as construction of a rich vegetation structure,emphasis on hydrophilic space creation,and landscape facilities design in combination with biodiversity science.
