构建江汉平原农田生态安全系统预警的思考

江汉平原为中国南方四大富饶的平原之一,农业地位突出,但由于历史、人口、资源、发展方式等多种因素,江汉平原主体是湿地农业,农田生态很脆弱。在现今,随着经济的发展、全球变暖、农药的过度使用等多因素的影响,江汉平原的农田生态的稳定已受到严重危害,通过对江汉平原农业生态安全进行综述,阐明了农田生态安全对可持续发展的重要性以及构建农田生态安全预警系统的必要性,进而对建立生态安全预警系统的可行性、原则、基本方法进行初步研究,为江汉平原农田生态环境和可持续发展研究奠定基础。

The Think of Constructing Farmland Ecological Security Early Warning System in Jianghan Plain

The Jianghan Plain is one of four big affluent plains in south China,and its agricultural position is prominent.But due to various factors such as historical,population,resources,development mode and so on,its main agriculture is the wetland agriculture,meanwhile the farmland ecology is very fragile.Nowadays,with the effects of economic development,global warming,overuse of pesticide,and so on.farmland ecological stability in the Jianghan Plain has been heavily damaged.According to the review of farmland ecological security in the Jianghan Plain,the paper elucidated the importance of the farmland ecological security for sustainable development,as well as the necessity of early warning system's construction for farmland ecological security.Then preliminary study of feasibility,principle and basic method of early warning system's construction for farmland ecological security was carried on.It will lay a foundation for the study about farmland ecological environment and sustainable development in the Jianghan Plain.
