农业水资源安全的定义及其内涵和外延

为了给农业水资源安全下一个比较明确的定义，同时给出这一定义的内涵和外延，本文在综述水安全、水资源安全、水环境安全3个概念不同的定义，辨析它们之间关系的基础上，推敲了农业水资源安全概念的组成要素，得出农业水资源安全应该是水资源的供应保障农业不受威胁，没有危险、危害和损失。这一定义的内涵包括农业水资源安全的自然属性、社会经济属性和人文属性3个方面。其外延涉及广义和狭义的农业水资源安全，以及由农业水资源安全引发的粮食安全、农业生态环境安全、农业经济安全、农村社会安全等。定义这一概念可以为开展农业水资源安全研究、确定农业水资源安全的理论框架、建立农业水资源安全评价体系提供一定的理论参考。
