“…The agro-pastoral transitional zone in northern China is an important zone for agricultural production and an important area for protecting China's food security. It serves as a crucial transition area between traditional pastoral and agricultural ecosystems, functioning as a valuable environmental safety buffer [20,21]. It represents the transition zone from the semi-humid agricultural region to the arid and semi-arid pastoral region.…”

The agro-pastoral transitional zone in northern China is an important agricultural and pastoral production base. This study focuses on the eastern section of the agro-pastoral transitional zone in northern China. Combined with spatio-temporal analysis, stepwise regression, and gray relation analysis, we analyzed the average annual growth rate, spatio-temporal changes, and influencing factors of agricultural and pastoral production in the study area during 2000–2020. The results show that, in the past 20 years, the agricultural and pastoral production of the 50 municipal districts and counties has significantly changed, among which the agricultural production of 38 municipal districts and counties has shown an extremely significant increase. Generally, the growth rate of agricultural production is higher than that of pastoral production. Agricultural and pastoral production in the study area is influenced by socio-economic and land use/cover factors, with an average correlation degree of 0.79 and 0.88, respectively. Climate change affects agricultural production in agricultural counties, with a correlation degree of 0.85. The results of this research provide valuable insights into understanding the long-term temporal and spatial changes in agricultural and pastoral production and help to develop sound agriculture and pastoral management practices in the eastern section of the agro-pastoral transitional zone in Northern China.

“…However, because of the long-term lack of extensive observation data on abandonment and reclamation, the widely used land cover datasets basically do not contain the classification of abandoned or reclaimed land, which has led to fewer studies on the spatiotemporal patterns and extent of abandonment and reclamation in the northern farming-pastoral zone [10,11]. Furthermore, many Chinese researchers who rely on remote sensing technologies often evaluate cropland changes at discrete time points, instead of monitoring changes over a continuous period due to dataset update limitations that do not align with typical crop rotations [12,13]. Some studies use the annual change detection method to explore cropland abandonment or land reclamation [5,14].…”

The farming–pastoral zone in northern China is one of the most ecologically sensitive areas globally, having experienced extensive cropland abandonment and land reclamation over decades, primarily influenced by policy adjustment and global warming. However, the spatiotemporal patterns and suitability of long-term cropland change remain poorly understood. Using the annual China land cover dataset (CLCD), we provide a cropland abandonment and land reclamation mapping approach based on actual land use processes (rather than land cover conditions) to investigate spatiotemporal features of abandonment and reclamation and evaluate the rationality. Our findings show that: (1) Returning farmland to forest and grassland has been a clear trend in the study area over the past 30 years. Specifically, cropland use has undergone three phases of change, i.e., cropland contraction and expansion alternately (before 2000), followed by substantial abandonment (after 2000), and low-intensity reclamation (after 2010). (2) In the last decade, the intensity of the abandonment of cropland with high and moderate suitability is low. The rate of abandonment decreased, while the intensity of land reclamation was relatively high. The rate of the reclamation increased, and the spatial distribution of cropland tended to be reasonable. Our study emphasizes the importance of monitoring actual cropland changes based on land use processes, and this method can be effectively extended to regional or global long-term cropland monitoring.

“…Liu et al [ 22 ] showed that grassland, cropland, and forest land were the main types of land use in the northern agro-pastoral ecotone, and the total area was more than 4.30 × 10 5 km 2 , accounting for more than 91.83% and the transfer area between grassland and cultivated land was as much as 1.67 × 10 4 km 2 . In addition, as a sensitive zone of global climate change, the agro-pastoral ecotone is the most concentrated and obvious area of environmental problems [ 23 ]. A more prominent one is the contradiction of water use.…”

Improving plant water use efficiency is a key strategy for the utilization of regional limited water resources as well as the sustainable development of agriculture industry. To investigate the effects of different land use types on plant water use efficiency and their mechanisms, a randomized block experiment was designed in the agro-pastoral ecotone of northern China during 2020–2021. The differences in dry matter accumulation, evapotranspiration, soil physical and chemical properties, soil water storage and water use efficiency and their relationships among cropland, natural grassland and artificial grassland were studied. The results show that: In 2020, the dry matter accumulation and water use efficiency of cropland were significantly higher than those of artificial and natural grassland. In 2021, dry matter accumulation and water use efficiency of artificial grassland increased significantly from 364.79 g·m−2 and 24.92 kg·ha−1·mm−1 to 1037.14 g·m−2 and 50.82 kg·ha−1·mm−1, respectively, which were significantly higher than cropland and natural grassland. The evapotranspiration of three land use types showed an increasing trend in two years. The main reason affecting the difference of water use efficiency was that land use type affected soil moisture and soil nutrients, and then changed the dry matter accumulation and evapotranspiration of plants. During the study period, the water use efficiency of artificial grassland was higher in years with less precipitation. Therefore, expanding the planted area of artificial grassland may be one of the effective ways to promote the full utilization of regional water resources.
