摘要
Abstract
In order to grasp the research trends and changing law of global farmland protection,bibliometrical method,visualization software — Citespace and its auxiliary software are used in this paper.The literature from CNKI and Web of Science about farmland protection was analyzed from the aspects of paper quantity,literature source,author distribution and citation condition to determine the theme and hot topic of farmland protection studies at home and abroad,including ecological security and biodiversity,etc..Results indicated that there were remarkable differences in paper quantity for farmland protection at home and abroad.Its changing featurres were affected obviously by policy environment and social cognition.In terms of literature quality,the impact factors and H index of Chinese literature of farmland protection were lower than that of the abroad ones,so the Chinese literature quality was relatively poorer and further improvement was necessary.In terms of author distribution,it was mainly concentrated in Europe,Asia (China) and North America.In terms of literature contents,farmland ecological protection was the global research hot topic.In terms of research direction,from global vision farmland protection involved broad area.Compared to western developed countries,Chinese research orientation combined natural science with social science.关键词
