The common character is to change the solid interspace shape of surface soil to build the rainwater converge section ( afflux section ) and crop planting section and force the runoff of converge section flow to crop planting section together with the runoff of crop plant section for crop use 共同的特点是改变地表空间立体微地形下垫面建设汇流区(也叫集流区)和作物种植区，将汇流区的雨水径流叠加汇集到种植区进行利用，既利用汇流区的来水，又利用集流区的雨水。
