农林类高校间的科研合作对于提高自身科研水平具有重要意义。选取我国28所农林类高校,以中国学术期刊全文数据库为数据来源,查找2011-2015年的论文合著数据,利用社会网络分析软件UCINET,绘制网络密度分析图,并计算各高校在论文合作网络中的程度中心性和中介中心性。研究发现,空间距离对农林高校合著影响比较明显,同城的或者距离近的高校合著论文数量明显多;属于“211”和“985”的农林学校发表论文基数大,合作篇数相应多,表明其他农林高校更倾向于与“211”和“985”学校合作;中国农业大学在农林类高校合作网络中处于中心地位,与其他高校联系最为频繁。
Scientific research cooperation between colleges and universities in agriculture and forestry is of great significance for improving their level of scientific research. Select 28 agriculture and forestry colleges and universities in our country, take the full-text database of Chinese academic journals as the data source, look for the data of the papers from 2011 to 2015, use the social network analysis software UCINET, draw the network density analysis chart, and calculate each university’s thesis cooperation network In the degree of central and intermediary center. The study found that spatial distance has a significant impact on the co-operation of colleges and universities of agriculture and forestry, with a significant number of co-authored theses in colleges and universities or in the vicinity; colleges and universities that belong to “211” and “985” The corresponding numbers indicate that other agroforestry colleges are more likely to cooperate with the “211” and “985” schools. China Agricultural University is at the center of the cooperation network of agroforestry colleges and has the most frequent contacts with other colleges and universities.
