Summary: The study emphasizes the importance of cultivated land protection for food security, social stability, and sustainable development in China. It reviews the evolution of China's cultivated land protection policy, explores the spatial-temporal patterns of illegal cultivated land use, and analyzes the impact of various factors on illegal land use. The results show that while China has made efforts in protecting cultivated land, the quality of land has decreased, and there are regional disparities in the driving forces of land loss, with illegal land use being a significant factor.

Summary: Cultivated land area and fragmentation are crucial factors influencing food production in China. This study analyzed the spatial distribution and changes of cultivated land area and landscape fragmentation from a national perspective using land-cover data. The findings showed that the total cultivated land area in China decreased over time, but at a decreasing rate, while landscape fragmentation showed an increasing trend but also at a decreasing rate. Urban expansion and ecological protection programs were identified as major causes of these changes in cultivated land.

Summary: Since its establishment 70 years ago, China's cultivated land protection work has achieved remarkable results. Less than 10% of the world's cultivated land has supported 22% of the world's population, providing a foundation for the survival and development of 900 million peasants. However, the current Administrative Protection of Cultivated Land (APCL) still faces challenges in terms of norm-value and demand-efficacy.

Summary: Cultivated land is crucial for human survival and development, and its sustainable use is essential for food security and social stability. However, current policies lack focus on land use intensity and sustainability. This study estimated the cultivated land use intensity (CLUI) in Heilongjiang province from 2001 to 2015 using the HANPP framework. The results showed that CLUI varied among different crop types and had significant spatial heterogeneity. Fertilizers, pesticides, and plastic mulch were found to have a significant positive correlation with CLUI.

Summary: This study proposes an evaluation framework for the implementation effect of CLPP based on farmers' perception and uses AHP-entropy method and cloud model to evaluate the regional CLPP implementation effect in Xingning City, Guangdong Province. The results show that the comprehensive effect of CLPP is generally at a medium to good level, emphasizing the importance of improving farmers' comprehensive interests in future policy formulation. The cloud model used provides an objective evaluation result by mapping the uncertainty of each evaluation index, serving as a reference for relevant land use policy evaluation.

Summary: China, as the largest developing country, has given great importance to the protection of cultivated land. However, changes in cultivated land identification rules have resulted in a significant reduction in cultivated land. This study examines the actual change in cultivated land in Gaochun District and finds that 64.9% of the reduction in cultivated land is due to rule changes, indicating that the significant reduction in local cultivated land was mainly caused by changes in the rules.

Summary: The quantitative evaluation of land fallow suitability is crucial for the effective implementation of the fallow system in rural China. This study systematically assessed the cultivated areas suitable for fallow in Chongqing, China, using a comprehensive index (ILF). The results indicated a negative correlation between ILF values and population density, transportation proximity, and proportion of inclined areas, with a need for further investigation into geographical differences between karst and non-karst areas.

Summary: In order to reduce land conflicts and improve the coordination of human activities and land use, this study introduces a new framework for identifying the drivers of land expansion and evaluating multi-scenario simulation of land use. Using Mashan County in China as a case study, it indicates that the areas of cultivated land and grassland are decreasing, while the building area is increasing. Ecological land is primarily influenced by elevation, population density and temperature, while building land expansion is most influenced by gross domestic product (GDP). The results suggest that adopting the ecological protection scenario is an appropriate strategy for sustainable development in Mashan County.

Summary: Knowledge of cultivated land conservation and construction land expansion in China is lacking accurate and reliable data. This study analyzed the spatio-temporal patterns and driving forces of land change in China based on three nationwide land surveys. Results showed that China's cultivated land increased first and then decreased, with distinct regional variations. Construction land expanded nationwide, especially in rural settlements. The extensive and inefficient use of rural construction land poses a serious problem. The expansion of construction land was mainly driven by built-up areas and population growth, leading to a double failure of China's land policy.

Summary: This paper examines the causal effect of land use policy on employment growth in Chinese cities. The study finds that stricter Floor Area Ratio Regulation (FARR) leads to a reduction in employment growth, with more populated cities and labor-intensive manufacturing industries being more severely affected. Moreover, the impact of stricter FARR is less pronounced on state-owned firms compared to foreign-owned and privately-owned firms.

Summary: The protection and sustainable management of cultivated land are crucial for ecological balance. Spatially defined land-use strategies can help to ensure sustainable utilization of land resources. The water quality of the Yellow River has been affected by recent agricultural activities, posing a significant challenge to the Yellow River basin. Many policies have neglected ecosystem integrity. To address this, an ecological security pattern (ESP) was constructed in cities along the main course of the Yellow River in Henan Province, integrating cultivated land use and ecological protection.

Summary: This research examined the non-agriculturalization of cultivated land in four small towns in karst mountainous areas in southwest China. The findings showed that the Grain for Green Project has successfully reduced landscape ecological risk in these areas. Additionally, the conversion from cultivated land to non-agricultural land did not lead to a food crisis on a national scale. However, more social data collection is needed to fully understand the potential drawbacks of this conversion.

Summary: The Green Transition of Cultivated Land-use (GTCL) is a fundamental solution to ecological problems. This study evaluates the development level of GTCL in China and analyzes its effect on water, land, food, and carbon (WLFC). The results show regional differences in GTCL development and a fluctuating uptrend.

Summary: Sanjiang Plain, as an important grain-producing area in China, has experienced significant changes in cultivated land use and climatic conditions from 2000 to 2015. The study reveals that the long-term increase in temperature promotes the transformation of cultivated land from dry land to paddy field, while the increase in precipitation in June inhibits this trend.

Summary: The stability of land management rights significantly affects the cultivated land protection and quality improvement behavior of family farms, with factors such as transferred land ratio, contract types, and contract duration playing important roles. Family farms should improve their cultivated land protection behavior by regulating land transfer behavior, signing formal lease contracts, and extending the duration of lease contracts.
