Research of ecological risks of land is becoming more popular recently. In order to study the research advances in ecological risks of land use, this paper, based on references, studies the research advances from study areas distribution, data collection and processing, land use analysis methods, ecological risks analysis theory and methods. Study areas are widely spreading with diversified sampling, of which the central and western China hold the majority, indicating the underdeveloped western China attracts more attention. “3S” technology provides lots of data. Descriptive analysis prevails, with fewer modeling. Calculation of ecological risks is based on internationally traditional ecological risk evaluation theory and scenic ecology. ERI can be used for a further temporal-spatial analysis of ecological risks and prevails. Studies on underdeveloped area are quite limited, this paper suggests boosting research in western. Quantitative study can reflect the ecological risk status of land use to some extent, but it needs more input in studying its complicated driving forces. Uncertainty analysis is suggested to be used to minimize the researchers subjective experiences in ecological risks evaluation.

This paper, based on industrial regulation theory, checks the economic and social effects of Shanxi’s coal integration in 2008—2009, and finds that the industrial integration policy took effect based on the public benefits, but resulted in some impacts. Governmental regulations interferes with markets will lead to economic loss, and loss in employment and taxation. From policy’s microscopic influence, countylevel and below and private companies undertake the major impacts, but provinciallevel and stateowned companies benefit from this integration. Centralgovernment companies are not affected. This paper’s conclusion has been validated, useful in understanding the relation between government and market.
