【摘要】：在众多地质灾害之中,泥石流灾害属于影响大、极具破坏力,且不容忽视的重大灾害之一。由于我国的地理环境决定了在全国许多地方都将存在泥石流灾害威胁。尽管国家对于泥石流灾害已有了足够的重视,也投入了大量的人力物力进行防治,但是防治效果并不都能取得明显的成效,甚至有的时候还会出现投入产出比为负的情况。本文参考了国内外研究资料,又进行了现场调研工作,利用将定性和定量相融合的研究方式,对赵庄泥石流灾害类型、规模、活动特征以及受灾范围等方面做了比较详尽的分析,对研究区泥石流灾害进行危险性评估。从而,构建出泥石流灾害防治工程效益评价模型。本模型从两个层面着手进行构建,即:经济效益评价以及社会效益评价。首先通过经济效益评价模型,计算出研究区潜在的经济损失评价值;然后以“投入成本”、“施工技术”、“防治效果”、“社会影响”作为评价模型的评价指标,从两个备选防治方案中优选出一个最佳方案;再从投入产出比的角度,将研究区潜在的经济损失评价值与投入成本作比较后,这样就对赵庄泥石流灾害防治工程做出了经济效益评价。接着选取“可持续发展效果”以及“生态环境影响”作为社会效益评价的两个评价指标,从而对研究区进行社会效益评价。本文的研究主旨在于能够建立一个科学的评价模型,从而能在泥石流灾害防治方面提供正确的研究思路。希望以此能对我国将来在泥石流灾害防治方面的发展有所帮助,对创造更安定、更和谐的社会环境起到促进作用。
[Abstract]:Among the many geological disasters, debris flow is one of the most important disasters which have great influence and destructive power.Because of the geographical environment of our country, there will be debris flow disaster threat in many parts of the country.Although the country has paid enough attention to the debris flow disaster and invested a lot of manpower and material resources to prevent and cure, but not all of the control effects can achieve obvious results, even sometimes there will be a negative input-output ratio.In this paper, referring to the domestic and foreign research materials, the field investigation work is carried out, and the types and scale of debris flow disasters in Zhaozhuang are analyzed by combining qualitative and quantitative research methods.The characteristics of activity and the scope of disaster are analyzed in detail, and the hazard assessment of debris flow in the study area is carried out.Thus, the benefit evaluation model of debris flow disaster prevention and control project is constructed.This model is constructed from two aspects: economic benefit evaluation and social benefit evaluation.The evaluation value of potential economic loss in the study area is calculated through the economic benefit evaluation model, and the evaluation indexes are "input cost", "construction technology", "prevention and control effect" and "social impact".The best one is selected from the two control options, and the potential economic loss evaluation value of the study area is compared with the input cost from the angle of input-output ratio.In this way, the economic benefits of the Zhaozhuang debris flow disaster prevention project are evaluated.Then "the effect of sustainable development" and "the impact of ecological environment" are selected as two evaluation indexes of social benefit evaluation, so as to evaluate the social benefits of the study area.The main purpose of this paper is to establish a scientific evaluation model, so as to provide a correct research idea for debris flow disaster prevention.It is hoped that this will be helpful to the future development of debris flow prevention and control in China and will promote the creation of a more stable and harmonious social environment.
