Analyzing the Land Use and Cover Change Inside and Outside China’s Ecological Function Area

Abstract

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.

Analyzing Farmers’ Engagement with Sustainable Agricultural Policies: Insights from Indonesia’s LP2B Initiatives

“…This widespread problem affects an estimated 1.5 billion people and encompasses a quarter of the total land area in all agroecological zones worldwide [15]. Annually, approximately 5 to 8 million hectares of previously productive land fall out of global cultivation due to degradation [16]. Therefore, emphasizing the critical importance of sustainable land use and soil protection is crucial not only for agricultural productivity, but also for addressing broader concerns related to food security, climate resilience, and human well-being [17].…”
