The Construction Of Water Conservancy Scenic Area Ecosystem Risk Assessment And Early Warning Mechanisms

In the social economy development to after certain level, people begin tofocus on their own life of the natural environment change, and people’senvironmental conception change, ecological risk assessment is in thissituation gradually began to rise of a research field. In this paper theecological system of water conservancy scenic spot risk assessment by recentresearch of ecological risk when a new evaluation method: landscapeecological risk assessment. This evaluation method is based on the basis oflandscape types cross the research, mainly through the description naturalecological disasters or human activities on the ecological system of the area,the negative effect and harm and the extent of the harm to express the region’secological risks. Landscape ecological risk assessment method involved whenthe study determined and risk source evaluation receptors in the area havemany differences, this is usually not the ecological risk assessment. In thispaper, according to the ecological risk assessment has now the method, andpay attention to the selection of objects in scale and space have a certaindifference, this paper of risk assessment or use the landscape ecological riskassessment in regional scale of use general steps: in the study area a definition,ecological receptor analysis, area, ecological risk source analysis and hazardanalysis exposure and regional ecological system of comprehensive riskassessment. In addition, the water conservancy scenic spot as a touristdestination, and carry on the ecological risk assessment, it is not onlybeneficial to protection to the study of ecological environment, but also tobuild local industrial structure reasonable, and eventually get the economy,society and environment, harmonious and unified development. So, for aregion ecological risk assessment is a region in the development planningshould be strong concern and carefully before thinking about.In this paper, the theory of ecology ecosystem theory, ecological value deals with the environment assessment study theory as to ecological risk assessment of the theoretical basis, and then based on the south bay water conservancy scenic spot on the current status of scenic spot of landscape type classification, sure seven kinds of ecological risk receptor, namely the thickets, and Succoth shallow grass, Lin ecological conservation areas, water area, farmland, leisure and amusement section and land for construction, comprehensive analysis in the seven risk based on the receptors, and in the south bay water conservancy scenic spot investigation data and have graphics material, through the analysis of the qualitative and quantitative evaluation, determine the south bay water conservancy scenic spot the main ecological risk source for:flood, drought and pollution, analysis to the three kinds of ecological risk source of the south bay water conservancy scenic spot different landscape types of influence degree and range of influence, get different ecological risk level distribution, the last of the south bay water conservancy scenic spot of the comprehensive ecological risk evaluation. Analysis by south bay water conservancy scenic spot ecological risk and risk management, the relation between the final south bay water conservancy scenic spot of ecological early warning mechanism.
