“…Our study further corroborates the influence of establishing ecological function areas on land fluctuations and land use and cover changes, in line with previous research findings [45]. Both land fluctuations and land use and cover changes are fundamentally driven by human activities and naturally exhibit spatial aggregation effects.…”

“…In response to this, China has initiated national ecological function assessments and status surveys since the early 21st century and introduced the concept of national ecological function zoning in 2008. The zoning process involves delineating function areas covering a total of 2,336,700 km 2 , which accounts for 24.34% of China's total land area [45]. These key ecological function zones are further classified into six distinct groups based on their dominant functions (Figure 1).…”

The establishment of nature reserves and ecological function areas is crucial for preserving the natural environment and the invaluable services provided by ecosystems. In our study, we conducted a comprehensive analysis using the 2011–2020 Chinese land cover dataset to examine the impact of ecological function areas on regional land use and cover change. This analysis allowed us to quantify and visualize the intensity, aggregation effects, and transformation paths of land cover change while considering China’s ecological function areas. Our findings highlight notable disparities in land cover types between the ecological function area and its surroundings. Within the ecological function area, forest and grassland dominate, constituting 67% of the total land cover. In contrast, outside the ecological function area, there is a greater presence of wasteland, in addition to forest and grassland. Moreover, the abundance of impervious surfaces, which are closely linked to human activities, is significantly higher outside the ecological function area, almost double the amount found inside. By examining specific land cover types, we observed that forests exhibit the least change within the ecological function area, whereas croplands experience the least change outside. Throughout the study period, approximately 8.1% of land cover pixels underwent changes, with some areas displaying a frequency of change reaching up to 2. Interestingly, the number of high-frequency land use and cover change pixels inside the ecological function area is only half of the outside. Notably, a higher percentage of impervious surfaces within the ecological function area (0.13%) were converted into cropland compared to the outside (0.07%). Understanding the dynamics of land cover change within China’s ecological function areas provides valuable insights for effective land resource management and planning. It enables us to make informed decisions to ensure the sustainable development and conservation of these areas.

As an important resource for human survival and development, the utilization efficiency of cultivated land is directly related to national food security and social harmony and stability. Based on the stochastic frontier production function, this paper estimated the cultivated land use efficiency of 342 prefecture-level administrative regions in China from 2003 to 2019 and used spatial autocorrelation analysis and the Gini coefficient decomposition model to explore the spatial agglomeration and spatial disequilibrium of cultivated land use efficiency in China. The results showed the following: (1) Overall, the efficiency of cultivated land use in China has steadily improved since 2003, but the overall level remains low. The use efficiency of cultivated land decreases in the order of eastern, northeastern, western, and central regions, and the use efficiency of cultivated land in the central region increased the fastest. (2) From the perspective of the spatial dimension, the cultivated land use efficiency in urban areas of China has a multi-core structure of “high in the south and low in the north, high in the east and low in the west” and an obvious spatial differentiation pattern. At the same time, the spatial aggregation characteristics of cultivated land use efficiency have become more prominent with the passage of time. (3) There are obvious regional differences in cultivated land use efficiency in China, showing a downward trend as a whole, and the gap between regions is the main source of spatial non-equilibrium, followed by the super-variable density and the gap within regions. Revealing the temporal and spatial changes in cultivated land use efficiency is helpful to understand the present situation of cultivated land use and to formulating effective land use policies.

Monitoring land cover changes in protected areas is crucial to control the conservation efficiency of biodiversity and natural ecosystem conditions, especially in Ecuador, one of the most megadiverse countries in the world. Therefore, the purpose of the present study has been to estimate spatiotemporal changes in the landscape and the level of fragmentation using remote sensing in Llanganates National Park (PNL), a protected area in central Andean Ecuador. To obtain land cover, satellite images were processed using the Maximum Likelihood Classification (MLC) algorithm. After statistical analysis, it was encountered that there is no significant difference in land cover change between the years 1991 to 2016 nor among the three watersheds, while the level of fragmentation in the PNL is low. Land cover changes in the study area are not evident, as it is a protected area where ecosystems are usually expected to maintain their initial conditions over time. Therefore, with these results it has been concluded that the biodiversity and landscape conservation processes in the PNL are effective.
