铜川市耀州区地质灾害预警方法研究

铜川市耀州区位于陕北黄土高原南缘，具有黄土塬区地质灾害发生发展的共同特点，属地质灾害多发区之一。根据该区地质环境背景，对其进行地质灾害易发度分区；结合人口、地面设施、土地利用现状等因素，进行地质灾害危害度分区。将易发度分区图与危害度分区图进行叠加分析，获得该区地质灾害防治分区图。利用该区和邻近地区历史上已发生的地质灾害与降水关系实际数据，建立该区地质灾害气象预警判断图，再依据当地实际降水量来判断地质灾害发生的可能性．发出地质灾害预警预报，以便采取有效的防治措施，将地质灾害造成的损失降到最低。

A Study on Geological Hazard Early Warning in Yaozhou District, Tongchuan City

The Yaozhou District of Tongehuan City is situated at south margin of northern Shaanxi loess plateau and provided with common characters of geological hazard occurring and development in loess tableland and belong to geological hazard frequently occurring area. Based on geologic setting carried out hazard possibility partition; based on population, ground installation and land use actuality carried out hazard impairment partition. Overlaid the two maps and analyzed then obtained a hazard controlling zonation map of the area. By the use of actual data of relation between happened geological hazard and atmospheric precipitation in history of the area and contiguous area make out geological hazard meteorologieal early-warning estimation map, then according to actual atmospheric precipitation of the area to judge hazard possibility, work out geological hazard early warning and take effective controlling measures to minimize possible losses.
