Abstract In order to change the condition of the traditional Landslide Remote Sensing, with low efficiency and survey precision, also having difficulty being improved, the author put forward the concept of “Digital Landslide” in 1999 after years of practices and exploration. This new concept makes the traditional geological landslide develop into a new “Digital Landslide”, which can be expressed in digital form and has a three-dimensional space, multidimensional time information and multiple elements. Digital Landslide technology system compose of four parts: the interpretation basic technology, the remote sensing identification technology, landslide database and model. In recent years, digital landslide technique has successfully been applied to the construction of large hydroelectric power station, mountain transportation line, regional development, environmental governance, earthquake resistance and disaster reduction. Besides, it has also been used in large-scale individual landslide investigation and research. Significant economic and social benefits have been achieved and effectively serves have been provided to the national disaster prevention and mitigation strategies. Tibet Pali River landslide and Tiantaixiang landslide in the east part of Sichuan province were used in this paper as examples to explain the innovative application of Digital Landslide Technology.
