【目的】了解南疆不同枣产区土壤养分状况,明确各产区枣园土壤养分空间分布特征与肥力水平差异。【方法】以南疆4个枣主产区的373个枣园土壤为试验材料,测定分析土壤pH值、有机质、全氮、全磷、全钾、碱解氮、速效磷、速效钾等8项指标,基于修正后的内梅罗综合指数法并结合全国第二次土壤普查养分分级标准,对各产区土壤肥力进行综合评价。【结果】南疆枣主产区土壤pH介于7.05~8.63之间,属碱性土壤;有机质、全氮、碱解氮含量处于缺乏水平,分别为7.69 g·kg^(-1)、0.52 g·kg^(-1)、34.56 mg·kg^(-1);全磷、速效磷含量处于较丰富水平,分别为0.95 g·kg^(-1)、34.56 mg·kg^(-1);全钾含量处于极缺水平,为3.89 g·kg^(-1);速效钾含量处于中等水平,为134.77 mg·kg^(-1)。4个产区中,和田产区土壤有机质、全氮、全钾、碱解氮含量整体处于极缺水平,占比分别达85.06%、86.36%、99.35%、82.47%;而土壤全磷含量则达47.4%,属于丰富水平,占比最高;速效钾含量处于中等以上水平,占比高达94.81%。从空间分布特征来看,有机质、全氮和碱解氮含量整体呈西北部高、东南部低的趋势;全磷含量呈南北部高而东西部低的趋势;全钾含量呈东北部高、西南部低的趋势,速效磷含量则分布较为均衡,速效钾以东部产区土壤含量较低。【结论】阿克苏、巴州、喀什、和田产区综合肥力指数分别为1.21、1.04、1.19、0.97,肥力评价均为一般等级。南疆4个枣产区均需补充有机质和氮肥、控制磷肥、定量施钾肥,这一研究结果可为南疆枣产区科学平衡施肥提供科学依据。

目的:研究伊曲康唑对双氯芬酸钠在比格犬体内药动学参数的影响。方法:采用随机交叉试验方法,一组口服双氯芬酸钠,另一组同时口服双氯芬酸钠和伊曲康唑,清洗期1周后,两组交叉服用药物。用HPLC法测定比格犬合用伊曲康唑前后双氯芬酸的血药浓度,并对其药动学参数进行分析。结果:较单独给予双氯芬酸钠,合用伊曲康唑使双氯芬酸钠血药浓度曲线下面积(AUC_(0–∞))与最大血药浓度C_(max)分别降低31%和42%。而达峰时间和半衰期并无显著差异(P>0.05)。结论:伊曲康唑可能通过影响双氯芬酸的胃肠道吸收过程,来影响AUC_(0–∞)和C_(max)。

2023年12月18日甘肃省积石山县发生了M_(s)6.2地震,与以往同等级地震相比,其表现出“同震重灾”特征和引发了特殊流滑地质灾害。通过现场震害调查、走访受灾群众和搜集地质资料及相关文献,重点探讨了本次地震的发震背景和孕育地质条件,对比了宏观烈度分布特征及与仪器烈度差异,统计了不同民居房屋的典型震害特征及所占比例,调查了造成人员伤亡的主要成因;踏勘了次生流滑灾害宏观特征,对揭示其成因与触发条件提出了若干关键问题。结果表明:宏观与仪器烈度具有较为明显差异,原因主要为地形地质条件复杂、不同乡镇经济发展水平与房屋抗震设防能力差异及烈度仪布设缺乏统一标准;强震观测记录地表加速度明显大于2021年漾濞M_(s)6.4地震,烈度Ⅵ、Ⅶ、Ⅷ区面积分别为2022年芦山M_(s)6.1地震的2.3、1.5、2.5倍,为造成同级地震重灾的一个重要成因;泥流掩埋摧毁房屋、炕头相连淋浴间隔墙倒塌及地震发生在深夜是造成本次地震人员伤亡重的重要因素。流滑区域长约3 km,前后高程差约85 m,总面积约39万m^(2),漫出地面约3 m高,塌陷区残留若干孤岛,其可能为长期农田灌溉、地下水体富集、地震主振方向与泥流运动和天然沟谷方向相同等外在因素和黄土湿陷、土体液化等内在机理综合诱发,具体成灾诱因、物理机制和触发条件需多种手段联合验证。调查证明,按照抗震设防标准进行房屋建设和既有建筑加固,强化农村居民防震减灾意识和应急避难知识,是减轻地震造成人员伤亡的有效措施。
