现代农业灌溉减排模式的建立与应用

Establishment and application of modern agricultural irrigation reduction model

基于我国现代农业的经济发展模式,参照国内外相关研究成果,分析了现代农业面源污染的产生原因及其特征。从"源头控制、过程拦截、末端处理、灌溉回用、分区治理"等角度,提出了现代农业灌溉减排模式(MARIM)的构建方法,并通过环巢湖西北角的东大圩现代农业示范区工程进行实例验证。结果表明:MARIM模式可使上、中、下圩尾水中TN、TP的含量分别减少88.2%、89.6%、80.6%和89.1%、88.4%、82.6%,对现代农业面源污染控制与农业尾水再生利用具有显著的效果。

Based on the development pattern of modem agriculture in China, referring to relevant research conclusions from home and abroad, the cause and characteristic of modem agricultural non-point source pollution are analyzed. From the angles of ＂controlling at source, intercepting at process, disposing at end, recycling for irrigation, partition management＂, the construction method of modem agricultural irrigation reduction model （MARIM） is proposed. Moreover, an engineering example of Dongdawei modem agricultural demonstration zone around Chaohu Lake is observed to vali tail water near top, middle and bottom 82. 6%, respectively, which is highly reusing agriculture tail water. dating the system. The results indicate that the content of TN and TP in the of the dam is reduced by 88. 2%, 89. 6%, 80. 6% and 88. 2%, 88. 4%, efficient in controlling modem agricultural non-point source pollution and
