Research status and hotspot of coal gangue utilized in agriculture:visual analysis based on CiteSpace
摘要
Abstract
Coal gangue is a solid waste generated during coal mining and washing processes,Coal gangue is a solid waste produced in the process of coal mining and washing,which contains trace elements such as potassium,iron,silicon,manganese,etc.required by plants and has the potential to be used in the agricultural field.Based on the lite-rature data retrieved from the core collection database of China National Knowledge Infrastructure(CNKI)and Web of Science(WOS),this paper used CiteSpace software to analyze the research in the field of agricultural utilization of coal gangue.The results show that the number of papers in the field of agricultural utilization of coal gangue has been on the rise since 1993.It has gone through three stages:initial exploration,improvement of disciplinary system,and rapid development,forming two key research fields of coal gangue and soil improvement,and coal gangue and heavy metals,with a total of six research directions.It is the main research hotspot to improve the properties of coal gangue matrix by adding exogenous substances and to prepare new fertilizers and soil conditioners by using coal gangue.Developing new coal gangue-based soil amendments,promoting the resource utilization of coal gangue,evaluating its impact on soil quality and ecosystem service function,and strengthening the composite application of coal gangue and other materials are important directions for future research on the agricultural utilization of coal gangue.关键词
