摘 要:研究目的:分析30年来土地整治的文献特点,提出土地整治的研究热点和主要进展,为中国土地整治的理论构建和深入研究提供科学依据。研究方法:文献资料法、归纳分析法和比较分析法。研究结果:30年来,中国土地整治文章数量总体上呈现先上升后下降的趋势;土地整治的研究尺度多为行政区尺度,对自然区域尺度和多尺度的研究较为少见;土地整治新增耕地的数量与质量研究、土地整治对生态环境的影响、土地整治与新农村建设和土地整治的效益评价是当前的研究热点。研究结论:中国土地整治研究取得了显著进展,但仍存在诸多不足,以下几方面的研究仍需加强:(1)重视土地整治本质内涵及核心理论与目标的研究;(2)提高土地整治数量与质量研究的同时注重对生态潜力以及粮食产能和粮食安全的研究;(3)深化土地整治对生态环境影响的研究;(4)探索土地整治效益评价的新方法;(5)注重土地整治研究中的尺度界定和多尺度耦合研究。The purpose of the paper is to explore the current situation, research scales and hot topics on land consolidation based on relevant papers that were gained from China National Knowledge Infrastructure(CNKI)and ISI Web of Science during the period of 1985-2015, and to explore the trend of research on land consolidation, in order to promote the development of land consolidation. Methods employed are documentary analysis, comparative analysis and comprehensive induction. The results indicate: 1)Numbers of Chinese literature on land consolidation in the latest 30 years rose up at first and went down later. 2)Almost all of the research scales of land consolidation were the administrative basis while the natural-scale and multi-scale research were rare. 3)Current land consolidation research in China is still in the exploratory stage, and the perfect theory system of consolidation is still under establishing. 4)There are 4 hot topics on land consolidation. ①Study on the quantity and quality of newly developed cultivated land. Enlarging the area of arable land and improving cultivated land quality are the basic requirements of land consolidation. Exploring land consolidation potential and the impact of land consolidation on grain productivity and food security are the cores of the quantity and quality study on newly developed cultivated land. ②The impact of land consolidation on regional ecology and environment. Current research focused on land consolidation's effect on soil, biodiversity and ecosystem services. ③ Land consolidation and new rural construction. Lots of previous researches have investigated the relationship between land consolidation and new rural construction, exploring the interactive coupling mechanism of them. @The benefit assessment of land consolidation. Currently the temporal-scale of benefit assessment applied is quite limited, and what we need in the benefit assessment of land consolidation is the long-term and large-scale observation. It is concluded that study on land cons
