【 摘 要 】

Cultivated land refers to the land on which crops are grown, which are the basic resources and conditions for human survival. This paper uses the data of Shandong Statistical Yearbook (2001-2018) to study the spatial and temporal distribution pattern of cultivated land resources in Shandong Province by using GIS technology. The results show that the area of cultivated land between 2000 and 2016 is generally increasing, which is divided into attenuation and recovery. After adjusting the three stages, the cultivated land area has a downward trend after 2012, which is worthy of attention. From the perspective of the characteristics of the cultivated land resources, the cultivated land resources of the province are characterized by the lack of more than the east and the east, and the growth of the land reclamation rate is expanding to the east. From the perspective of the overall distribution of cultivated land resources, the average annual growth rate of cultivated land area in Shandong Province during the period from 2000 to 2016 was 0.89%, the average annual growth rate in Luzhongnan area was slightly faster at 1.07%, and the highest rate of land reclamation in northwestern Shandong was 60.96%, the most extensive cultivated area is Linyi City, the largest land reclamation rate is Liaocheng, the land reclamation rate is 67.50%, and about 2/3 of the land is cultivated land.
