With the proposal of“dual carbon”goals, China′ s construction of an ecological civilization has entered a new stage with the focus on reducing carbon. The eastern grassland area of the eastern Inner Mongolia Autonomous Region plays an important role in ensuring national energy security, ecological security, and achieving the goal of“carbon neutrality”as scheduled. However, the ecological environment in this area is characterized by extreme cold, semi-arid conditions, and a scarcity of topsoil. Furthermore, the ecological environment problems caused by mineral resources exploitation seriously restrict the sustainable development of regional energy and ecological security. Therefore, it is necessary to perform research on ecological restoration of mines in the grassland area in eastern Inner Mongolia. This paper reviews the research process of mine ecological restoration at home and abroad, summarizes the existing research on mine ecological restoration and the advanced technologies of mine ecological restoration in the grassland area of eastern Inner Mongolia, and analyzes the path and mode of mine ecological restoration in the grassland area under the background of carbon neutrality. This paper preliminarily clarifies the existing problems and deficiencies in the research of mine ecological restoration in the eastern grassland area of Inner Mongolia and considers the prospects of future research trends, with the goal of providing reference for future generations to study the ecological restoration of mines in these grasslands and similar areas both at home and abroad.

As a raw material for clean energy supply for the new generation, the soybean is conducive to the realization of global energy transition and sustainable development in the context of "carbon neutrality". However, global warming has been affecting soybean yields in recent years. How to clarify the correlation between meteorological factors and soybean yields, so as to ensure the security of soybean growth and development and the stability of renewable energy development, is a key concern of the government and academia. Based on the data of temperature, precipitation, sunshine duration and active accumulated temperature during the soybean growing season in Hulunbuir, Inner Mongolia Autonomous Region from 1951 to 2019, and soybean yield data of the city from 1985 to 2019, this paper adopted statistical methods such as the Trend Analysis Method, the Rescaled Range Analysis Method and so on to analyze the trends of yield changes, characteristics of abrupt changes and periodic patterns of climate factors and soybean yields in Hulunbuir. A Pearson Correlation Analysis and a Grey Relation Analysis were used to explore the correlation between climatic factors and soybean yields, followed by a comprehensive impact model of the combined effect of temperature and precipitation on soybean yields established by the Method of Integral Regression. The results showed that temperature and active accumulated temperature are the dominant factors affecting soybean yields in Hulunbuir, while the decrease in precipitation is unfavorable to the improvement of soybean yields. Meanwhile, temperature and precipitation have different effects on the growth and development of the soybean at different stages. The conclusion of this paper is of great practical significance for Hulunbuir to promote the sustainable development of clean energy. [ABSTRACT FROM AUTHOR]
