Study On Methods Of Disaster Prevention And Mitigation To The Southwest Mountain Towns On The Basis Of The Low Level Of Ecological Security Pattern

In the process of rapid advance of urbanization in our country, the economic benefits of rural development has become the focus of social benefit and ecological benefit is weak gradually apparent. This is associated with social and ecological environment problems highlighted. In terms of the environment, environmental degradation, resource depletion, air pollution, water pollution and garbage siege etc. Phenomenon exists generally, increasingly serious ecological environment deterioration, the ecological environment function is decreasing, the low level of ecological security pattern, villages and towns fade out the ability to withstand natural disasters, seriously affected the sustainable development of the village.Focus on the reality of ecological security pattern level is not high and the safety problem is distinctively serious in the mountain towns of our Country. The article starts with the relationship between disaster formations with ecological environment, and then defines the concept of low level of ecological security pattern. Through the investigation of the Southwest Mountainous towns, the basic law of characteristic of mountain towns under low level of ecological security pattern is found out, and the mechanism of it is revealed. Based on these, the article analyzes the inherent relationship between them, and provides method of disaster prevention and mitigation to the mountain towns under the low level of ecological security pattern.Paper mountain villages and towns in China are widespread pattern of ecological security level is not high, the reality of security problems, from the relationship of disaster formation and the ecological environment, defines the concept of low ecological security pattern, and establish its villages and towns in southwest low level evaluation system of ecological security pattern. Based on the investigation to the southwest mountainous villages and towns, and discovered the mountain villages in the low ecological security pattern under the present characteristics of the law, the basis of revealing the rule of mountain town has the characteristics of mechanism, based on analysis of the disasters and low mountain villages and towns the inner link between ecological security pattern, and put forward the mountain villages and towns under the low ecological security pattern of disaster prevention and mitigation countermeasures and methods.
