Technical model and demonstration of value-added utilization of ionic rare earth ore leaching site-Taking navel orange planting as an example
摘要
Abstract
Ionic rare earth ore is an important metal mineral resource and plays an indispensable role in the international market.However,the historical problems associated with the mining of ionic rare earth ores have caused severe soil erosion and soil functional degradation.The ecological problems of the leaching field have limited the further exploitation of ionic rare earth mining and the economic development in Ganzhou city.Therefore,it is necessary to explore a sustainable ecological restoration path for ionic rare earth mining leaching field as soon as possible.With navel orange planting and combined microbial restoration as the technical idea,after three years of integrated field research and demonstration,the vegetation coverage of the socking sites reached 95%,and the value-added revenue reached 5 015 800 ¥/(km2·a),forming a soil ecological restoration model of ionic rate earth mine wasteland,which integrated ecological function restoration and land value-added utilization.This model not only achieves ecological function restoration,but also generates economic benefits that can increase farmers'income and provide funding support for ecological restoration,realizing sustainable ecological restoration and providing technical support for achieving the goals of economic development and environmental protection in the Gannan region.关键词
