“…Digital elevation model (DEM) data with 30 m spatial resolution are derived from geospatial data cloud (http://www.gscloud.cn/ (accessed on 7 March 2021)). Although numerous types of topographic factors may impact ecological risk, based on the topography of Guangxi and results of previous studies, elevation and slope factors appear to considerably influence ecological risk in the region [36], prompting us to explore the effects of these factors on ecological risk in this work. We also incorporate additional data in our analysis, such as the leaf area index, gross domestic product (GDP), and population density data obtained from the Resource and Environment Science and Data Center of Chinese Academy of Sciences.…”

Due to ecological environmental fragility and soil erosion in Guangxi, studies of landscape patterns and associated ecological risks are needed to guide sustainable land development and ecologically sensitive land management. This study assesses dynamic spatial and temporal change patterns in land use and ecological risks based on 30 m land-use data, analyzes spatial correlations with ecological risks, and explores natural and socio-economic factor impacts on ecological risks. The results reveal: (1) A rapid and sizeable construction land increase in Guangxi from 2000 to 2018 associated mainly with loss of woodland and grassland. (2) Guangxi had the highest number of arable land patches from 2000 to 2018, and the distribution tended to be fragmented; moreover, the construction land gradually expanded outward from concentrated areas to form larger aggregates with increasing internal stability each year. (3) Guangxi ecological risk levels were low, low–medium, and medium, with significantly different spatial distributions observed for areas possessing different ecological risk levels. Regional ecological risk gradually decreased from the middle Guangxi regions to the surrounding areas and was positively correlated with spatial distribution. (4) Socio-economic factor impacts on ecological risk exceeded natural factor impacts. These results provide guidance toward achieving ecologically sensitive regional land-use management and ecological risk reduction and control, it can also provide a reference for ecological risk research in other similar regions in the world.

“…(Chen et al, 2021;Krzysztofik et al, 2020;Vojtek & Vojteková, 2016). Other previous studies also identified problems related to the relationship between humans and the environment using an ecological approach (Frankenberg et al, 2013;N & Nogueria, 2011;Yan et al, 2021). Thus, this research can be carried out using a spatial and ecological approach to mitigate disasters in mining areas, especially marble.…”

Indonesia has a karst region abundant in high-quality marble mining products but is also prone to disasters. Over the years, this area has experienced numerous natural disasters, thereby leading to the need for a land suitability assessment. This is a descriptive qualitative and quantitative research with data collected from field observations, laboratory tests, interviews, and documents. Four places in the center and adjacent areas of marble producers were selected for the research sample. The data collected were analyzed using the spatial and ecological approach, fishbone, tabulation, percentage, and SWOT analysis. The result showed that numerous land mismatches contribute to the occurrence of natural catastrophes, such as improper vegetation kinds, population settlement patterns, excessive exploitation, and unfriendly human activities. This study recommends a variety of measures to improve the mining area.

“…Human footprints or the impact of human activities on the ecology also occur more often in these areas. The transitional areas between cities and villages are also more prone to this situation, such as the agro-pastoral transition zone, urban-rural transition zone, and foothills [24,25]. This phenomenon can be seen in Figure 6, where the transitional area between the mountain and the plain in the southern area of Xi'an, distributed along the edge of the mountain, is a strip of a higher value of LERI regions that runs east-west.…”

“…In addition, landscape ecological risks are linked to the mining and development of road networks [22,23]. Areas with complex human activities also include interlacing zones, such as urban-rural interlacing zones and agro-pastoral interlacing zones, which are disturbed by multiple types of human activities and have a high value for landscape ecological risk research [24,25]. Human activities also indirectly affect global or regional ecological risks.…”

The increase in ecological risks caused by human activities has become a global concern in recent years. The Landscape Ecological Risk Index based on the theory of landscape ecology is more suitable for assessing large-scale ecological risks. Assessing landscape ecological risks and the mechanisms by which humans directly or indirectly affect them will help to manage and control the regions’ ecological risks through scientific and policy methods. In this study, a new model of landscape ecological risk assessment based on the moving window method is proposed. The Loess Plateau of China is used as an example, and the Human Footprint Index dataset of the Loess Plateau is constructed. Different human footprint factors and climate factors are applied, and the human direct and indirect effects on the landscape ecological risks of the Loess Plateau are explored based on the geographical detector model. The results show that, in 2000, 2010 and 2020, the landscape ecological risks of the Loess Plateau are currently in an unstable state, and the highest value area of the Landscape Ecological Risk Index continues to expand, with values of 113,566.1553 km2, 114,575.6772 km2 and 120,718.5363 km2, respectively. Among all the human footprint factors, the population density factor has the highest effect on the landscape ecological risks of the Loess Plateau. Among the climate factors, both the average temperature factor and the average lagged temperature factor have significant effects on the landscape ecological risks of the Loess Plateau. With the interaction of any two human footprint factors and climate factors, the effect of these factors on the landscape ecological risks of the Loess Plateau is enhanced.
