摘要
选取化肥用量等23个指标,采用层次分析法测算江西省可持续食物安全度。结果表明,1978—2003年江西省可持续食物安全度逐步提高,目前食物处于安全水平。江西省食物生产因子、资源禀赋因子和气候因子安全水平较高,对食物安全较有保障;食物保障因子和社会经济因子安全水平偏低,是可持续食物安全的薄弱环节;可持续环境因子的安全水平正逐步加强,有利于提高可持续食物安全度。
Sustainable food safety in Jiangxi was assessed using the analytic hierarchy process (AHP) based on consumption of chemical fertilizers and other 22 indexes available. Results showed that it was increasing during the period of 1978─2003, and currently the food is safe. The province is quite high in safety level in terms of food production, resources and climate, which in turn provide some guarantee to food safety. However, the safety levels of its food guarantee factor and socio-economy factor are little bit lower, and the weakest links of sustainable food safety. The factor sustainable environment is rising in its safety level, which is contributive to enhancing sustainable food safety in Jiangxi.
