【摘要】以湖南为例从分散蓄水与扩容蓄水、即时蓄水与重复蓄水、分级截流与设阻截流等角度,分析了稻田养鱼的生态防灾机制,得出湖南宜鱼稻田87.0万hm2,以蓄水30 cm计算可蓄存107.9亿m3。通过重复蓄水、设阻蓄水,接纳多次降雨洪水,调节水分时空分布,创造减灾避灾的人工生态防灾系统,形成多物种共生共存的农田湿地生态系统,提高农田生态经济效益。更多还原

【Abstract】 We have analyzed the ecological disaster prevention mechanism in Hunan province in the aspect of decentralized water store and expanded water capacity,instant water store and repetitive water store,graded flow-block-up and barrier flow-block-up.The deduced result is that paddy field suitable for cultivating fish in Hunan is 87.0×104hm2 which can store up 107.9×108m3 of water in the depth of 30 cm.This sort of soil can create man-made ecological disaster prevention system of wetland paddy field by instant water store,repetitive water store,acceptance of rainfall and floods,adjusting time and space distribution of water resource.It can also improve ecological and economic benefits of paddy field.更多还原
