摘要:

大规模建设高产稳产、旱涝保收的高标准基本农田是当前土地整治的重要任务,论文从分析区域防灾减灾能力入手,将农业生产自然风险综合评价引入高标准基本农田建设区划定,在识别区域主要风险类型的基础上,应用可变模糊集理论,借助GIS 方法,划分综合风险等级,根据风险强度和整治可行性划定高标准基本农田建设区。结合对关中地区的实例分析,研究表明:①使用可变模糊集理论,综合考虑各单因子风险差异,可减少风险定量化的模糊不确定性;②综合风险由致灾因子危险性和承灾体脆弱性共同决定,风险评价结果可为筛选高标准基本农田建设适宜区提供依据;③综合风险等级、集中连片程度和整治潜力共同确定土地整治时序,可为划定高标准基本农田建设区和确定整治规划提供参考。

Abstract:

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
