分布式水文模型是水文模型的发展趋势,南京水文研究所模型(NRIHM)是架构灵活的集总式水文模型,为探索基于NRIHM的分布式水文模型在湿润流域开展水文模拟的可行性与适应性,在湿润地区南大洼—沙河集嵌套流域开展了相关研究。首先基于NRIHM产流模型构建思路构建了一层产流模型与二层产流模型,利用天然试验流域观测成果进行了栅格点尺度的产流模拟验证,对比模拟结果发现二层-抛物线的组合方式模拟效果更优。基于此种产流计算方法,构建了具有二层土壤结构的分布式水文模型,以长江滁河水系沙河集水库以上集水区为研究流域开展应用,率定期和验证期平均确定性系数分别为0.80和0.86,平均洪峰、洪量相对误差也均低于20%,表明该模型能够较好模拟实际径流过程,初步证明了该模型在湿润地区具有较好的适用性。

Due to the mutual repulsion between their hydrophilic surface terminations and the high surface energy facilitating their ran-dom restacking,2D MXene nanosheets usually cannot self-assemble into 3D macroscopic gels with various applications in the absence of proper linking *** this work,a rapid spontaneous gelation of Ti3C2Tx MXene with a very low dispersion concentration of 0.5 mg mL^(-1) into multifunctional architectures under moderate centrifugation is *** as-prepared MXene gels exhibit reconfigurable internal structures and tunable rheological,tribological,electrochemical,infrared-emissive and photothermal-conversion properties based on the pH-induced changes in the surface chemistry of Ti_(3)C_(2)T_(x) *** adopting a gel with optimized pH value,high lubrication,exceptional specific capacitances(~635 and~408 F g^(-1) at 5 and 100 mV s^(-1),respectively),long-term capacitance retention(~96.7%after 10,000 cycles)and high-precision screen-or extrusion-printing into different high-resolution anticounterfeiting patterns can be achieved,thus displaying extensive potential applications in the fields of semi-solid lubrication,control-lable devices,supercapacitors,information encryption and infrared camouflaging.

产业是乡村振兴的重要引擎,也是促进民族地区共同富裕、铸牢中华民族共同体意识的基础支撑。研究发现,民族地区乡村产业振兴影响铸牢中华民族共同体意识具有内在的逻辑,当前民族地区乡村产业振兴虽然取得了一定的成效,但仍然存在基础设施瓶颈问题突出、产业融合深度不够、要素分配不协调、利益联结机制不紧密等诸多亟须解决的问题。下一步,应加快民族地区乡村产业发展,坚定走高质量发展、特色发展、融合发展、富民之路,推动乡村产业实现质的有效提升和量的合理增长,在乡村产业振兴中促进各民族走向共同富裕、实现现代化,促进铸牢中华民族共同体意识。
