“…The functional relationships of cropland are not mutually exclusive; cooperative (synergistic) and trade-off (balanced) relationships exist [14,15]. For example, the long-term excessive application of pesticides, fertilizers and other products may lead to a decline in farmland productivity [16,17]. Therefore, an efficient evaluation of the multifunctional capacity of cropland resources and the clarification of the synergistic and balanced relationships are crucial for the sustainable utilization of cropland resources [18].…”

Cropland is a comprehensive system influenced by the natural environment and human activities. This article collects the data of cropland use, soil, and other geographic, social and economic factors in the study area and then uses the methods of system analysis, induction and deduction to propose a new research perspective for establishing a cognitive framework and analyzing cropland resources and their functions. The framework is used to assess the rapidly urbanizing region of Guangzhou and investigate the production, ecological, and living functions provided by cropland resources. Synergistic relationships between functions are analyzed using the hot and cold spot methods. The results indicate that the production function of cropland resources in Guangzhou is good, the ecological function is favorable, and the living function is relatively low. A synergistic relationship between the three functions is observed in 91% of areas of Guangzhou, whereas a balanced relationship occurs in some areas of the southern part of Zengcheng, the northwestern and northeastern parts of Conghua, and the western part of Nansha. This research provides guidance for managing cropland resources and ensuring their sustainable utilization.

“…This area belongs to the continental semiarid monsoon climate and is in the temperate zone, with a mean annual temperature of 3–7°C and a mean annual rainfall (AP) of 350–500 mm ( Huang et al., 2022 ). In recent years, many ecological problems have been caused by rapid population growth and increased demand for land, food, housing, and employment ( Kooch et al., 2022 ), especially the decline of the groundwater level ( Maihemuti et al., 2021 ). At the same time, the aggravation in evapotranspiration would be more evident than rainfall with climate warming in the future, which would result in more drought and impulse the aridification of this area ( Dai and Zhao, 2017 ; Su et al., 2018 ).…”

IntroductionUnderstanding the impact of deep groundwater depth on vegetation communities and soil in sand dunes with different underground water tables is essential for ecological restoration and the conservation of groundwater. Furthermore, this understanding is critical for determining the threshold value of groundwater depth that ensures the survival of vegetation.MethodThis paper was conducted in a semi-arid region in eastern China, and the effects of deep groundwater depth (6.25 m, 10.61 m, and 15.26 m) on vegetation communities and soil properties (0–200 cm) across three dune types (mobile, semi-fixed, and fixed dunes) were evaluated in a sand ecosystem in the Horqin Sandy Land.ResultsFor vegetation community, variations in the same species are more significant at different groundwater depths. For soil properties, groundwater depth negatively influences soil moisture, total carbon, total nitrogen, available nitrogen, available phosphorus concentrations, and soil pH. Besides, groundwater depth also significantly affected organic carbon and available potassium concentrations. In addition, herb species were mainly distributed in areas with lower groundwater depth, yet arbor and shrub species were sparsely distributed in places with deeper groundwater depth.DiscussionAs arbor and shrub species are key drivers of ecosystem sustainability, the adaptation of these dominant species to increasing groundwater depth may alleviate the negative effects of increasing groundwater depth; however, restrictions on this adaptation were exceeded at deeper groundwater depth.

“…The geomorphological features of the region are characterized by alternating sand dunes and slightly undulating lowlands ( Luo et al, 2020 ). In recent years, expedited population growth and the resulting boosted requirement for food, housing, employment, and land have led to more ecological problems ( Kooch et al, 2022 ), especially the decline of the ground water level ( Maihemuti et al, 2021 ). As the temperature increases in the future, the potential enhancement in evapotranspiration will be more pronounced than that of precipitation, leading to more water shortage and exacerbating desertification or desertification in this region ( Dai and Zhao, 2017 ; Su et al, 2018 ; Zhang Y. et al, 2023 ).…”

Understanding the effects of groundwater depth on soil microbiota and multiple soil functions is essential for ecological restoration and the implementation of groundwater conservation. The current impact of increased groundwater levels induced by drought on soil microbiota and multifunctionality remains ambiguous, which impedes our understanding of the sustainability of water-scarce ecosystems that heavily rely on groundwater resources. This study investigated the impacts of altered groundwater depths on soil microbiota and multifunctionality in a semi-arid region. Three groundwater depth levels were studied, with different soil quality and soil moisture at each level. The deep groundwater treatment had negative impacts on diversity, network complexity of microbiota, and the relationships among microbial phylum unites. Increasing groundwater depth also changed composition of soil microbiota, reducing the relative abundance of dominant phyla including Proteobacteria and Ascomycota. Increasing groundwater depth led to changes in microbial community characteristics, which are strongly related to alterations in soil multifunctionality. Overall, our results suggest that groundwater depth had a strongly effect on soil microbiota and functionality.
