“…Combined with Figure 3 and our field investigation, most areas with low RSEI values were in the southern area, where the petrochemical (i.e., high-level hemeroby areas) is distributed widely. It can be further speculated that the development of the traditional petrochemical industry has led to the pollution and deterioration of ecological land, which also verifies the previous findings [58,82,87,88].…”

Human transformation of the landscape is reflected in its composition and spatial pattern. Therefore, exploring the response of the eco-environment to the composition and spatial pattern of the landscape is beneficial to providing a theoretical basis for urban planners. In this study, we take a typical oil city in China as an example and introduce the hemeroby index, landscape metrics, and a remote sensing-based ecological index (RSEI) to calculate and evaluate the urban landscape pattern, human disturbance, and eco-environmental quality, as well as exploring the relationships between them. The results demonstrate that the mean RSEI value of the study area was 0.4866, indicating that its eco-environmental quality was relatively moderate. The whole study area had a relatively high degree of human disturbance (hemeroby index = 7.4498), where the effect of human disturbance on the eco-environment was more intense in natural ecosystems, such as forest and grasslands, but less intense in artificial landscapes, such as built-up areas and farmlands. The urban landscape pattern was significantly correlated with eco-environmental quality, among which the proportion of green space and impervious surface had the strongest correlations with the mean RSEI, with correlation coefficients of 0.538 and −0.577, respectively. In addition, the correlation between the landscape pattern and the RSEI presented obvious spatial heterogeneity.

“…Most scholars have focused on the value of cultivated land resources in rural areas [19,24,28], while only a few have studied them in metropolitan areas to analyse spatial distribution patterns and influencing factors [11,28,40]. Su [30] assessed the cultivated land resources in Keshan County, Heilongjiang Province, and found that the economic, social, and ecological values of the cropland were 38.01, 107.53, and 13.5 thousand yuan/hm 2 , respectively, and the comprehensive value was 146.89 yuan/m 2 ; moreover, the economic and ecological value of the cropland presented decreasing values.…”

“…The comprehensive value accounting for cultivated land has originated from the System of Environmental-Economic Accounting (SEEA) in the United States, and several foreign scholars have subsequently studied the economic value of its resources using the production function, land market, and shadow value methods [1,7]. The gradual enrichment of theory and practice in the United States has prompted scholars to focus on various economic models to estimate the asset value of cultivated land, such as the hedonic pricing and crop yield models [8][9][10][11]. In Europe, scholars have adopted a more integrated approach, which has focused on understanding the environmental benefits of agriculture and developed sustainable land use policies which integrate socioeconomic, ecological, and political factors [3,12].…”

Accounting for the Logic and Spatiotemporal Evolution of the Comprehensive Value of Cultivated Land around Big Cities: Empirical Evidence Based on 35 Counties in the Hefei Metropolitan Area

Exploring the value of cultivated land resources around big cities is an important prerequisite for when realizing the “trinity” of cultivated land protection in terms of quantity, quality, and ecology. At present, the value of cultivated land resources faces the problem of having a low comparative efficiency of economic output, inadequate visualisation of asset value, and serious undervaluation. The manifestation of social, ecological, and cultural values in cultivated land plays an important role in accurately calculating the value of cultivated land. Therefore, this study attempted to clarify the composition and account for the logic of the comprehensive value of cultivated land around big cities. Taking the Hefei metropolitan area as an example, we used mathematical modeling and geostatistical analysis to measure the integrated value of cultivated land around big cities from 2010 to 2020 and analyse the spatial and temporal evolution characteristics and influencing factors. The results revealed a 2:7:1 ratio of economic, social, ecological, and cultural values for cultivated land in the metropolitan area. The comprehensive value of cultivated land was higher in 2020 than in 2010, was approximately 7.7 times the current compensation standard, and was significantly affected by the natural geography, economic development, cultivated land conditions, and protection policies. Furthermore, the comprehensive value showed spatial differentiation characteristics of ‘high in the east and south and low in the west and north’, and a spatial agglomeration effect was evident in some areas. A significant increase was observed in the social value of cultivated land, followed by an increase in the ecological and cultural values, whereas a slow downward trend was observed for the economic value. The economic value of cultivated land around big cities showed a downward trend, whereas the social, ecological, and cultural values showed upward trends. In the future, differentiated policy tools should be adopted based on the spatial heterogeneity of the comprehensive value of cultivated land in the Hefei metropolitan area to enhance their comprehensive value. In addition, scientific and reasonable compensation standards should be established, and high-quality agricultural development with the high-level protection of cultivated land should be promoted in metropolitan areas.

“…In urban areas, the urban heat island effect (UHI) is remarkable [1][2][3][4]; it is caused by the low reflectance of the materials used in cities and the scarcity of vegetation and evapotranspiration with consequences such as an increase in ambient temperature between 4-5 • C in urban centers compared to the periphery, which implies an increase of 5-10% in the demand for cooling, the impoverishment of air and water quality and the deterioration of people's health. [5,6].…”

This work focuses on the protection of measurement sensors against accidents, vandalism, or theft and on the improvement of the data collected due to the interference produced by these protections. These sensors are part of a larger study, within the framework of a LIFE Heatland project, carried out in a Spanish city, Murcia, with the fundamental objective of minimizing the urban heat island effect using pavements with lower solar energy storage than traditional ones. The study presented here has been carried out through the implementation of aluminum tubes that protect the sensors installed in the street. Once the problem of sensor protection had been solved, the problem of thermal interference in the measurements due to overheating inside the tubes had to be overcome by means of discriminated dimensionless analysis techniques, focusing on heat transfer by convection of the air flow in the inner part of the tube, by finding the most suitable size and materials to complement the outer aluminum coating. In particular, the search for the critical radius of the tubes was essential since it allowed the insulator size to be optimized. Derived from the study carried out to avoid the overheating of the tube, a small part was covered with a dark material and holes were made to improve air circulation inside the tube, allowing adequate measurement results to be obtained. Finally, the results showed that the designed device was suitable for temperature measurement, since small variations were observed with respect to the control device.
