Landsenses ecology is a scientific discipline mainly focusing on land-use planning, construction and management towards sustainable development based on ecological principles, with natural elements, physical and physiological senses, social economy, as well as processes and risks in consideration. Unreasonable resource utilization and land development often bring various ecological risks, which leads to problems in ecological security. The main research content of landsenses ecology involves land-use, and its goal is human vision and social needs related to sustainable development. To some extent, landsenses ecology consists with ecological security researches especially in their goals, basic principles, study scales and contents, so it is necessary to combine landsenses ecology with ecological security research. Based on the brief analysis of the connotation and main characteristics of ecological security, we discussed how to apply the idea and method of landsenses ecology into ecological security researches in this paper. Therefore, the primary methods in landsenses ecology, like melioration models, mix-marching data, and Internet of Things can also be adopted in data acquisition, evaluation and prediction, and modelling of ecological security researches. With the development of landscape ecology research, landsenses ecology could expand its concerns from land-use to the construction and maintenance of ecological security pattern, which can better link human vision and welfare to land-uses, habitat quality and ecological security so as to contribute to a sustainable development of the region.
