Scenic Landscape Value Assessment And The Theory Of Landscape Protection And Reconstruction In The Geological Disaster Prevention

Thesis through countless document investigation and on-site investigation, research and analysis, knot and expert consultation and the relevant local socio-economic development needs, Refining landscape connotation, select landscape evaluation index of scenic spot from the natural and cultural aspects ,using ecological principles of natural and cultural landscapes, from the landscape aesthetic values, social effects, landscape quality, the establishment of three aspects of the system to complete the assessment of landscape value of scenic spot index system. Thesis selected 3 criterion layer, 11 first grade indexes, 33 secondary indexes, 99 third grade indexes (a total of 147 evaluation indexes ) to establish a scientific, reasonable and feasible value of landscape evaluation system.Thesis analyzed the method of which be used in the evaluation of landscape,making sure adopting the method of Fuzzy comprehensive evaluation, based on the Analytic Hierarchy Process(AHP) to evaluating the value of landscape. By investigated the different scenic spot,relative weights of different index are confirmed.Based on the theory of fuzzy mathematics,multi-object multi-hiberarchy fuzzymatics assessment model of landscape index is built, and the final assessment results are expressed with score computed by this way.Being compared with qualitative analysis of the traditional,the qualitative and quantitative method mentioned in the paper improve objectivity and scientific nature. This evaluation system and evaluation model is applied to Jinfo Scenic Area and the Yangtze River Three Gorges scenic area landscape value assessment, evaluation results on the actual match, effect is good. This evaluation system and evaluation model is applied to Jinfo Scenic Area and the Yangtze River Three Gorges scenic area landscape value assessment, evaluation results on the actual match, effect is good. This system and the model also applies to other scenic areas of landscape value assessment. The conclusions can be applied to scenic landscape planning, design, protection, etc, and with some reference and guidance.In this paper,examples of scenic spots, from the three aspects of landscape aesthetic values, social effects, landscape quality, detail geological disasters on the value of landscape impact. Jinfo scenic areas for instance, an outbreak of geological disasters by their scores before and after the landscape value of the comparative calculations,and the result could quantify the value of geological disasters in the impact on the landscape.Thesis follow the landscape protection, reconstruction and value-added principle ,and conduct geological disaster prevention in the landscape protection and reconstruction of the theory to construct a the landscape model of urban renewal in geological disaster prevention. Geological disaster prevention engineering and landscape protection and construction should be an organic combination of, arising traces to a minimum of disaster management project, to achieve the ecological improvement and environmental coordination to achieve the protection of the landscape.
