Abstract
Urban public open spaces refer to open space between architectural structures in a city or urban agglomeration that is open for urban residents to conduct public exchanges and hold various activities. Sustainable Development Goal (SDG) 11.7 in the 2030 UN Agenda for Sustainable Development clearly states that the distribution characteristics of public open spaces are important indicators to measure the sustainable development of urban ecological society. In 2018, in order to implement the sustainable development agenda, China offered the example of Deqing to the world. Therefore, taking Deqing as an example, this paper uses geographic statistics and spatial analysis methods to quantitatively evaluate and visualize public open spaces in the built area in 2016 and analyzes the spatial pattern and relationship of the population. The results show that the public open spaces in the built-up area of Deqing have typical global and local spatial autocorrelation. The spatial pattern shows obvious differences in different parts of the built area and attributes of public open spaces. According to the results of correlation analysis, it can be seen that the decentralized characteristics of public open spaces have a significant relationship with the population agglomeration, and this correlation is also related to the types of public open spaces. The assessment results by SDG 11.7.1 indicate that the public open spaces in the built-up area of Deqing conform to the living needs of residents on the whole and have a humanized space design and good accessibility. However, the per capita public open spaces of towns and villages outside the built area are relatively low, and there is an imbalance in public open spaces. Therefore, more attention should be paid to constructing urban public open spaces fairly.
Highlights
In 2015, the UN Development Summit approved and adopted the 2030 Agenda for Sustainable Development, which sets out 17 Sustainable Development Goals (SDGs) covering three major areas, economic, social, and environmental, charting a course for the development of countries and international cooperation
Combining SDG 11.7 with the actual situation of Deqing, and considering the availability and quantitative characteristics of the data, this paper focuses on urban built-up areas, analyzes the average proportion of public open spaces used by all, and provides a guarantee for the construction of urban public open spaces that can meet everyone’s needs
Some scholars used the spatial autocorrelation analysis in the field of river network monitoring [21], spatial variations analysis of NPP [22], and agricultural spatial relationship analysis of drought propagation [23]. According to these kinds of research results, we found that geographic information system (GIS) spatial analysis methods can help us to identify the spatial pattern among kinds of urban objects, but most of their research only used the local indicators of spatial association (LISA) to judge the relationship between these events in urban environment, and lacked a quantitative description of the causes of these events
Summary
In 2015, the UN Development Summit approved and adopted the 2030 Agenda for Sustainable Development, which sets out 17 Sustainable Development Goals (SDGs) covering three major areas, economic, social, and environmental, charting a course for the development of countries and international cooperation. Based on the SDG global indicator framework and geographic statistical information, the project team carried out a localized evaluation and analysis of the implementation of Deqing County, combining quantitative, qualitative, and localization data [1,2], and offered the Deqing sample to the international community. In Deqing, the aspects of inclusivity, sustainability, and disaster resistance comprehensively reflect the county’s progress in the practice of creating a sustainable city and human settlements. The aim of SDG 11 is to analyze the proportion of public spaces per capita to reflect livable environmental conditions. Combining SDG 11.7 with the actual situation of Deqing, and considering the availability and quantitative characteristics of the data, this paper focuses on urban built-up areas, analyzes the average proportion of public open spaces used by all, and provides a guarantee for the construction of urban public open spaces that can meet everyone’s needs
