| 摘 要： | 为了改变传统滑坡遥感技术方法效率低、调查精度难以提高的状况,经多年实践与探索,笔者于 1999 年提出了“数字滑坡”概念。该概念使传统的“地学滑坡”拓展为能以数字形式表达的,具有三维空间、“多维”时间信息的,由“多元”要素组成的“数字滑坡”。数字滑坡技术系统由滑坡解译基础技术、遥感识辨滑坡技术、滑坡数据库及滑坡模型4部分构成。多年来,数字滑坡技术已成功应用于我国大型水电站建设、山区交通线建设、区域开发环境治理以及抗震减灾等领域,也用于大规模个体滑坡调查研究,并取得了显著的经济和社会效益,有效服务于国家防灾减灾战略。该文主要以西藏帕里河及川东天台乡2个典型滑坡调查为例,阐述数字滑坡技术的创新应用。

| 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. |
