Abstract:With the improvement of urbanization level and urbanization process, the urban ecosystem has gradually become fragile. Enhancing the level of urban ecological resilience plays a key role in urban development. Based on the core connotation of resilience, evaluating the level of urban ecological resilience, exploring the spatial differences of urban ability to prevent and resolve ecological risks, and formulating regional ecological governance system are effective ways to improve urban ability to prevent and resolve ecological risks. In this study, we constructed the spatial evaluation model of urban ecological resilience level from three aspects of resistance, adaptability and recovery. We took the data of administrative boundary, land use, key pollutant discharge units, and the population of Tongzhou District in Beijing in 2020 as an example. This paper evaluated the spatial pattern of ecological resilience in Tongzhou District in 2020, and then used the spatial autocorrelation model to study its regional ecological governance. Finally, the driving force was analyzed by using geographic weighted regression (GWR) model to explore the impact of socio-economic level on the horizontal space of urban ecological resilience, and put forward suggestions. The results showed that:(1) in terms of spatial structure, the low value areas of ecological toughness were the most, accounting for 52.80%, mainly distributed in the north, northeast, west-central and southeast areas of Tongzhou District. The high value areas were the least, accounting for 0.83%, which scattered in the western and southern regions. Due to the lack of relatively appropriate overall planning and overall arrangement in Tongzhou District, the circulation system of urban ecosystem has been negatively affected, resulting in weak resistance in southeast China. At the same time, in recent years, the southward movement of precipitation points has led to the loss of a large number of water resources under the action of urban heat island effect, and the resilience in the southeast of Tongzhou District and along the Tongzhou Grand Canal in Beijing presented a wide range of low value levels. (2) The northwest of the center of Tongzhou District is Beijing Municipal Administrative Center, showing the concentration and distribution of low toughness level-high pollutant discharge enterprise density. The low value areas of ecological toughness were mainly concentrated in Xinhua Street, Zhongcang Street, Yuqiao Street and other areas. These indicated that such areas had relatively low ability to prevent and resolve environmental ecological risks, and it is necessary to make sustainable regionally ecological governance for the ecological crisis according to local conditions as well as enhance the regional ability to adjust ecological risks. (3) Combined with the driving force analysis of GWR Model, the level of urban ecological resilience was mainly driven by urban functional diversity. The stronger the urban functional diversity, the lower the level of urban ecological resilience. The negative impact was most significant in the Beijing Municipal Administrative Center. The research results provide a theoretical basis for the development and optimization of urban ecological resilience level, which will play a positive role in promoting the rational utilization and effective protection of land and space.
