Empirical Study on Utilization Benefit of Cultivated Land in Changsha

Abstract:

In order to realize the status of cultivated land resources in Changsha and to protect cultivated land resources. According to output benefit coefficient, consumption and return coefficient, population and substitution coefficient and intensive cultivation coefficient, cultivated land utilization benefits were quantitatively analyzed in Changsha from 2002 to 2011. The results showed that: the trend of the quantity of cultivated land was upward in general in Changsha. But the quality of cultivated land decreased. At the same time, the output benefit of arable land was good in 2004, 2006 and 2008, but the rest of year was lower, and the tendency was dropping. On this basis, the effectiveness of the strategies was improved to use of arable land resources.
