Neighboring / Adjacent Coupling Relationship Between Urbanization and Farmland Safety Based on the Decoupling Theory

当前我国快速城市化推进对半城市化、农村等近程区域分布的耕地产生直接、强烈的影响,也对耕地安全造成强大的胁迫效应。为此,构建城市化-耕地安全综合评; 价指标体系,分别计算城市化指数和耕地安全胁迫指数,并基于脱钩理论方法对城市化水平与耕地安全水平的近程耦合关系进行量化分析。以江苏省连云港市为例,; 定量分析20002014年间其城市化水平与耕地安全的脱钩-耦合关系及耕地安全对城市化进程的响应程度。结果表明,; 20002014年间,连云港市城市化指数持续增高,耕地安全胁迫指数波动降低;; 20002007年为强脱钩、弱脱钩、扩张负脱钩及扩张脱钩的波动状态;; 20082014年呈更加强烈的波动状态,包括20082012年的强脱钩和2013年的扩张负脱钩状态,这反映出区域发展规划、土地利用规划和城市总体; 规划的实施对这一典型近程耦合系统产生了较大影响。研究期内连云港市城市化水平大幅提高,耕地安全所受胁迫程度不断降低,两者虽总体呈强脱钩关系,但仍需; 注意近程耦合结果波动性较大所揭示的不确定性问题,需要谨慎权衡城市化相关政策对耕地安全的影响。与过去的宏观、单一指标模型相比,基于近程耦合关系提出; 的多指标脱钩-耦合模型更具综合性,能更加全面、精细化分析快速城市化进程与耕地安全保护之间的复杂关系,为半城市化地区景观安全格局评估提供支撑,为城; 市化与耕地保护之间的协调发展提供决策支持。The current rapid development of urbanization in China has directly and; seriously affected farmlands distribution in its para-urbanized; neighboring /adjacent regions,and also posed severe stresses on safety; of these land. It is,therefore,essential to build up a comprehensive; urbanization and farmland safety assessment indicator system,work out; quantitatively urbanization index and farmland safety stress index,and; analyze quantitatively neighboring coupling relations between; urbanization and arable land safety based on the decoupling theory and; method. A case study was conducted of Lianyungang City of Jiangsu; Province to explore quantitatively coupling-decoupling relationship; between urbanization and farmland safety and response of farmland safety; to the progress of urbanization during the period from 2000 to 2014.; Results show that during the study period,urbanization index of; Lianyungang City increased steadily,while farmland safety stress index; fluctuated with a declining trend. Their relationship displayed a wavy; trend from 2000 to 2007,i.e. strong decoupling-weak decoupling-expanding; negative decoupling-expanding connection and a strong fluctuation curve; from 2008 to 2014,including strong decoupling during 2008-2012 and; expanding negative decoupling in 2013,which reflects strong impacts of; the implementation of the regional development,land use and city overall; programs on this typical neighboring / adjacent coupling system. During; the study period,Lianyungang City made a huge and steady progress in; urbanization, while reducing fluctuation of its stress on farmland; safety. Though the two posed a strong decoupling relationship,the; problem of uncertainty reflected in the huge fluctuation of the result; of the neighboring /adjacent decoupling calls for high attention,and the; influence urbanization had on farmland safety needs to be weighed; prudently. Compared to the macroscopic single indicator models used in; the past,the multi-index decoupling-coupling model built for the; neighboring coupling relationship is more comprehensive and capable of; analyzing the complex relationship between rapid urbanization and; protection of farmland safety in a more holistic and finer way.; Furthermore,it may provide theoretical support to landscape safety; assessment of para-urbanizd regions and to decision-making on harmonized; development of both urbanization and protection of farmland.国家自然科学基金; 厦门大学大学生创新创业训练计划; 中国科学院大学生创新实践训练计

齐拉西酮针剂治疗精神分裂症患者激越症状的Meta回归

【目的】基于已发表的齐拉西酮速效针剂对精神分裂症患者激越症状治疗的中英文文献，综合分析齐拉西酮针剂治疗激越症状的疗效及其相关影响因素。【方法】检索PubMed、EMBASE、Web of Knowledge、Cochrane Library、万方数据，中国期刊全文数据库，中国生物医学文献数据库（CBM disc）和维普网，应用随机临床试验报告的声明（CONSORT）为参照标准进行入组和评价文献，采用STATA软件进行Meta分析，以疗效的效应值为因变量，性别、年龄、治疗前PANSS量表总分、是否合并口服抗精神病药物等为协变量，进行Meta回归模型分析。【结果】根据GRADE方法，主要结局指标的证据水平为“中度”。共有14项研究纳入Meta分析和Meta回归，其中英文5篇、中文9篇。治疗前后样本量分别为1197和1149。随机效应Meta分析结果显示齐拉西酮针剂疗效显著［SMD=2.04，95%CI（1.47，2.61），P=0.000］。Meta回归分析显示，疗效与基线PANSS分数（t=5.57，P=0.011）、合并使用口服抗精神病药物（t=4.07，P=0.027）有关，与文献发表语种（t=-0.57，P=0.625）、年龄（t=0.74，P=0.539）无关，女性相对于男性有疗效更优的统计学差异趋势（t=-2.95，P=0.060）。【结论】齐拉西酮速效针剂治疗精神分裂症患者激越症状疗效良好，Meta回归模型显示治疗前病情较重、合并口服抗精神病药物的患者疗效更好
