“…We also compared our assessment results with our previous research in the middle reaches of the HRB, which evaluated land multifunctionality at the township scale (Meng et al, 2022). The spatial patterns of our land multifunctionality assessment were in accordance with those of our previous study.…”

Land systems in drylands have been experiencing increasing conflicts among multiple land functions. The improvement of one function is often at the cost of other functions, and trade-offs occur. Previous studies often cannot adequately address the fuzziness and lack an optimal benchmark when assessing land multifunctionality, and neglect the nonlinear features when quantifying the trade-offs. Taking the Heihe River Basin (HRB) in China as a study area, we applied the set pair analysis (SPA) to develop a novel framework for assessing land multifunctionality at a grid scale from the production-living ecological aspects. We then utilized the constraint line fitted with segmented quantile regression to identify the trade-offs among land functions.The results showed that our developed model could effectively measure land multifunctionality. The overall land multifunctionality in the HRB increased between 2000-2015, and the increased production and living functions made more contributions. From 2000 to 2015, the relationship between production function and ecological function changed from the status of synergy to trade-off, and the degree first increased and then decreased. The coupling coordination degree index showed that the coordination among land functions was high in the south and low in the north, which was mainly controlled by ecological functions. The effects of natural and anthropogenic drivers on land functions showed nonlinear characteristics, and thresholds existed for some factors showing the abrupt change in influence. We concluded that our research provides reliable and detailed information about the interactions among land functions, which is essential for sustainable land use and territorial spatial planning.

“…In terms of multifunction measurement of cultivated land, the comprehensive evaluation method of indicators [ 10 , 21 ], material quality evaluation method [ 20 , 22 ], value evaluation method [ 23 , 24 ], and other methods are used. At the national [ 9 , 25 ], provincial [ 26 ], municipal [ 27 ], county [ 10 , 28 ], village [ 29 , 30 ], and grid levels [ 31 ], the multi-functional evaluation and zoning of cultivated land are investigated using the methods of full arrangement polygons [ 32 ], spatial autocorrelation [ 33 ], coupling coordination degree modeling [ 5 , 34 ], and Spearman level correlation coefficients [ 35 ].…”

The material foundation of sustainable agricultural development is cultivated land resources, and their sustainable use is critical to fostering agricultural sustainability and guaranteeing national food security. In this paper, the multifunctional evaluation framework of the cultivated land system based on the “GESEL” model at the grid scale (5 km × 5 km) is constructed to explore the spatiotemporal evolution characteristics of a multifunctional cultivated land system in two lake plains and the trade-off and synergy between the functions. The five functions are all unstable in time scales, and their spatial distribution characteristics are also different. The trade-off and synergy between the multiple functions of the cultivated land system in the two lake plains from 2000 to 2019 showed significant spatial heterogeneity. Most of the functions were mainly collaborative, and a few were trade-offs. The two lake plains can be divided into four multi-functional cultivated land zones: a grain production leading zone, a distinctive agricultural planting zone, a high-efficiency agricultural development zone, and an ecological agricultural construction zone. This research puts forward some countermeasures and suggestions to promote the sustainable utilization of cultivated land resources.

“…It was defined as goods and services provided by different land use categories in order to meet the demands of human activities. Considerable progress had identified land use function from the aspects of production, living, and ecology, by establishing a comprehensive index system (Meng et al, 2022). Besides, some literatures measured the degree of human activities on land use (Howison et al, 2018;Yin et al, 2020;Zhou et al, 2022), and captured the changes in fixed input or economic output efficiency per unit of land in a certain administrative region (Guo and Shen, 2015;Jiang et al, 2021).…”

“…The trade-off is generally described as the status where a specific system benefits at the cost of others (Hamilton et al, 2019). A wealth of studies investigated the links and interactions among multiple natural ecosystem services (Howe et al, 2014;Cord et al, 2017;Geng et al, 2022), and some scholars recently explored the trade-offs/synergies between natural and artificial ecosystems such as multiple land use functions (Fan et al, 2021;Zhu et al, 2021;Meng et al, 2022), but it is relatively scarce to quantify the trade-offs and synergies of different land use characteristics. To fill this research gap, this article focused on the relationships between land use dominant and recessive morphologies.…”

The unprecedented urbanization recently has inevitably intensified the changes in land use morphology. However, current studies on land use primarily analyze a single morphology, ignoring the relationships between different land use morphologies. Taking the northern slope of the Tianshan Mountains (NSTM) as the study area, this article quantifies the spatiotemporal pattern of land use change, and estimates trade-offs and synergies between dominant (patch density, largest patch index, and landscape shape index) and recessive (land use efficiency, land use intensity, and agricultural non-point source pollution) morphologies to fully understand the dynamic characteristics of land use. Results showed bare areas and grassland were always predominant land use types, and land use change from 1990 to 2020 was characterized by the increase of impervious surfaces and the decrease of bare areas. The strongest trade-off was found between largest patch index and land use intensity, while the synergy between landscape shape index and land use intensity was strongest. There are significant disparities in terms of temporal and spatial patterns of trade-offs/synergies. The correlation coefficients in different study periods were much smaller than their estimations in the whole region, and the trade-offs/synergies in the eastern NSTM were basically identical with the whole relationships. The findings reveal the interactions among various land use characteristics, and provide significant references for coordinated land management and regional high-quality development.
