城市治理与绿地空间——新型城镇化背景下土地使用方式的转型

Urban Governance and Green Space——The Transformation of Land Use during New-style Urbanization

城市绿地空间既有助于调节城市生态环境,也可以改善居民的生理和心理健康、促进社会整合,在城市人文生态系统中具有重要作用。以绿地空间为切入点,探讨不同发展阶段下,城市治理思路对土地空间使用方式的影响。基于中国336个城市数据进行研究,结果显示,城市经济发展水平越高,绿地空间的面积和占比越大。同时,经济发展水平和城乡差距存在交互作用,在经济发展水平较低、城乡差距较大时,城市治理目标以经济导向为主,相当程度上忽视了空间使用的社会生态效益,绿地面积较小;在经济发展水平较高、城乡差距较小时,城市治理呈现多元化价值导向,强调空间使用的综合效益,绿地面积提高。研究结果从侧面论证了同时实现社会经济发展和环境友好的可能性。

Green space not only improves urban ecological environment, but also increases the physical and psychological wellbeing of urban residents and advances social integration, thus playing an important role in urban humanistic and natural ecosystems. Based on the study of green space, the effect of urban governance on land use was discussed in the paper. An empirical study based on data from 336 cities in China shows that economic development is positively associated with both the area and ratio of green space.Additionally, there is an interaction effect between economic development and rural-urban gap. In cities with lower levels of economic development and a bigger rural-urban gap, urban governance is more economy-oriented and emphasizes less on the socioecological benefits associated with land use, resulting in less green space;in cities with higher levels of economic development and a smaller rural-urban gap, urban governance stresses multidimensional development and the economic, social, and ecological benefits of land use, hence there is more green space. The results illustrate the influence of urban development on land use, and imply the possibility of a win-win situation for socioeconomic development and environmental protection under the guidance of green development strategy, which is crucial for urban green development.
