“…From the perspective of comprehensive economic, ecological, and social values, mulberry-dyke and fish-pond systems are in line with sustainable development goals. With the popularization of the concept of large grains [43][44][45][46] and people's reflections on the intensification of agricultural systems [47][48][49][50], the comprehensive value of mulberry-dyke and fish-pond systems can become a new driving force for the regional economy.…”

Agricultural Heritage Systems exhibit multiple functions of agricultural production, ecological protection, and invaluable cultures and landscapes. The mulberry-dyke and fish-pond system is an important agricultural heritage. The Nanxun District of Huzhou, China is currently the area with the most complete and largest mulberry dykes and fish ponds in the world. In the past thirty years, with changes in labor force distribution and consumer demand, the production function of mulberry dyke and fish ponds has been challenged, and the production landscape as the carrier of farming culture has been threatened. Studying the spatial characteristics and optimization of mulberry dykes and fish ponds is of great significance to the sustainable development of the regional economy, culture, and environment. This study analyzes the spatial and temporal pattern evolution of mulberry dyke and fish ponds in Nanxun District since 1975. Based on the evaluation of the environmental carrying capacity of fish ponds, and according to the development goals of agricultural heritage inheritance and “planting and breeding balance”, the Future Land Use Simulation model is adopted to optimize the study area. The results show the following findings: (1) From 1975 to 2019, fish ponds and construction land increased significantly, mulberry fields and paddy fields decreased significantly, the scale of mulberry dykes and fish ponds decreased significantly, and the proportion of mulberry dykes and fish ponds was seriously unbalanced; (2) The overall scale of fish-pond breeding in Nanxun District is too large, and the proportion of farming and breeding needs to be adjusted; (3) In view of economic growth, cultural inheritance, and environmental protection, this paper simulates the spatial layout of mulberry dykes and fish ponds in 2035, and divides mulberry dykes and fish ponds in Nanxun District into a display area and an industrial development area. The display area restores the traditional mulberry dykes and fish ponds to the greatest extent. The industrial development zone maximizes the economic benefits of agriculture on the basis of “balancing planting and breeding”. Overall, this study provides a reference for protecting Huzhou mulberry-dyke and fish-pond agricultural heritage, optimizing agricultural production space, balancing human–environment relationship, and promoting regional sustainable development.

“…In terms of evaluation factor selection, researchers in recent years have begun to focus more on comprehensive multi-factor assessments, considering climate, soil, topography, and water resources [15][16][17][18]. Furthermore, factors related to ecology and the environment, like soil health, biodiversity, and ecosystem services, are gradually being incorporated into the evaluation system to achieve coordinated development between agricultural production and the ecological environment [19,20].…”

Conducting agricultural land suitability assessments (ALSA) scientifically is crucial for ensuring food security and fostering sustainable agricultural development. This study assessed the suitability of agricultural land in Taiyuan using a geographic information system (GIS) and the analytic hierarchy process (AHP), integrating factors such as topography, soil, water sources, and social conditions at a 1 km spatial resolution. The primary aim was to map the spatial distribution of agricultural land suitability and understand county-level variations. Given the irreversible impact of urban development on land use and the critical importance of ecological conservation, corresponding subtractions for urban and natural protected areas have been applied in this study during the assessment of agricultural land suitability. The findings revealed that Taiyuan’s agricultural land suitability generally falls within an intermediate range, without areas classified as completely unsuitable (lowest rank) or suitable (highest rank). The agricultural land suitability does not reach the extreme conditions of being “unsuitable” (lowest rank) nor “suitable” (highest rank), reflecting an overall intermediate potential for agricultural production across the entirety of Taiyuan. The spatial distribution indicates higher suitability in the east and lower in the west, with 33.1% of Taiyuan’s territorial area deemed relatively suitable, 61.3% moderately suitable, and only 5.6% generally suitable for agricultural production. Recommendations include focusing on high-economic-return crops in suitable areas, adopting drought-resistant varieties and enhancing agricultural infrastructure in moderately suitable areas, and prioritizing ecological conservation in generally suitable areas. Additionally, county-level strategies suggest differentiated agricultural models: agritourism and boutique agriculture in urban conflict areas like Qingxu and Wanbailin; cultivation of cold-resistant crops in ecologically fragile areas like Loufan; and sustainable agricultural practices like planting drought-resistant crops in water-scarce regions like Yangqu. This comprehensive assessment offers valuable insights for optimizing agricultural land allocation in Taiyuan, balancing economic development with ecological sustainability.
