Abstract

Huangshan Scenic Area is the world's natural and cultural heritage and the world geological park, after the reform and opening up, the rapid development of tourism, the number of tourists in the region of 104,300 people in 1979, into the mountains number has reached about 2.4 million people. Overload an increasing number of tourists and the increasing tourism development activities, coupled with the region's flood, drought, landslides, mudslides and other natural disasters from time to time, so that the original habitat while facing the threat of tourism and non-tourism in the region. Scenic ecological environment in good condition, but the tourist scenic spot is a piece of both the value and vulnerability of the area, once the ecological risk source outbreak in Huangshan Scenic Area, the natural landscape of Huangshan will cause huge and irreversible disaster. Therefore, how in the development process to achieve full and effective protection of the scenic Cheng to be studied in depth. Ecological risk assessment is the theoretical basis guiding the Huangshan Scenic economic and ecological environment coordinated development. In this study, the basic theory of ecological risk assessment, ecological risk assessment theory and tourism discipline, theory of mountain scenic resort ecological risk analysis and evaluation. Select on the basis of the evaluation of the ecological risk factor status quo of the main ecological risk source and gain a systematic analysis, build the Huangshan Scenic ecological risk assessment model, and finally proposes the Huangshan Scenic ecological risk management system. The main results are as follows: In theory, the paper first analyzes the content and progress in research of ecological risk assessment, and discusses the ecological risk assessment of the tourist area. This study referenced the double evaluation model is especially for tourist scenic areas with tourism as the main function of such a region build. The model in theory risk stress analysis research scenic two levels of tourism and non-tourism \In the empirical to the theoretical research as a guide to empirical study of Huangshan Mountain. Ecological environment evaluation method combined with GIS technology to the area to carry out a risk assessment, which aims to provide theoretical and technical support for regional ecological risk management. Has important practical significance for improving the scenic ecological environment and promote sustainable development. In this paper, the use of topographic maps, land use maps combined with field research on the basis of established ecological risk receptors and statistics of landscape structure as ecological risk assessment services. First through a comprehensive bibliographic information and site visits, summed up the study area, various ecological risk factor ecological risk caused by pressure. Come to Huangshan Scenic Area Ecological Risk Sources the the tourism ecological risk source and non-tourism ecological risk source categories, tourism ecological risk source is the development and construction of the scenic spots, tourism services, tourists and other ecological risk source; non-tourism eco- sources of risk, including flood and drought disasters, high winds, lightning, extreme temperatures, landslide, biological invasions, forest fire danger, urbanization construction. Huangshan Scenic various sources of risk to analyze this double risk model. Then through field investigation and consulting experts, a comprehensive analysis of the ecological risk factor intensity, range size, the size of the intensity of the impact on the ecosystem. Established ecological risk source: the four major categories of ecological risk of floods, biological sources of risk, forest fire danger and tourism disturbance. For four major ecological risk source with a special evaluation of its cause adverse effects were characterized to analyze the these four ecological risk source receptor interference and hazards. Risk source GIS overlay a risk plaque, a 2384 internal sources of risk and ecosystem has a homogeneous risk area. Based on the specific circumstances of scenic, ecological flexibility index to reflect the different ecosystems strength to withstand adversity; application fragmentation index to reflect the degree of interference of different ecosystems; vulnerability index to reflect the vulnerability of different ecosystems. With the ecological elastic Index, the product of three factors of the fragmentation index and the vulnerability index to reflect the degree of ecological damage, combined ecological risk probability comprehensive evaluation of the Huangshan Scenic ecological risk. Comprehensive calculation of the ecological risk and GIS overlay, Huangshan Scenic Area ecological risk grading chart. The ecological risk classification chart area is divided into four ecological risk area. High-risk areas are mainly located in Spa Management District the Jade Screen Management District, in some areas of the eastern management area and the Cloud Valley management area; higher risk areas are mainly located in the Pine Valley area and the North Sea management area; lower risk areas are mainly located in the Pine Valley Management District the western and northern regions of the north, in most areas of the Fishing Bridge Management District and floating Creek Management Area, was semi-circular ring-shaped distribution; low-risk areas are mainly distributed in the floating Creek Management Area, Spa Management District and the southern part of the Cloud Valley Management District, the peripheral part of the essence of Huangshan scenic. The outcomes of the scenic Ecological Risk Assessment and ecological protection, with reference to the relevant ecological risk management case, put forward the Huangshan Scenic ecological risk management goals, principles and methods. On this basis, the actual situation of the scenic and research methods, risk management countermeasures. In order to achieve the coordination of the ecological environment, effectively protect the Huangshan Scenic biodiversity and ecosystem structure and function stability, to achieve as much as possible by reducing unnecessary ecological risk, save the possible loss, improve the safety factor of the scenic tourist, to provide a theoretical basis for the sustainable development of the Huangshan tourism.
