Quality Evaluation of Park Green Space Based on Multi-Source Spatial Data in Shenyang

Abstract

Park green spaces serve as essential urban public recreation spaces and represent significant components of urban construction land. Investigating the quality of park green spaces is a vital requirement for the establishment of a high-quality urban living environment and the enhancement of land use efficiency. This study developed a quality evaluation index system for park green spaces in Shenyang, considering the constituent elements of recreational spaces. By categorizing 168 park spaces into four size grades and employing the entropy-TOPSIS method with multiple data sources, the research assessed and analyzed the generally quality of park green spaces in Shenyang. Additionally, the study analyzed factors limiting park green spaces and introduced the Recreational Quality Index (RQI) to represent the distribution of park green space resources within the study area. The results demonstrated that 46 low-quality park green spaces require urgent improvement, and the riverside area and the vicinity of the second ring road possess high-quality park green space resources. Barriers of the same scale in park green spaces exhibited similar characteristics. Park green spaces in Huanggu District were allocated recreational resources optimally. The analysis determined that system construction and deep cultural heritage are crucial factors. This study can offer a scientific basis and recommendations for the development of park green spaces and the enhancement of efficient urban land use.

Evaluating the Spatial Quality of Urban Living Streets: A Case Study of Hengyang City in Central South China

“…Based on the value of the interval, they are categorized as high quality, medium-high quality, medium quality, medium-low quality, and low quality. Figure 2b illustrates the results of a kernel density analysis performed on the QOLSS results to analyze the distribution characteristics of various qualities [42,43]. The proportion of each quality type is summarized in Figure 3.…”

Examining Spatial Inequalities in Public Green Space Accessibility: A Focus on Disadvantaged Groups in England

“…National green space indicators differ significantly between cultures [17][18][19][20][21][22]. For instance, the European Environment Agency (EEA) recommends that residents should have access to a green space within a one-kilometre radius, equivalent to approximately a 15 min walk [23].…”

“…Firstly, previous studies have primarily focused on comparing PGS inequalities between vulnerable and nonvulnerable groups, neglecting a more in-depth examination of the specific variations within vulnerable groups, particularly concerning the interactions between different vulnerability factors. Existing research has focused on which factors influence inequalities in public green space [12][13][14][15]18,19], but how each socioeconomic variable of disadvantaged groups is influenced by the allocation of green space is not considered in most studies. Comparing different socioeconomic variables of deprivation can understand which disadvantaged groups face the most serious green space inequality, further promoting environmental justice.…”
