“…Under the guidance of the economic reform and opening up, Pinglu gave full play to its resource advantages to develop the coal economy and entered the “rapid development stage dominated by the coal industry” [ 12 ]. During this period, Pinglu began to manage and rebuild the ecological environment damaged by mining since 1990 [ 42 , 43 ] and entered the “exploration stage of balanced development of economy, society and ecology” to establish the precedent of ecological restoration of Chinese mines. In 2012, the coal price began to drop, causing Pinglu, Shanxi Province, and even the coal resource-based towns across the country to face huge economic downward pressure.…”

The mine–agriculture–urban compound area formed under the combined effects of natural conditions, mineral resource endowments, and historical development is affected by severe man-made disturbances, and faces a prominent contradiction between economic development and ecological protection. Guiding the future development is an urgent problem in this region. This research used image data, logical reasoning, and empirical analysis, based on social and economic statistics and land-use data, to analyze the typical characteristics and problems of the social–ecological system in the mine–agriculture–urban compound area. Moreover, we identified future directions for the region guided by policy documents and built a philosophy framework for sustainable development and management of the region based on the concept of adaptability. The results showed the following: (1) At present, the output value of the coal industry accounts for 84.10% of the total regional output value, severely disturbing its social–ecological system, which needs to be protected and restored under human guidance and management. (2) The future development of this region depends on the one hand on green mining, and on the other hand, it is necessary to fully tap the potential of arable land and livestock farms to develop efficient and intensive agriculture. (3) The key contents of the social–ecological system management of the mine–agriculture–urban compound area include resolving the contradiction between development and protection, ensuring development, optimizing industrial structure, and safeguarding public interests. In conclusion, this research can expand the connotation and application scope of adaptive management and provide a reference for such areas facing the prominent contradiction between development and protection.

“…The publications of the top five countries accounted for 28.26%, 10.82%, 9.63%, 6.07%, and 3.52%, respectively, indicating those countries made the greatest contributions to the research on LRER. For example, in China, there are many studies on LRER in coal mining areas, and the research areas are mainly concentrated in ecologically fragile areas in Northwest China [4,[25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44] and high water level areas in Eastern China [6,[45][46][47][48][49][50][51][52]. The research focuses include reclamation of open-pit coal mines [8,38,39,[53][54][55][56][57][58], reclamation of coal mining subsidence sites [7,51,[59][60][61][62][63][64]…”

The mining of mineral resources has caused serious damage to land and significant pressure on ecological environment. During the repairing of damaged land and degraded ecosystems, there have been many pieces of literature related to land reclamation and ecological restoration (LRER) that have emerged. To understand the progress and prospect of LRER research, it is necessary to sort out such pieces of literature, analyze the current research status, and forecast the future research directions. Here, Bibliometrix R-package was used to analyze 2357 articles, which were derived from the core database of Web of Science, to explore the development of LRER from 1990 to 2022. The results are as follows. (1) The annual scientific output results show that both the number of articles published on LRER and the number of articles annually citied were increasing gradually from 1990 to 2022. (2) High-frequency keyword analysis indicates that heavy metal (Cd, Pb) pollution remediation is a research hotspot. The cluster analysis (CA) and multiple correspondence analysis (MCA) show that there are two clusters in the current research of LRER, in which one surrounds heavy metal pollution and the other focuses on ecological restoration of mining areas. The two clusters correspond to the remediation and ecological restoration (rehabilitation) stages of stepwise ecological restoration, respectively. Thematic evolution analysis shows that, for more than 30 years, mine drainage and heavy metal pollution treatment, soil reconstruction (soil profile reconstruction, soil improvement), and vegetation restoration have been the focus of research. (3) Future research should focus on the relationship between mine ecological restoration and carbon sequestration and the relationship between ecological restoration and biodiversity in mine areas. In addition, LRER technology exchange, international cooperation, and industrialization are also main directions of development. Generally, in this study, metrology software (Bibliometrix R-package 3.1.4) from the literature was used to sort out the relevant literature on LRER over the past 30 years so as to provide reference for future research on LRER.

“…#3 soil enzymes: The #3 cluster is concerned with the soil enzyme activity response of multi-plant combination systems in remediating soil contamination. Assessment of phytoex-traction should consider not only the rate of pollutant removal but also the remediation of soil health [56], a dynamic and complex functional structure that cannot be directly measured but can be quantified using soil quality indicators [57]. Soil enzyme activity plays an important role in soil nutrient cycling, accumulation, and decomposition, providing sufficient nitrogen (N) and phosphorus (P) for plant growth and development, primarily in the form of extracellular enzymes.…”

The bibliometric analysis technique was used to retrieve 232 relevant publications from the Web of Science core database published between 2002 and 2022. The basic characteristics of the literature were analyzed, and keyword co-occurrence analysis and literature co-citation analysis were performed. The results demonstrated the following: (1) The total number of publications on phytoremediation utilizing a multi-plant symbiosis system increased year by year, indicating that multi-plant symbiosis systems have garnered significant interest in the field of phytoremediation in recent years. (2) “Short rotation coppice” (#0), “straw” (#1), “heavy metal” (#2), “soil enzymes” (#3), “glomus caledonium” (#4), and “phenanthrene” (#5) comprise the research hotspots in this field both domestically and internationally, where the #0 clusters, #2 clusters, and #5 clusters indicate that the application of multi-plant combinations has not formed a new branch in the field of phytoremediation during 2007–2017. In addition, the #1 clusters, #3 clusters, and #4 clusters indicate that the safety of agricultural land, the mechanism of action of soil enzymes, and arbuscular mycorrhizal fungi comprise research hotspots in recent years. (3) “Heavy metal contamination” (#0), “agro-mining” (#1), “Leguminosae” (#2), “soil enzymes” (#3), “soil microbial community” (#4), and “Salix caprea” (#5) constitute the domestic and international knowledge base of this field, with a study of soil microbial communities regarded as the cutting-edge branch of this field. (4) The specific influencing factors of multi-plant symbiotic systems include plant diversity, interspecific relationships, and the gender of plant species, and the mechanisms of action include the plant–soil feedback mechanism, enhanced plant resistance mechanism, increased detoxification pathway, and plant–plant interaction mechanism. Finally, future research on phytoremediation using multi-plant symbiotic systems should focus on the following four aspects: exploring the applicable environment of multi-plant symbiotic systems as a remediation strategy; analyzing the remediation mechanism from multiple perspectives: atmosphere–plant–soil; combining physicochemical and biological technologies to improve remediation efficiency; and establishing a dynamic model to evaluate remediation effects.
