虚拟耕地资源与农业经济增长：作用机理及贡献份额研

虚拟耕地资源被广泛认为是缓解国内耕地资源压力和促进农业经济增长的重要举措之一。在论证虚拟耕地资源贸易对农业经济增长作用机理分析的基础上，计算1996~2018年中国主要农产品虚拟耕地资源贸易量，并对虚拟耕地资源对农业经济增长中的贡献份额进行实证分析，为调整对外贸易战略及优化耕地资源策略提供参考。结果表明：虚拟耕地资源可以在更大范围内实现耕地资源的优化配置；主要农产品贸易的巨大逆差决定了中国是虚拟耕地资源净进口大国，其中，油料是虚拟耕地资源净进口量最大的品种；虚拟耕地资源对农业经济增长的贡献率为0.26%，观点得到了佐证。同时，还提出了要试点实施虚拟耕地资源，全力以赴做好贸易政策调整战略；充分利用国内外“两种资源、两个市场”，倒逼主要农产品进行结构调整；努力构建虚拟耕地资源管理新模式，推动农业“走出去”与市场多元化结合等政策建议。

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.
