“…However, the driving mechanism of forest restoration is also limited by natural background conditions and influenced by photosynthetic utilization efficiency (Yan et al, 2019; Xiao et al, 2023; Li et al, 2022), such as the fragile karst geological background in southern China, which restricts the sustainability of large‐scale concentrated afforestation (Zhang, Brandt, Yue, et al, 2022). However, a large number of carbonate rocks and other soluble rocks are widely distributed in the karst area of South China Karst, making this area have significant karst carbon sink potential (Bai et al, 2023; Xiong et al, 2022). In addition, The impact of such activities on vegetation restoration changes has both direct and indirect effects (Dana et al, 2002).…”

Vegetation restoration in ecologically fragile areas has a significant carbon sequestration (CS) effect. However, it is usually difficult to achieve quantitative assessment at the regional scale for this part of human activity intervention. The Chinese government's ex‐situ poverty alleviation and relocation (EPAR) project has relocated approximately 10 million people from areas with a fragile ecological environment to urban centralized resettlement, which is a typical case of weakened environmental intervention by human activities (Guizhou Province accounting for approximately 20% of the total relocated population in China). The CS model of vegetation photosynthesis and spatial analysis of geographic information were used to quantify the contribution of human activities to the natural restoration of vegetation CS, based on the data of net primary productivity (NPP) of vegetation from 2000 to 2020. The results show that the implementation of the EPAR project acts as an external force to drive vegetation restoration and CS, which increases the slope of the carbon density change trend (from k = 30.9 to k = 57.41), resulting in an overall carbon density increase of 26.51 tCkm−2. The regional spatial analysis showed that the correlation coefficients between carbon density and relocation intensity in the 5‐year and 10‐year change were r = 0.976 (p < 0.01) and r = 0.949 (p < 0.05), respectively, indicating a significant positive correlation. Based on this, the CS contribution of vegetation in 84 districts in Guizhou Province that implemented EPAR projects was calculated, showing that 79 districts contributed positively, accounting for 94%. The average contribution of CS by vegetation restoration in each district was 0.0556 Tg, and offset CO2 emissions were 0.2059 Tg. The other five districts with a negative contribution to CS were distributed in regions with relatively stable ecosystems and mature forests. This shows that human intervention in the environment changes more significantly in fragile ecological areas.

“…The evolution of landscape pattern is a comprehensive reflection of the interaction and influence of natural elements and human factors in a certain region, as well as the different external characteristics and spatial combinations of various factors, which constantly affect the ecological process and marginal effect [13]. Exploring the evolution process of a landscape pattern is helpful for grasping the evolutionary characteristics and rules of the regional landscape, and to provide basic data for the assessment of the sensitivity, vulnerability and ecological risk of ecological degradation [14], which is the basis and important support for decision-makers to formulate reasonable and scientific urban planning [15]. At present, the analysis methods of landscape pattern evolution mainly include spatial statistical analysis, landscape index analysis and pattern dynamic model simulation [16,17].…”

Taking Yuxi City, a typical mountain-flatland in the southwestern karst mountainous area, as an example, we used six remote sensing images from 1995 to 2018 as the main data sources, and the grid scale was used to calculate the landscape pattern index in order to analyze the temporal-spatial evolution characteristics of the landscape pattern. The results are shown as follows: (1) At the class level, most landscape indices and fragmentation degrees of landscape units in the flatland area are significantly higher than those in the mountainous area. The layout of construction land and cultivated land is also more concentrated than that in the mountainous area, but the central tendency of forest and grass in the mountainous area is more eye-catching. (2) At the landscape level, although the landscape diversity index and landscape shape index of both the mountainous areas and the flatland areas decrease in the low-value area and increase in the high-value area, the proportion of high-value areas in the flatland area is noticeably greater. The proportion of the high-value areas of the largest patch index in the mountainous area is significantly greater, and in the flatland area, the low-value area continues to expand while the middle and high value areas continue to shrink. (3) The landscape shape of the flatland area is becoming more complex, and the landscape units in the mountainous area tend to be single. The natural landscape of forest and grass in the mountainous area continues to expand and tends to be contiguous, while the man-made landscape in the flatland area continually increases and shows fragmentation, reflecting the pattern characteristics formed by the coupling evolution of land use between two regions. The urban expansion and the increase in the construction land in the flatland area are mutually causal with the decrease in cultivated land and the increase in forest and grass in the mountainous area.

“…The fabrication of the SLM was inspired by a natural soil–microbe complex (Figure a). The soil ecosystem plays a key role in anthropogenic CO 2 sequestration, which can sink over one-third of the current yearly increase in atmospheric CO 2 . − Moreover, soil as a natural porous biomaterial provides various microenvironments for myriad microbiota to support their high diversity and density . The soil–microbe interfaces mediate various biogeochemical cycles and can modulate microbes in response to the external environment. − An artificial soil material was previously fabricated using a liquid-metal of gallium–indium (EGaIn), nanoclay, and starch for medical treatment, such as gut microbiome dysbiosis rectification and rodent colitis symptom alleviation .…”
