生态认知对长江流域渔民退捕意愿的影响研究基于鄱阳湖区的调研数据

流域禁捕是贯彻落实长江经济带发展战略和"共抓大保护、不搞大开发"的重要举措.渔民作为禁捕政策的最终执行者和落实者,其参与的积极性和主动性是政策顺利实施和推进的重要保障.基于计划行为理论,利用鄱阳湖区实地调查数据和结构方程模型,探讨了生态认知对渔民退捕意愿的影响及作用机理.研究发现:(1)生态认知对渔民退捕意愿有显著正向影响,即渔民生态认知水平越高,其参与禁捕政策的意愿越强;(2)生态认知的主观规范、行为态度、感知行为控制3个维度均对渔民退捕意愿具有显著正向影响,且3个维度两两之间也存在显著正向影响.其中,主观规范对渔民退捕意愿的影响最为显著;(3)主观规范中指令性规范对渔民参与禁捕的带动作用大于示范性规范;行为态度受渔民对政府禁捕政策的心理预期、生态修复保护与经济发展的重要性对比认知的影响较大;感知行为控制主要受到禁捕政策对家庭生产生活的影响程度及渔民参与禁捕政策能力的影响.为此,应建立有效的监督管理体系,提高指令性规范对渔民退捕的带动和引导作用,提高渔民对长江流域生态保护重要性的认知,营造浓厚的流域生态保护及积极参与禁捕的社会氛围,同时,制定适宜的转产转业政策,且将相关政策、补偿等严格落实到每位参与退捕的渔民,增强渔民对政府的信任程度,进而提高渔民退捕意愿.     

Combination with catalyzed Fe(0)-carbon microelectrolysis and activated carbon adsorption for advanced reclaimed water treatment: simultaneous nitrate and biorefractory organics removal

A process combining catalyzed Fe(0)-carbon microelectrolysis (IC-ME) with activated carbon (AC) adsorption was developed for advanced reclaimed water treatment. Simultaneous nitrate reduction and chemical oxygen demand (COD) removal were achieved, and the effects of composite catalyst (CC) addition, AC addition, and initial pH were investigated. The reaction kinetics and reaction mechanisms were calculated and analyzed. The results showed that CC addition could enhance the reduction rate of nitrate and effectively inhibit the production of ammonia. Moreover, AC addition increased the adsorption capacity of biorefractory organic compounds (BROs) and enhanced the degradation of BRO. The reduction of NO₃^?–N at different pH values was consistently greater than 96.9%, and NH₄⁺–N was suppressed by high pH. The presence of CC ensured the reaction rate of IC-ME at high pH. The reaction kinetics orders and constants were calculated. Catalyzed iron scrap (IS)-AC showed much better nitrate reduction and BRO degradation performances than IS-AC and AC. The IC-ME showed great potential for application to nitrate and BRO reduction in reclaimed water.
