Ecological space is an important part of land space, a good ecological space is of great significance for sustainable development and human well-being. In the era of big data, POI (point of interest) data, as an important type of geospatial big data, can directly reflect the aggregation of various factors such as urban population density, development degree and intensity. Based on the POI data of Zhengzhou in 2007 and 2017, using the spatial analysis tool of ArcGIS software, the POI data classification information of Zhengzhou city is extracted. The grid analysis method and quadrat proportion method are used to identify the urban ecological space, and the urban ecological spatial pattern of Zhengzhou city is analyzed from the perspective of sustainable development. It is found that with the improvement of urbanization and infrastructure, the distribution of green space in Zhengzhou is more balanced, the allocation of green space resources is more reasonable, and the urban living space is more equitable. Using POI data to identify urban ecological space and analyze spatio-temporal evolution can make urban land spatial planning more scientific and practical.
