ABSTRACT
Eco-tourism risk refers to the entire ecosystem or threatened ecological landscape features outside, thereby reduces certain elements within the system or their own health, productivity and genetic structure. Eco-tourism refers to the risk analysis of eco-tourism by one or more stress factors to assess their possible line. The reason for the ecological risk analysis is to be the negative eect of a scientific evaluation of environmental damage caused, and thus provide a scientific basis for the eco-tourism system. From the current perspective, ecological risk is ecology or environmental chemistry and risk-based on science and other disciplines, the main research about ecology issues. From the current point of view, the risks can be divided into ecological risk caused by biological engineering, and by the invasion, etc. Some scholars and experts have analyzed the ecological risks, got receptor analysis, hazard
assessment and risk characterization. The mean of the receptor assay is determined by both qualitative or quantitative methods to determine, analyze, the system will be analyzed in the key eco-tourism species, communities and populations, the selection of appropriate risk receptors, the risk of the entire eco-tourism final reaction system, implementation analysis, calculation and grasp of objectives. The hazard assessment is the use of eco-pathology of various toxicity tests to analyze indicators and determine the likelihood of risk. Risk analysis of eco-tourism, coupled with the complexity of the ecosystem is able to determine the receptor, the wind vector characterization and non-deterministic processing, and ultimately determine the ecological risks.
