摘　　要：在高陡岩质边坡的生态修复工作中,最大的问题是在栽培完成后如何灌溉养护,以保证植物的成活,达到生态修复的目的。设计出了一套全新的智能自循环渗透灌溉系统。该系统以太阳能为动力,收集净化区域内地表雨水和地下水作为灌溉水,埋设湿度感应器实时掌控土壤状态,并及时反馈给智能水电控制系统进行总体控制,最终通过高分子纳米渗透管实现自动化精准灌溉。同时,灌溉水通过下渗和大气蒸发降雨进行反向补给,实现了水资源的循环利用,节约了宝贵的水资源。系统采用太阳能系统供电,无碳排放,契合国家碳中和理念,绿色环保,清洁节能。工程实例显示12个月坡面植被覆盖率约达70%,预测20 a维护和使用成本相对传统灌溉方式降低了约93%,生态修复效果良好,经济效益显著,可以为类似废弃矿山高陡岩质边坡的生态修复工作提供参考。In the ecological restoration of high and steep rock slopes,the biggest problem is how to irrigate and maintain after the cultivation to ensure the survival of plants and achieve the purpose of ecological restoration.A new intelligent selfcirculation infiltration irrigation system was designed.The system was powered by solar energy,collected surface rainwater and groundwater in the purification area as irrigation water,and embedded a humidity sensor to control the soil state in real time,and fed back to the intelligent hydropower control system in time for overall control.Finally,automatic precision irrigation can be realized through polymer nano-permeable tubes.At the same time,the irrigation water can be recharged by infiltration and atmospheric evaporation rainfall,which realized the recycling of water resources and saved valuable water resources.The system,which had solar energy system power supply without carbon emission,was in line with the national concept of carbon neutrality,green environmental protection,clean and energy saving.The engineering example shows that the vegetation coverage rate on the slope is about 70%in 12 months.It is predicted that the maintenance cost in 20 years will be reduced by about 93%compared with the traditional irrigation method.The ecological restoration effect is good and the economic benefit is remarkable,which can provide a reference for the ecological restoration of high and steep rock slopes in similar abandoned mines.
