The Protection of Cultivated Land Based on Food Security in the Economic Area of Zhujiang Delta

摘要

At the stage of accelerating urbanization and industrialization the transfer of large amount of cultivated land into new industrial and urban built-up area is inevitable,especially in the developed area.As the cultivated land resources are the most basic material of production,the decrease of crop production that induced by the decrease of cultivated land leads to the food insecurity problem.Refer to time-series data on register population,food production and cultivated land area from 1993 to 2007 and other research results,though the predicted results from regression models,this paper attempts to propose the strategy could be adopted to protect the cultivated land based on food security for the developed area as the Economic Area of Zhujiang Delta.
