- 摘要:
- 台湾地质构造复杂且断层带多，终年不断之地震促使地层破裂，高温多雨导致风化容易，位於西太平洋台风路径上常遭台风侵袭……此诸因素使台湾潜藏崩坍之可能性。而位居台湾政经中心之台北市，更在经济发展、产业密集、人口稠密之条件下，对山坡地保护区造成极大之开发压力。然因属盆地地形，其四周山坡地着遭不当或过度开发利用，常致水患、崩灾，使市民之生命财产与公共设施安全饱受威胁。山坡地潜在崩坍地区之划定并于禁止不法开发乃成当务之急。本研究系依台北市信义区山坡地之地形、地质、土壤、植生、水文、人文环境、土地利用等因素以地理资讯系统软体ARC/INFO就此诸因素之相关数化图层，依各因素影响崩坍之程度给予不同之极度并进行套叠分析，所得成果有：（1）完成各种崩坍潜在因素之数位主题图。（2）完成各因素整合所得之潜在崩坍危险区划分结果图。（3）潜在崩坍危险区划分之数位图均为实际之大地座标，此可用於未来在本区内有关地理资讯之查询。（4）划定后各区之管理方式建议采取：1、绝对危险区：不管任何理由均应绝对禁止开发利用。2、危险区：以不开发为原则，若遇申请开发则宜慎审其水上保持计划书。3、潜在危险区：可开发，惟应禁止有触发产生危险性质之开发型式与方？
- Abstract:
- The geological structure is so complicated that there are numerous fault zones in Taiwan, frequent earthquake makes the geological structure fragile, high temperature and enough rainfall make weather easily, often suffer from typhoon because it locates on the route of West Atlantic typhoon, those factors above increase the potential landslide in Taiwan.In addition, Taipei city is the political and economic center of Taiwan, the econnmic development is so prosperous, the enterprises and the population are so dense that the protection of the hillslope land around it is under great cultivation pressure.Owing to be a basin, if the hillslope land around it is not properly cultivated or over-cultivated, it often cause floods and landslides.The citizens’ properties and "tilttes are greatly threatened.Apparently, the delineation of potential landslide regions becomes the most important issue.We chose those factors such as totography, geology, soil, plantation.hydrology, human environment, and landuse to analyze and use GIS software ARC/INFO to creater reative cot.erage of those factors in this research and use them to do overlay analysis according to the weights of those factors.The results are:1.we made various kinds of thematic maps’ from potential landslide factors.2.we made an integrated result map of delineation of potential landslide regions.3.the result map use geodetic reference system, so that it is easy to inquire any geographical information in this area.4.We suggest that it would be good to manage those delineated areas if we classify them into the following four categories: (1) Absolutely dangerous area: must prohibit any kind of cultivation without any reason. (2) Dangerous area: no cultivation in principle, and if it is badly necessary, we must check the soil and water conservation proposal closely. (3) Potential dangerous area: must prohibit any type or any form of cultivation that may cause danger. (4) Safe are a:when there is a applying case that will cultivate within the safe areas, we have better make a closely field suveying so that we can avoid the danger of its downstream areas that may caused from the unproper cultivation sensitive hillslope land area.We can also avoid the disasters and unfortunes.
