摘要:采用中国知网（CNKI）和Web of Science核心合集（WoS）两大数据库的文献计量分析工具，统计分析了中国科学院遗传与发育生物学研究所农业资源研究中心（以下简称"农业资源研究中心"）创建40年来科技论文发表情况，从文献角度，分析农业资源研究中心的研究基础、研究热点和研究趋势的变化历程。共检索到论文2 052篇，中文文献1 467篇、英文文献585篇。论文发文总量呈逐年增长趋势，前20年以中文论文为主，2005年达到峰值，之后出现回落的趋势，但年发文量基本保持在50篇左右。2002年以后，英文论文呈快速增长态势，2003-2017年以26.85%的年均增长率增加。被CNKI引用≥50次的论文有118篇，被WoS引用≥50次的论文有44篇。中文论文发表在235种期刊上，英文论文发表在237种期刊上；发文量前10的中文来源刊平均影响因子1.022，英文来源刊平均影响因子3.411。论文的资助基金主要来源是中国科学院知识创新工程基金、国家自然科学基金、国家重点基础研究发展计划（973计划）、国家高技术研究发展计划（863计划）、国家科技支撑计划等。国际合作基金项目呈逐年上升趋势，资助基金机构达到73个，出现频率较多的是中国科学院的国际合作项目、澳大利亚国际农业研究中心基金、国家留学基金和欧共体基金等。合作研究机构主要集中在河北、北京、山东、山西等地。与国外合作的研究单位主要集中在美国、日本、荷兰、澳大利亚、丹麦、巴基斯坦等国家。CiteSpace关键词共现分析显示，创建初期农业资源研究中心的研究内容少且较分散，体现在关键词数量少、相互联系弱。之后，研究主题不断增多，2000年左右达到峰值，关键词之间联系逐渐紧密。研究作物以小麦、玉米为主，研究区域集中在华北平原。目前气候变化的大背景下，研究内容主要集中于作物栽培、育种与分子生物学，农业水资源及其利用，农田生态系统及其碳、氮循环，及盐碱地土壤、水和植物的利用等方面。总之，农业资源研究中心在过去40年的发展中，取得了显著的研究成果，研究水平不断提高，形成了鲜明的研究特色。

Abstract:Published scientific papers included in China National Knowledge Infrastructure (CNKI) and the core collection of Web of Science (WoS) of Center for Agricultural Resources Research, Institute of Genetics and Developmental Biology, Chinese academy of Sciences (CARR) since 1978, when CARR was launched, were bibliometrically analyzed to reveal the changes in research hotspots and trends of CARR since its' establishment. The CNKI and WoS searching results showed 2 052 papers of researches conducted by CARR since 1978, of which 1 467 papers were in Chinese and included in CNKI, and 585 papers were in English and included in WoS. Annual published Chinese papers number increased and peaked in 2005, and then kept at around 50 though slightly decreased. Papers in English were mainly published after 2002 and increased quickly with annual increase rate of 26.85% from 2003 to 2017. There were 118 papers in Chinese and 44 papers in English cited more than 50 in CNKI and WoS, respectively. And Chinese papers were published in 235 journals, and English papers in 237 journals. The average impact factors of the Chinese journals and English journals publishing top 10 papers were 1.022 and 3.411, respectively. The papers were mainly supported by the Program of Knowledge Innovation of Chinese Academy of Sciences, National Natural Science Foundation of China, National Basic Research Program of China (973 Program), National High-tech R&D Program of China (863 Program) and National Key Technologies R&D Program of China. The international cooperation of CARR increased yearly, and there were 73 international cooperation funds supporting the researches of CARR, such as International Cooperation Project of Chinese Academy of Sciences, Fund of Australia International Agricultural Research Center, National Study Abroad Fund of China, European Community Fund. The institutions collaborating with CARR to publish scientific papers were mainly from Hebei Province, Beijing City, Shandong Province and Shanxi Province, while the international institutions were mainly from USA, Japan, Netherland, Australia, Denmark, Pakistan. Co-occurrence analysis of keywords of published papers based on CiteSpace showed that the keywords in the first ten years since CARR establishment were less with weak interconnection. After that, the research keywords increased and peaked around 2000. The interconnections among keywords were increasingly close. The studied crops were wheat and maize, the areas concentrated in the North China Plain. Under the climate change background, the research works of CARR now are mainly focusing on crop cultivation, breeding and molecular biology; water resources and water-saving agriculture; carbon and nitrogen recycle of agroecosystem; reclamation of salt soil land, and utilization of halophyte and salt water resources. In summary, CARR have formed its' special research area and made remarkable research achievements.
