摘要
本文重点介绍了基于测绘手段的地质灾害定量的各种原理与方法,并结合实例进行了具体的分析,同时也加以扩展了新的内容。在所介绍方法里面,主要分别介绍了传统的常规测绘方法与新技术与新仪器的测绘方法两个方面的内容,本文对地质灾害的定量都是通过计算地灾发生区的滑动土方量或者土方量的大小来实现的。
目前,我国对各类自然灾害的预防、求援和重建工作十分重视,主张以“预防为主,防治结合”的方针面对地质灾害,地质灾害的定量,可以优化防灾方案,降低救灾成本,还可为后期地质灾害的治理提供科学的数据依据,基于测绘手段的地质灾害定量显得更加具有直观性与利用价值,随着“3S”技术的出现跟计算机的快速发展,基于测绘手段的地质灾害定量方法也得到了快速发展,“3S”技术和GPS也应用到了地质灾害定量当中。所以,基于测绘手段的地质灾害定量方法会得到更大的发展,应用的领域也会变得更大。本文的第一章为前言部分,第二章分解介绍了各种不同的地质灾害定量方法,第三章为总结部分,对地质灾害定量的未来发展也做了展望,第四章是致谢部分。

ABSTRACT
This paper focuses on mapping quantitative means of geological disasters in various principles and methods, and to extend the new content. In all methods which mainly introduced the traditional mapping methods and new technology mapping method, this paper quantitatively geological disasters are occurring by calculating the area of disaster or sliding earthwork earthwork to achieve.
At present, our country for all kinds of natural disaster prevention, aid and reconstruction work very seriously, and advocated for prevention and control of "prevention first, combining" policy in the face of geological disasters, geological disasters of quantitative, can optimize the disaster prevention plan and reduce the cost of relief can be late for the management of geological disasters provide scientific data basis, based on the method of surveying and mapping of quantitative geological disaster is more intuitive and the use value, with the emergence of "3 s" technology and the rapid development puter, based on the method of surveying and mapping of geological disasters quantitative method also obtained fast development, the "3 s" technology and GPS are applied to quantitative geological disasters. So, geological disasters quantitative method based on the method of surveying and mapping will be greater development, and application of the field will e more big.
