我国耕地数量、质量与空间变化研究综述

Review on the Research of Quantity,Quality and Spatial Change of Cultivated Land in China

以中国期刊全文数据库(清华同方)的相关检索文献作为研究数据源,运用EXCEL软件和文献计量方法统计分析1994年以来该数据库收录的论文,并根据研究内容需要进行人为筛选分类,分析研究我国耕地数量、质量和空间变化的进展情况。结果表明:我国耕地变化研究经历了早期调查、动态监测以及土地利用和耕地变化综合研究三个发展阶段,目前研究还存在综合性与系统性不够、缺少定量指标和综合模型、研究尺度不全面、专业化研究不够和服务目标不全面等方面的问题。鉴于此,认为从多尺度构建具有空间、动态性的综合模型是今后耕地变化研究的重点。

Cultivated land is precious natural resources and assets, and its changes in quantity are the important contents in land use and land cover change studies. Based on the References of indexing China Academic Literature Full-text Database （Tsinghua Tongfang） , we sorted out the papers on man-made according to the research contents, analyzed these papers by using EXCEL software and making a statistical analysis of the research papers, summarized the research progresses for quantity, quality and spatial change of cultivated land at home from 1994 to 2010. It found that the research of cultivated land change had undergone three main development stages from early investigation, dynamic monitor to comprehensive study of land use and cultivated land change. This paper showed that the main problems were the lack of quantitative indicators and integrated model, incomprehensive and unsystematic study, incomprehensive scale, unprofessional study and insufficient target issues. As a conclusion, the future research should focus on formulate the integrated model with spatial and dynamic characteristic from the multi-scale. The results would play a great significance on the theory of cultivated land research.
