“…China has the most research studies on paddy field utilization, followed by Japan, the United States, and India [26]. While case study areas in China mostly focus on the plains [27][28][29], and tend to be located within the northeastern plains [30], there is a lack of studies on IBPFU in the karst mountains of southwest China. Research methods commonly include standard deviational ellipse analysis, kernel density estimation, landscape index models, spatial overlay, autocorrelation analysis [6,31], etc.…”

China’s southwestern karst area exhibits many mountains and little flat lands, and intermountain basins (IBs) (locally named “bazi”) are one of their typical landform types. Comparative studies on land use in the core of typical landforms in karst mountain areas are relatively lacking. Studying the evolution and transformation patterns of intermountain basin paddy fields use (IBPFU) to optimize land resources in mountainous areas is important. Based on structural and functional perspectives, this study established a research framework on the evolution and transformation of IBPFU in karst mountainous areas, and analyzed the evolution and transformation patterns of IBPFU in Guizhou Province from 1966 to 2020 by measuring land use change and applying the moving window method and morphological spatial pattern analysis (MSPA) model. The study showed that the evolution of IBPFU is characterized by reversibility and irreversibility, diversity, and stages. The transition of IBPFU requires a trade-off among regional socioeconomic development, ecological protection, and food security. The commonality of land use transitions in IB and sloped land (SL) is reflected in the diversity of their land use functions. This study provides a reference for a comprehensive understanding of land use transitions and sustainable development in the mountainous karst regions of southwest China by providing in-depth examinations of the land use transition of IB, which is different from SL, via the long time series evolution of core land use types. The research framework and research method constructed here also apply to other regions.

“…Unlike the plains, the topography is the most important factor affecting the evolution of cultivated land in mountainous areas [22]. However, current research is often based on county and other macro scales and mainly focuses on eastern China [23][24][25]. There is insufficient research on land-use transformation and its further effects on special landform types in the mountainous regions of Southwest China.…”

Intermountain basins are the granaries of the karst mountains of southwest China. Revealing the process and trend of land-use transformation in typical mountainous “granaries” is of great significance to optimizing land-use, food security, and rural revitalization in the karst mountains of southwest China. Lianjiang basin in Huishui County is the largest in Guizhou Province of southwest China, and a typical mountainous “granary” is used as a case study area. Based on seven periods of high-definition remote sensing images from 1966 to 2020 and on-the-spot investigation, we adopt the analysis methods of landscape pattern, moving window, and buffer zone and conduct an in-depth study on the spatial evolution of land-use and the land-use transformation law of the typical “granaries” of karst mountainous areas in southwest China from the perspectives of changes in the quantity of land-use, changes in the types of land-use, and changes in the landscape pattern. The results showed that the transformation of land-use in the basin was mainly manifested in the transformation of the function of cultivated land and the diversification of the function of cultivated land. The landscape pattern of the basin was gradually transformed from traditional rural landscape to modern agricultural landscape. The gradient effect of land-use evolution and transformation in the study basin was obvious. Traffic, location, and land resources significantly affect land-use transformation in the basin. Based on the above analysis, this paper proposes that the “granary” basins in karst mountainous areas should optimize the land-use of the basin by the trade-off between regional socio-economic development, ecological protection, and food security. The results of this paper provide a reference for land-use optimization and rural development in the granary-type basins and other similar areas in the karst mountains of southwest China.

“…The term of arable land "red line" proposed by the Chinese government, should be strictly used as the baseline for arable land protection (Zhou and Lv, 2020;Qian et al, 2021). From an ecological landscape perspective, arable land can also contribute to an ornamental landscape (Shifaw et al, 2019). Arable land is an important factor in the rural landscape and can be used to enhance diversity with mountains and lakes (Jiang et al, 2021).…”

Dominant landscape characteristics of the arable land red line in Donggang, China

et al. 2022

In the face of endless idle and even abandoned farmland, it is trying to protect farmland resources and ensure food supply by determining the bottom line (red line) of arable land that cannot be changed in use. The red line has landscape characteristics and functions, but there remain limited understandings of how to judge the dominant landscape characteristics of cultivated land. Therefore, this study divides landscape characteristics into aesthetic value and stability according to landscape pattern. A comprehensive evaluation system was developed to explore the dominant landscape features of the cultivated resources based on a multi-factor comprehensive evaluation. On this basis, this study conducts an empirical study in Donggang, a coastal city in China. The results show that cultivated land resources with high aesthetic value are distributed near cities, major roads, and important natural resources. The cultivated land resources with greater continuity and compatibility with adjacent plots are relatively stable, mainly paddy fields. The red line of cultivated land should focus on the characteristics of cultivated land stability. At the same time, the aesthetic value of cultivated land resources is also an important factor (related degree is 0.852). According to this evaluation system, the dominant area of arable land protection in Donggang City is 88,027.21hm2, which is the preferred area for the red line of arable land.
