| 摘 要： | 目的 从区域特征的角度出发，对我国采煤塌陷区土壤特性的现有研究进行分析，并尝试总结出区域间研究结果的异同点，以期为采煤塌陷地的修复与综合治理提供依据。 方法 采用CiteSpace和VOSviewer软件，自CNKI 和Web of Science核心数据库中选取1993 ~ 2021年采煤塌陷区土壤特性领域的相关文献，从关键词、研究区域等方面进行可视化分析。 结果 ① 近年来该领域发文数量总体呈增长趋势。② 研究区域的选择有明显的区域集中特征，依据其区域特性可划分为中东部平原区、西北风沙区、黄土沟壑区、西南山地丘陵区四个类型。③中东部平原矿区地势平坦，多位于高潜水位地区，土壤含水量受开采沉陷影响较大；黄土沟壑矿区地形多起伏，塌陷区地表变形严重，物理性黏粒减少，土壤容重减少；西北风沙矿区多位于干旱半干旱地区，生态环境脆弱，开采沉陷使得土壤细小颗粒流失，土壤容重显著降低；西南山地丘陵矿区主要分布在山区，雨量充沛，塌陷区土壤容重显著增加。 结论 煤炭开采沉陷对土壤特性的影响受多种因素的限制，使得土壤颗粒与结构、土壤含水量、土壤养分等特性发生变化，且在不同区域呈现出不同的变化规律。

| Abstract: | Objective The purpose of this paper is to analyze the existing research on soil characteristics of coal mining collapse areas in China from the perspective of regional characteristics, to summarize the similarities and differences of research results between regions, and to provide a basis for the restoration and comprehensive management of coal mining collapse areas. Method CiteSpace and VOSviewer software were used to select relevant literature in the field of soil properties in coal mining collapse areas from CNKI and Web of Science core databases from 1993 to 2021. Visual analysis was carried out in terms of keywords and areas of research. Result ① The number of publications in this field generally showed an increasing trend in recent years. ② The selection of the study areas had obvious regional concentration characteristics, and the regional characteristics could be divided into four types: central-eastern plain region, northwestern sandy region, loess gully region, and southwestern mountainous region. ③ The central-eastern plain mining region was flat and mostly located in the high diving area, and the soil water content was more affected by mining subsidence. The topography of the loess gully mining region was undulating, the surface deformation of the collapse area was serious, the physical clay particles were reduced, and the soil capacity decreased. The northwestern sandy mining region was mostly located in arid and semi-arid areas, the ecological environment was fragile, the mining subsidence made the loss of fine soil particles, and the soil capacity decreased significantly. The southwestern mountainous mining region was mainly distributed in the mountainous area, the rainfall is abundant, and the soil capacity of the coal mining collapse area increased significantly. Conclusion The influence of coal mining subsidence on soil properties is limited by a number of factors, resulting in changes in soil grain and structure, soil water content and soil nutrients, but showing different patterns of change in different areas. |
