Abstract
Land consolidation is widely used as a powerful tool for land use management in many countries. In order to objectively reveal the current research status in the field of land consolidation, this paper uses the Bibliometrix and Biblioshiny software packages, and VOSviewer to analyze the literature in the field of land consolidation in the last 20 years of the Web of Science Core Collection Database. The results show that: (1) In the past two decades, the annual publication of papers on land consolidation rose. It can be divided into three stages: 2000–2007 for the embryonic period, 2008–2012 for the long-term, and 2013–2020 for the high-yield period. (2) Land consolidation studies covered 68 countries or regions. The top three countries were China, Poland, and the United States. China and the United States played an important role in international cooperation in the field of land consolidation, and Turkey mainly conducted independent research in the field of land consolidation. (3) Land consolidation, reclamation, China, remote sensing, and land fragmentation were the high-frequency keywords in the field of land consolidation in recent years. (4) The research focusing on the field of land consolidation involved its development course, its impact on ecosystem services, and the evaluation of its benefits. (5) The theme of land consolidation studies was shunted and evolved over time, and nine evolution paths could be summarized in the studies of cultivated land fragmentation, development course of land consolidation, and impacts of land consolidation on soil. Finally, this paper predicted the future research directions of land consolidation: exploring new methods for evaluating the benefits of land consolidation, the scale effects of the impact of land consolidation on ecosystem services, research on the mechanism and comprehensive effects of land consolidation on soil, research on land consolidation and rural revitalization, and land consolidation theory research.
Highlights
Land is the basic resource for human survival and development [1,2]
2000–2007 The period was the was divided into three research stages: 2000–2007, 2008–2012, 2000–2007 germination period of land consolidation research
The results showed that the larger the scale of land reclamation, the more significant the increase in the horizontal line of the coast [29]
Summary
Land is the basic resource for human survival and development [1,2]. The rapid development of the social economy and population growth increase the demand for land.the limited land cannot provide more space and resources for human beings, and the contradiction between man and land becomes prominent [2,3]. Land is the basic resource for human survival and development [1,2]. The rapid development of the social economy and population growth increase the demand for land. The limited land cannot provide more space and resources for human beings, and the contradiction between man and land becomes prominent [2,3]. Food production is expected to increase by 70% (by 2050) to satisfy the growing population, and land requires a more sustainable management mode [5]. It demonstrates the need for the rational and efficient use of the world’s limited land resources in order to maximize the provision of products and services to the growing food needs of humankind
