Analyzing Spatio-Temporal Characteristics of Cultivated Land Fragmentation and Their Influencing Factors in a Rapidly Developing Region: A Case Study in Guangdong Province, China

Cultivated land fragmentation (CLF) is a key obstacle to agricultural development and has strong relationship with regional food security global sustainable development. However, few studies have analyzed the spatio-temporal distribution pattern evolution characteristics of CLF complex interactions among their influencing factors in rapidly developing regions. In this study, first, GlobeLand30 datasets were used obtain characteristic parameters cultivated counties Guangdong Province 2000, 2010, 2020. Then, linear weighted comprehensive evaluation model based on principal component analysis (PCA) was measure extent CLF. Finally, exploratory spatial data (ESDA) analyze CLF, geodetector (GD) random forest (RF) models explore difference The results showed that differences resources are relatively large agglomeration generally low. county scale mainly medium higher. overall shows an increasing trend from south north west east, randomness remains stable. From 2000 2020, continued intensify increased. result natural environment influenced by such as social, economic, interaction between very strong, dominated nonlinear enhancement. great significance for promoting intensive efficient utilization
