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 researchers subjective experiences in ecological risks evaluation.
