The contradiction between population and cultivated land has always been an urgent global problem, and one that is particularly prominent in China. Based on the spatial–temporal evolution of cultivated land, this paper discusses the human–land contra...

Socioeconomic factors are extrinsic factors that drive spatial variability. They play an important role in land resource systems and sometimes are more important than that of the natural setting. The study aims to build a comprehensive framework for...

Since 2000, the Yangtze River Delta region has undergone a period of rapid urbanization in China. A large area of cultivated land has been converted into construction land, which greatly affects food security. The decrease in cultivated land caused b...

To ensure the sustainable utilization of cultivated land resources, it is essential to quantify and map the characteristics of construction land and cultivated land and analyze the mechanisms by which construction land expansion affects cultivated la...

The deviation of implementation of China’s cultivated land protection policy is the core problem urgently needing to be solved in the process of protecting the country’s cultivated land. This paper aims to explain the universality of this implementat...

With rapid and continuous population growth and the associated declining quality of cultivated land, food security in China has been attracting the attention of scholars both domestically and internationally. In recent decades, the implications of th...

Ensuring compliance with China’s “1.8 billion mu” (120 million hectares) cultivated land preservation policy is a fundamental goal of land policy. Northeast China has experienced significant cultivated land expansion due to rigorous...

Cultivated land serves as an important resource to ensure national food security, and how to allocate cultivated land reasonably and sustainably is an urgent problem that needs to be solved at present. Therefore, identifying land cultivability from t...

Cultivated land area and fragmentation are two crucial elements that influence food production in China. However, few studies have analyzed the fine-grained changes in both the area and the fragmentation of cultivated land from a national perspective...
