[Purposes]This study aims to analyze the current situation of knowledge services in Chinese core journals of Geography and propose optimization strategies,providing a reference for the improvement and upgrading of knowledge services in scientific journals.[Methods]We focused on 20 core Chinese Geography journals listed in A Guide to the Core Journal of China(2020 Edition).Data were primarily collected from journals'official websites and WeChat official accounts regarding their specific forms of knowledge service.In addition,the knowledge services provided by the cluster platform of geographic scientific journals,the Journals of Chinese Geographic&Resource Science,were investigated.[Findings]In most core Chinese Geography journals,knowledge services are primarily concentrated on the first level of digital information services(basic services such as online publication,paper recommendation,and paper query services)and the second level of knowledge product services(knowledge search and knowledge discovery).The forms and quantity of third-level knowledge solutions(tools and applications,mobile and social services,multimedia services)are relatively limited.The current knowledge services provided by the Journals of Chinese Geographic&Resource Science focus on the second level of knowledge product services and also involve the third level of knowledge solutions,although some information updates are lagging.[Conclusions]Overall,the knowledge services of Chinese core journals in Geography are still in the initial stage and can be promoted in the future through the following approaches:improve easily implementable forms of knowledge service and enhance the user experience;develop tool services to support scientific research;integrate with new media technology to realize the"content+";expand the promotion and dissemination of key topics to better facilitate industry application and decision-making support;retain private domain traffic of the journals as a precise target for knowledge services;leverage the discipline cluster network to conduct knowledge services and establish a social service platform.

[Purposes] This paper aims to analyze the strategies for the promotion of Chinese academic journals on geographical resources, which is expected to enhance the media integration of Chinese academic journals. [Methods] A total of 27 quality Chinese academic journals on geographical resources were selected, and the application of mainstream media platforms（official website, WeChat platform, journal app, short video platform, and live broadcast platform） was analyzed based on the official websites or WeChat official accounts. [Findings] A total of 20 journals provide Rich HTML on the official websites, laying a basis for multi-dimensional publicity and promotion. However, most of the journals′ official websites still offer the electronic version of paper journals, lacking in-depth knowledge service. A total of 24 journals have WeChat official accounts, and 3 use cluster platforms to release news. The content pushed by WeChat is generally similar without deep processing or expansion. A few journals have posted short videos（5） and launched live streaming（7）. Short videos generally involve the sharing of article content, live streaming of conference, and journal publicity, and efforts should be intensified for secondary development and expansion of the content. The live streaming is common for conferences with journals as co-organizers and rare for content independently planed by journals with their own characteristics. On the whole, although 27 journals have all applied the multimedia platforms for promotion, more efforts should be made for the in-depth media integration. [Conclusions] There is a long way to go for the promotion of academic journals on geographical resources by media integration. Particularly, the media integration of the official websites should be emphasized and auxiliary channels should be selected for multi-matrix layout. In addition, the content should be designed according to user needs and periodic plans should be developed to ensure the sustainable supply and quality of content.

Purposes In order to analyze the current situation of the operation of WeChat video number of geoscience and technology journals. Methods 98 geoscience and technology core journals included in the Outline of Chinese Core Journals (2020) were taken as the research object, and the main information of WeChat video number opening, basic data, operation and other aspects of these journals were investigated. Findings : 1) The WeChat video account of the core scientific and technological journal of geosciences in Chinese is still in its early stages, with a low opening rate and generally late opening time; 2) The basic information of some accounts is incomplete, and the details need to be improved; 3) There are many problems in operation, such as unclear content orientation, simple conversion of most journal video content only in paper version, slightly rough production, generally unsatisfactory operation effect, low user interaction, lack of operation thinking of mass communication, etc. Overall, there are many problems in the operation of WeChat video accounts for core Chinese geosciences journals, which are also common problems in the operation of short video platforms for Chinese science and technology journals. Conclusions In general, the WeChat video number of the core geoscience journal has more room for improvement. First, we should improve the information and improve the credibility of the account; Secondly, the platform should be clearly positioned and a periodic push plan should be developed; Thirdly, we need to pay attention to drainage and interaction, and enhance the operational thinking of mass communication. Finally, the most important thing is to focus on content planning and maintain academic advantages.In addition, it is possible to consider building a geoscience journal cluster WeChat video account based on disciplines or publishing units/societies, integrating resources, and achieving a win-win situation.

[目的]分析地学中文核心期刊微信视频号运营现状,为更全面客观地探讨中国科技期刊微信视频号运营情况提供案例支撑.[方法]以《中文核心期刊要目总览(2020 年版)》收录的 98 种地学中文核心科技期刊为对象,主要调研其微信视频号开通情况、基本资料、运营现状等信息.[结果]地学中文核心期刊微信视频号还处于起步阶段,开通率较低,并且开通时间普遍偏晚.部分账号基本资料不完善,在细节上有待提升.视频号运营上存在较多问题,如:内容定位不明确,大部分视频内容仅是论文的简单转化;制作上略显粗糙,运营效果普遍不理想;用户交互程度较低,缺乏大众传播的运营思维等.这些问题也是中国科技期刊短视频平台运营的通病.[结论]地学中文核心期刊微信视频号需解决存在的共性问题,并基于学科特点和期刊特色专注做好内容策划.首先,应完善各项信息,提高账号可信度;其次,应对平台进行清晰定位,并制定周期性推送计划;再次,需增强大众传播的运营思维;从次,应基于地学学科角度选取具有吸引力且与受众相关的知识点,以易于理解的方式呈现更丰富的专业要素;最后,可考虑以学科或者出版单位/学会等为依托,搭建地学期刊集群微信视频号,整合资源,实现共赢.

[目的]探讨在专题/专刊出版成为期刊主要策略的背景下,专题/专刊对期刊影响力的提升效果.[方法]以《热带地理》为例,采用中国知网的统计数据,对比专题/专刊文章与自由来稿的被引频次和下载量,分析2014—2019年专题/专刊的实际效果.[结果](1)专题/专刊出版能有效提升期刊的外部声誉和影响力,有助于期刊获得国内评价体系的认可和国外数据库的收录.(2)总体而言,专题/专刊文章的被引频次略高于自由来稿,但两者差异并不明显.(3)专题/专刊文章下载量占期刊文章总下载量的63.6％,远高于自由来稿,可见专题/专刊能够引起广大作者、读者的关注,可显著地扩大学术传播范围.(4)专题/专刊的时效性、发表相似主题内容的间隔时间、命名的特色化、作者群体的覆盖面、文章数量、文章第一作者的职称和学历、宣传力度等是专题/专刊出版效果的重要影响因素.[结论]策划出版专题/专刊能有效提升期刊的外部声誉和影响力,但并非所有专题/专刊都能取得显著效果.除了做好内容之外,期刊应高度重视专题/专刊的宣传推广和知识服务.同时,必须强化期刊品牌建设,为期刊赢得优质人才,从而助力专题/专刊策划.
