Abstract

Under the background of the sharp reduction of cultivated land resources and limited reserve resources of cultivated land, it is an inevitable trend to tap the potential and improve the intensive use of cultivated land. Taking Hubei Province as an example, using the method of energy value analysis, the intensive degree of cultivated land use is measured from the perspective of input indicators, and the labor intensive degree, mechanized intensive degree, fertilizer intensification degree, pesticide intensive degree and film intensive degree of cultivated land in 2011 are analyzed. Then, based on these five input energy values, the spatial pattern of cultivated land use intensification in the study area is analyzed. The results show that the agricultural machinery intensive degree accounts for more than 99% of the intensive use of cultivated land, and science and technology is an important breakthrough point for China to achieve agricultural modernization; the research area presents a spatial pattern of “intermediate high and low wings”. The study on the intensive use of regional cultivated land can better manage cultivated land resources, ensure food security, increase farmers' income and coordinate the sustainable development of regional economy.
