| Abstract: |
| Protecting the cultivated land resource has a significant meaning to food security of national
strategy，and putting forward the research in protection zoning of cultivated land positively has an important
practical significance for reinforcing the management of cultivated land. Keeping the cultivated land uninvaded is
just the baseline，and looking for the investment of cultivation service provided by the farmers into the sustainable
cultivation，and strengthening the willingness of cultivation is the ultimate purpose. This paper explored the protection
zoning of cultivated land from the point of cultivation accessibility，and built up a model of it through introducing the
demand and supply of cultivation service，with the highlight explanation and calculation of the total supply，the total
demand，the ability of cultivation coefficient and the index of cultivation accessibility. The cultivation model was
used by taking the Ninghai County in Zhejiang Provence as the study area. The results showed that，the evaluation
index system built up by selecting types of indexes from the labor，economic and land factors could well describe the
actual situation of cultivation in Ninghai County. The protection zoning based on the index of cultivation accessibility
comprehensively took the quality of cultivated land and the cultivation distance into account，therefore it could
discriminate into the key protection zoning，the positive protection zoning and the normal protection zoning，and each
kind of protection zoning took different types of protection measures. The study can provide a new perspective for the
protection zoning of cultivated land. |
