【摘要】：隨著社會(huì)的進(jìn)步,人類生活水平的提高,城市規(guī)劃建設(shè)規(guī)模的擴(kuò)大以及對(duì)自然開(kāi)采改造工程的增加,地質(zhì)災(zāi)害也頻繁發(fā)生。這影響了人類生產(chǎn)生活,同時(shí)還威脅了人類財(cái)產(chǎn)及生命安全。而今,對(duì)地質(zhì)災(zāi)害的研究與分析也得到了重視。論文選取云南省鎮(zhèn)沅縣為研究區(qū)域,運(yùn)用GIS對(duì)單一因子影響下的滑坡地質(zhì)災(zāi)害敏感性進(jìn)行分析,同時(shí)還對(duì)多因子共同影響下的滑坡地質(zhì)災(zāi)害敏感性、脆弱性、危險(xiǎn)性、風(fēng)險(xiǎn)性進(jìn)行分析。通過(guò)對(duì)各基礎(chǔ)圖層進(jìn)行運(yùn)算、分類、賦值等操作,對(duì)鎮(zhèn)沅縣的滑坡地質(zhì)災(zāi)害進(jìn)行分析。最終得到了滑坡地質(zhì)災(zāi)害危險(xiǎn)性及風(fēng)險(xiǎn)性的分類等級(jí)。同時(shí),針對(duì)所研究的結(jié)果,提出滑坡地質(zhì)災(zāi)害的預(yù)防措施。論文完成的研究工作如下：一、收集相關(guān)資料,介紹了GIS在地質(zhì)災(zāi)害和滑坡災(zāi)害中的國(guó)內(nèi)外發(fā)展現(xiàn)狀,并著重介紹了GIS在滑坡災(zāi)害中的研究。二、結(jié)合GIS技術(shù),提出了論文的研究?jī)?nèi)容和技術(shù)路線,選取了可運(yùn)用至本文研究的GIS的功能,并將操作的基本方法進(jìn)行了介紹。三、收集研究區(qū)自然概況和相關(guān)數(shù)據(jù),運(yùn)用GIS技術(shù)編繪相關(guān)圖件,包括坡度圖、地形起伏度圖、降水分布圖、斷裂帶分布圖、人類工程活動(dòng)情況等基礎(chǔ)圖件。四、采用Logical模型分析并確定研究區(qū)內(nèi)各單一孕災(zāi)環(huán)境因子對(duì)滑坡地質(zhì)災(zāi)害敏感性的影響,建立滑坡地質(zhì)災(zāi)害危險(xiǎn)性、風(fēng)險(xiǎn)性、脆弱性、敏感性評(píng)價(jià)的各專題圖層,形成滑坡地質(zhì)災(zāi)害的評(píng)價(jià)體系。五、運(yùn)用地理信息系統(tǒng)技術(shù)中的空間分析,對(duì)各個(gè)專題圖層進(jìn)行空間疊加分析以及疊加計(jì)算,得到脆弱性、敏感性、危險(xiǎn)性等評(píng)價(jià)指數(shù)。最終依據(jù)滑坡地質(zhì)災(zāi)害的評(píng)價(jià)體系,得出滑坡地質(zhì)災(zāi)害的等級(jí)劃分。
[Abstract]:With the progress of society, the improvement of human living standard, the expansion of urban planning and construction scale and the increase of natural mining and transformation projects, geological disasters also occur frequently, which has affected human production and life. At the same time, it also threatens the safety of human property and life. Now, the research and analysis of geological hazards have also been taken seriously. This paper selects Zhenyuan County of Yunnan Province as the research area. Using GIS to analyze the sensitivity of landslide geological hazard under the influence of single factor, and at the same time, to analyze the sensitivity, vulnerability and risk of landslide geological hazard under the influence of multiple factors. Analysis of risk. Through the operation of each basic layer, classification, assignment and other operations. The landslide geological hazards in Zhenyuan County are analyzed. Finally, the classification grades of landslide geological hazards and risk are obtained. At the same time, according to the results of the study. The prevention measures of landslide geological hazard are put forward. The research work completed in this paper is as follows: 1. Collect relevant data and introduce the development status of GIS in geological hazard and landslide disaster at home and abroad. The research of GIS in landslide disaster is introduced emphatically. Secondly, combining with GIS technology, the research content and technical route of this paper are put forward, and the function of GIS which can be applied to this paper is selected. And the basic operation methods are introduced. Third, collect the natural situation of the study area and related data, using GIS technology to compile related maps, including slope map, topographic relief map, precipitation distribution map. The basic maps of fault zone distribution, human engineering activity and so on. Fourthly, Logical model is used to analyze and determine the influence of each single disaster environmental factor on the sensitivity of landslide geological hazards. To establish each thematic map layer of landslide geological hazard risk risk vulnerability and sensitivity evaluation to form the evaluation system of landslide geological hazard. Fifthly the spatial analysis of GIS technology is used. Based on the spatial superposition analysis and superposition calculation of each thematic layer, the vulnerability, sensitivity, risk and other evaluation indexes are obtained. Finally, the evaluation system of landslide geological hazard is adopted. The classification of landslide geological hazard is obtained.
