深圳市生态系统日常休憩服务供需关系及其变化趋势特征

Supply and demand of daily leisure services in Shenzhen urban ecosystem and its dynamic trend characteristics

城市化进程改变了自然生态格局,也破坏了生态系统服务功能。在城市区域内,生态系统文化服务与城市居民的身心健康息息相关,定量化地评估城市生态系统文化休憩服务的供需平衡及其空间特征可为城市土地利用规划与生态环境管理提供理论支撑。以深圳市为例,通过生态系统服务评估模型评估日常休憩服务的供给与需求,并对其空间匹配与动态变化趋势作出定量化计算。结果表明:深圳市日常休憩服务存在空间上的不匹配,日常休憩服务赤字区域共有338.03 km^(2),占市域面积的17.2%;日常休憩服务赤字面积呈扩大趋势,人均赤字面积大于10 m;的区域增加43.6%。深圳市需要在城市中心增加绿地空间,以满足城市居民的日常休憩需求。

The process of urbanization has changed the natural ecological pattern,thus destroying the ecosystem service function.In urban areas,ecosystem cultural services are closely related to the physical and mental health of urban residents,and quantitatively assessing the supply and demand balance of urban ecosystem cultural leisure services and their spatial characteristics can provide theoretical support for urban land use planning and ecological environment management.In this study,the supply and demand of daily leisure services were assessed by an ecosystem service assessment model in Shenzhen,and their spatial matching and dynamic trends were quantitatively calculated.The results show that there was a spatial mismatch of daily leisure services in Shenzhen,with a total deficit area of 338.03 square kilometers,accounting for 17.2% of the city area;the deficit area of daily leisure services was expanding,and the area with a deficit of more than 10 square meters per capita increased by 43.6%.Shenzhen needs to increase the green space in the city center to meet the daily leisure needs of urban residents.
