Abstract:

The reclamation of cultivated land reserve resources is an important source for supplementing cultivated land, and it is also a significant measure for ensuring food security and promoting the sustainable utilization of land resources. The rational development and utilization of these resources are of great significance for promoting economic development and implementing the policy of balancing the occupation and supplementation of cultivated land. Taking the reserve resources of cultivated land created through reclamation in Fujian Province as the research object, this study selected 12 influencing factors from four dimensions: terrain, soil, location and plot, to analyze their quantity and quality from the perspectives of mountainous and coastal areas. And a hot spot analysis was conducted to explore the coordination of their quality and quantity in spatial distribution. The research results showed that the quantity of reserve resources of cultivated land created through reclamation in Fujian Province varied greatly in spatial distribution, presenting a spatial distribution characteristic of “more in the east and less in the west”, and mainly concentrated in coastal areas, mainly consisting of orchards and tea gardens. The quality of reserve resources of cultivated land created through reclamation in Fujian Province was generally high, and except for the soil dimension, the quality in coastal areas was better than that in mountainous areas. This was mainly due to the advantages of flat terrain, convenient transportation, and regular plots in coastal areas. Among various types of land, the quality and quantity of reserve resources of cultivated land created through reclamation in orchards, tea gardens, and pond surfaces had a significant positive correlation in space. Specifically, the quality and quantity of reserve resources of cultivated land created through reclamation in coastal areas were high, while they were low in mountainous areas. In addition, the distribution of reserve resources of cultivated land created through reclamation with high quality but low quantity, and low quality but high quantity was relatively small. This indicated that the quality and quantity of reserve resources of cultivated land created through reclamation in Fujian Province are relatively coordinated, and high-quality resources tend to be concentrated together. There were significant differences in the quality and quantity of reserve resources of cultivated land created through reclamation between mountainous and coastal areas in Fujian Province. Exploring the characteristics of their quantity, quality, and coordination were of great significance for the rational development and utilization of reserve resources of cultivated land, optimizing resource allocation, promoting coordinated regional development, and protecting cultivated land.
