Intensity Change in Cultivated Land Use in Shandong Province from 1980 to 2010

By using statistical analysis on the input and output of agricultural production, the intensity change in cultivated land use in Shandong province is analyzed. The results show that the multiple-cropping index is declining in recent years, and labor intensity is decreasing sharply while capital intensity is rising rapidly. From 1980 to 2010, the average annual growth rate of net income of main crops in Shandong province is 6.4%. The average level of land productivity is higher in economic crops than grain crops while the average level of labor productivity is higher in grain crops than economic crops. Land productivity has an obvious acceleration on farmer labor productivity. This has an important reference value for sustainable utilization of cultivated land in Shandong province.
