JCR分区表

1 chinese chemical lettersjcr大类分区

根据我所了解，JCR（Journal Citation Reports）是一个著名的期刊评价数据库，由Clarivate Analytics公司提供。它对全球范围内的科技期刊进行了广泛的评估和分类。

在JCR中，中国化学杂志通常被分为不同的大类，这些大类基于期刊的主题和研究领域进行划分。以下是一些可能的大类分区，这些分区可以帮助读者更好地定位和搜索相关的化学期刊：

1. "Chemistry, Multidisciplinary"（多学科化学）：这个大类包括了各个领域的化学研究，涵盖了从基础化学到应用化学的各种主题。

2. "Chemistry, Applied"（应用化学）：这个大类主要关注化学在实际应用中的应用和发展，例如材料化学、环境化学、食品化学等。

3. "Chemistry, Organic"（有机化学）：这个大类聚焦于有机化合物的合成、结构和性质等方面的研究。

4. "Chemistry, Inorganic & Nuclear"（无机与核化学）：这个大类涉及无机化合物、无机材料以及核化学等领域的研究。

5. "Chemistry, Physical"（物理化学）：这个大类关注化学物理学、表面科学和光谱学等方面的研究。

请注意，以上只是一些常见的大类分区，实际上JCR中可能还有其他更具体的细分领域。对于具体的期刊，您可以查阅JCR数据库或相关网站来获取更准确和详细的信息。

2020年最新中科院SCI分区公布，你的论文检索了吗

SCI有中科院分区，有JCR分区，分区越高说明用处越大。中科院的分区是每年更新，一般时间是在12月前后，2020年分区已于12-17日更新。2020年基础版分区表在秉承方法科学和数据客观的基础上，延续使用2019年基础版分区表的方法体系。

2020基础版分区表继续突出支持本土品牌期刊国际化的导向，形成了“中国SCI期刊评价方案”：主要措施包括调整提升中国期刊入选高区位的比例、扩大中国期刊入选基数（吸纳中国ESCI期刊进入分区表评价范围）和提升弱势学科期刊分区结果等。

对于综合性期刊，2020年基础版分区表采用2019年的工作方案：先将综合性期刊的每篇论文划分到一级学科，然后计算每篇论文在相应学科的影响力，最后汇总整本期刊的影响力水平。

目前，根据JCR分区表对SCI论文进行评价的模式已被国内部分高校和科研机构采纳，因为它有利于鼓励科研工作者向本学科的高级区域投稿。国内主流参考的SCI分区依据主要有中科院JCR分区表以及汤森路透JCR的Journal Ranking分区两种。其中，中科院期刊分区表则被更多的机构采纳以作为科研评价的指标。

中科院JCR分区表概况 由于不同学科之间的SCI期刊很难进行比较和评价，中国科学院国家科学图书馆世界科学前沿分析中心（原中国科学院文献情报中心），对目前SCI核心库加上扩展库期刊的影响力等因素，以年度和学科为单位，对SCI期刊进行4个等级的划分。一般而言，发表在1区和2区的SCI论文，通常被认为是该学科领域的比较重要的成果。

期刊学科划分

中科院JCR分区表对所有期刊的学科划分作出如下规定：

大类学科：医学、生物、农林科学、环境科学与生态学、化学、工程技术、数学、物理、地学、地学天文、社会科学、管理科学及综合性期刊，共13个大类。

小类学科：即JCR学科分类体系Journal Ranking确定的176个学科领域。
