摘要
土地是不可再生资源,土地资源中的黑土资源尤为稀缺。由于农民长期高强度、不合理的粗放经营以及自然因素的作用,中国的黑土地正面临变贫瘠、变盐碱化等一系列问题,需要采取有效措施保护黑土地。以中国知网(CNKI)的期刊为数据源,借助软件对作者、热点期刊、关键词绘制图谱并进行分析,筛选得到2010—2020年的336篇相关文献,近11年发文量逐年增长;研究学者607位,以丁一为代表;发文期刊共有160家,《吉林农业》排在首位;关键词共818个,频次最高的是保护。研究发现,黑土地唯有用养结合才能长足发展,通过建立完善的法律机制、广泛宣传、加大监督力度、加大政策扶持等方式发挥农民的积极性。
Land is a nonrenewable resource,among which black soil resources are particularly scarce.Due to the long-term high-intensity,unreasonable extensive management of farmers and the role of natural factors,China’s black soil is facing a series of problems such as becoming barren and salinization.Therefore,effective measures need to be taken to protect the black soil.Taking CNKI journals as the data source,the author,hot journals and keywords were mapped and analyzed with the help of software,336 relevant articles were screened from 2010 to 2020,and the number of articles published has increased year by year in recent 11 years.There are 607 research scholars,represented by Ding Yi;there are 160 journals,and Jilin Agriculture ranks first;there are 818 keywords in total,and the most frequent is protection.It was found that only the combination of use and maintenance can make great progress in black soil,farmers’ enthusiasm can be brought into play by establishing a perfect legal mechanism,extensive publicity,strengthening supervision and increasing policy support.
