中国耕地集约利用研究的文献计量分析

基于中国知识资源总库(CNKI)近30年来收录的有关耕地集约利用研究的中文文献,运用文献资料法、网络检索法和对比分析法,总结归纳中国耕地集约利用研究文献的主要研究内容、特点与研究的趋势。结果表明:1无论是中文期刊论文还是学位论文,相关成果都呈逐渐增加的趋势,但核心期刊载文量不多,研究领域的核心作者群体还没有形成,学术水平总体上还有待进一步提高;2理论研究的发展相对滞后于实证研究;3基于国家、省级等大尺度研究的文献相对较多,区域、市县的中尺度次之,农户和地块的小尺度最少,实证研究所涉及的区域,呈现不断扩大并趋于均衡的特点;4实证评价方法尚缺乏统一的理论规范,评价模型和评价指标繁多,且不同方法在不同理论背景与时空尺度下的适用性、实用性以及结果的验证等尚未引起足够的重视。应基于多视角、多领域和多尺度,加强对耕地集约利用机理的定量研究,强化研究方法的集成创新,以期为后续研究提供参考。

Quantitative Analysis of Literature on Intensive Use of Cultivated Land in China

Based on the data of intensive use of cultivated land in China from the published papers collected in literature database of CNKI, methods of documentation, network retrieval and comparison are employed to summarize the main contents, basic characteristics and developing trends of the researches on the intensive use of cultivated land in China. The results show that: 1) Both journal articles and thesis increased in recent 30 years, but the number of papers published in the core periodical was limited, and the core author group had not yet formed and academic level needs to be further promoted; 2)In general, the development of the theoretical research lags behind that of the empirical research; 3)The literatures based on the large scale research was more than these on the medium scale, while the small scale researches based on field plots were the least. The regions of empirical studies were extended and balanced gradually; 4) Although there are many kinds of evaluation models and evaluation indexes, the uniform theoretical standards need to be developed for the empirical research method, and more attentions should be paid to the applicability and practicability of different methods for different units and verification of results. The researches on the mechanisms with quantitative analysis from comprehensive perspective, scale and field and integrated innovation of research method should be enhanced in future.
