The scientific siting of urban parks is critical for sustainable urban environment development, and this study aimed to identify suitable areas for future urban parks in Nanjing, China. This study has integrated geographic information systems (GIS) and fuzzy hierarchical analysis (F-AHP) in order to evaluate the suitability of the site selection of urban parks in Nanjing, China. Different physical, natural, environmental, accessibility, and human activity factors were evaluated in order to assess the suitability of a park site. The results revealed that 5% were highly suitable for urban park site selection, 36% were more suitable, 32% were moderately suitable, 19% were less suitable, and 8% were unsuitable for urban park site selection. The findings suggest that the areas that are highly suitable for urban park placement are located in the western and eastern parts of Nanjing. Carbon storage was the most important factor in the suitability of urban park site selection, followed by the normalized difference vegetation index (NDVI) and the heat-island effect. The methodology that has been adopted in this study helps to improve the methodological framework of combining F-AHP and GIS; in addition, generating urban park site selection maps assists planners and decision-makers in making scientific site selection decisions.

“…It is situated at the intersection of two highly urbanized urban zones along the river and the coast of China (Figure 1). One of China's most economically active, urbanized, and population-absorbing areas, the Yangtze River Delta will contribute 24% of the nation's population and gross domestic product in 2021 (Qiao et al, 2021). (Yu et al, 2022).…”

Land pressure evaluation in the Yangtze River Delta region: A perspective from production-living-ecology

Chen

et al. 2023

Preprint

The limited land is under unprecedented pressure from production, living and ecology. In order to evaluate the land pressure in the Yangtze River Delta region in 1995, 2000, 2005, 2010, 2015, and 2020 from the perspective of production, living, and ecology. This study builds a land pressure evaluation index system based on a fuzzy comprehensive evaluation model using multi-source and multi-scale data. In order to investigate trade-offs and synergies among production, living, and ecology pressures, we use the mechanical equilibrium model in physics. We then analyze land pressure model reliability and uncertainty using Monte Carlo simulations. The results show that (1) Our model can effectively reveal the level of land pressure and reflect the land pressure geographical pattern of “high in the east and low in the west, high in the south and low in the north” that characterizes the Yangtze River Delta region. (2) While living and ecology pressures are tending to rise, production pressures are tending to decrease. (3) Except for Shanghai, the trade-off areas are primarily concentrated in economically successful regions with high production and living pressure and low ecology pressure. The coordinated areas are primarily found in northern Jiangsu Province and northern Anhui Province.

“…The YRDR occupies around 3.57 Â 10 5 km 2 , accounting for approximately 3.7% of China's total area, and its resident population is expected to reach over 230 million by 2021, accounting for 16.74% of China's total population. One of China's most economically active, urbanized, and population-absorbing areas, the YRDR will contribute 24% of the nation's population and gross domestic product in 2021 (Qiao et al, 2021). The built-up land area in the YRDR was 4.84 Â 10 4 km 2 in 2020, with an annual increase rate of roughly 751.75 km 2 from 1995 to 2020.…”
