Research hotspots and frontier analyses for agroforestry management

【Objective】Agroforestry is a sustainable land management system that helps solve current problems of resource depletion and land use contradiction. It is of great significance to continue implementation of agroforestry in China. 【Method】The analysis of research hotspots in this field will help clarify the current situation of domestic research, determine its own orientation and direction, and then improve research levels. Based on Web of Science database, the CiteSpace scientific citation analysis method and intelligent support system (ISS) of Chinese Academy of Engineering were applied to comprehensively analyze the retrieved research data in the field of global agroforestry management. The main research technologies and hotspots involved in this field were also analyzed and then summarized. 【Result】The pressure for agroforestry researches increases with improvement of the regional economic level. The keywords for global researches are system, management, diversity protection and stand growth. The research frontier of agroforestry management includes cultivation research, diversity research, spatial distribution research, energy flow research, and biodiversity protection. 【Conclusion】Researches on agroforestry in China should enhance extensive international cooperation and promote global macro researches. It will be a challenge and opportunity for future research to obtain high-precision stand structure parameters by using a low-cost and low-damage means and fully understand the interaction effects of plant interaction mechanisms and allelopathy. The agroforestry system has a broad development prospect in China. It will contribute significantly to the mitigation of global climate change.
