Large-scale construction of high-standard farmland with high capacity for resisting drought or water logging prime farmland is an important task of the current land consolidation in China. The purpose of this paper is to analyse the anti-disaster ability of farmland. The method for comprehensive evaluation of the natural disaster risk of agricultural production is selected to zone the well-facilitied capital farmland. Based on the variable fuzzy sets theory, this article uses GIS technical to divide comprehensive risk level and zone construction area of well-facilitied capital farmland according to risk intensity and feasibility of land consolidation. Taking Guanzhong region as an example, some conclusions are drawn: 1) The uncertainty of risk assessment can be reduced by using the variable fuzzy sets theory. 2) The risk assessment result was jointly determined by hazard and vulnerability, which provide the basis for selecting high-standard construction of prime farmland suitable areas. 3) Comprehensive risk level, the extent of concentrated contiguous and consolidation potential jointly determine the timing of land consolidation. It can provide a reference for zoning the construction area of well-facilitied capital farmland and for a better land consolidation plan.

Key words: Guanzhong region, agricultural disaster risk, variable fuzzy sets, construction areas for well-facilitied capital farmland
