Abstract: In the course of implementing the cultivated land requisition-compensation balance policy, the food security concept of “taking grain as the key link” makes China pursuit the quantity balance of cultivated land while neglect the role of land use types other than cultivated land in regional food security. This approach leads to not only significant difference between supplementary and occupied cultivated land, but also blind development of grasslands, woodlands and wetlands, and thus pays a big price for ecological environment. Based on the connotation of food security, this paper introduces the concept of arable land equivalent unit (ALEU) and food equivalent unit (FEU). Zhoushan City of Zhejiang Province is chosen as the research area. This paper analyzes the supply and demand capability of the ALEU in the study area, and puts forward corresponding policy implications for improving cultivated land requisition-compensation balance. The results are as follows: 1) With the concepts of ALEU and FEU, we can better unify the FEU of grain and aquiculture products and then unify the ALEU supplies from cultivated land and aquaculture water. 2) Under the influence of the decrease of cultivated land area and big area of cultivated land abandonment, the ALEU of cultivated land decreased by 37.3% in recent years. The aquaculture water area in the study area, meanwhile, is also shrinking, however, under the influence of the construction of standard aquaculture pond and the improvement of breeding technology, the ALEU of aquaculture pond increased by 18.3% in recent years. The ratio of the ALEU from cultivated land and aquaculture pond changed from 46:54 in 2009 to 31:69 in 2015. 3) Under three different living standards: adequately fed, well-off and prosperous, ALEU from cultivated land and aquaculture water are hard to meet the needs of permanent resident population in the study area. However, measures such as improving agriculture infrastructure, raising cultivated land multi-cropping index, building high-standard aquaculture ponds, and improving yield per unit area of aquaculture water can increase the ALEU from cultivated land and aquaculture water to 19 771.22 hm2 and then reduce the ALEU gap by around 35%. On the basis of the results, the paper puts forward some policy implications, such as changing the food safety concept, attaching importance to food supply capability of land types other than the cultivated land, exploring the diversified form and differentiated management policy of cultivated land requisition-compensation balance, promoting the construction of high-standard cultivated lands and high-standard aquaculture ponds, enhancing supply capability of ALEU from existing cultivated lands and aquaculture ponds.

Key words: arable land equivalent unit (ALEU), cultivated land requisition-compensation balance, food equivalent unit (FEU), policy implication, Zhoushan City
