A Comprehensive Study On Ecological Security In Centralized And Poverty-Stricken Areas

Since the Communist Party of China held the 18th National Congress of the Communist Party of China. The central government leaders continue to strengthen the concept of "green GDP". Earnestly promote the work of ecological and environmental protection. Emphasizing the importance of environmental protection and improving people's livelihood in government work. Different from the previous unilateral pursuit of economic growth style, now the government has a lot of work at work, not only pay attention to economic and pay more attention to the natural environment and the improvement of residents' lives which in the process of economic development.Ecology affects the economy and people's livelihood, and vice versa, once the ecological problems appear to a certain extent, will be anti-bite economic development results, reduce the quality of life of residents. Therefore, in the poverty-stricken areas to carry out poverty alleviation work at the same time must take full account of the economic development and possible environmental problems.The National Poverty Alleviation and Development Office launched a concept of zoning in poverty-stricken areas in 2011. According to the natural conditions,development status, the degree of poverty to implement the relevant precision poverty alleviation policy. Compared with the regional resources and environmental conditions can be found in these areas and China's ecological sensitive area highly coincident.Some areas of the ecosystem have been destroyed almost impossible to recover.Unreasonable poverty alleviation and development work will cause irreversible damage to the natural environment of the poverty zone. The comprehensive evaluation and analysis of the ecological security of the poverty-stricken areas can judge the ecological situation of the poverty-stricken areas at different stages of development and analyze the causes of the changes. Under the premise of understanding the ecological security comprehensive, stress, state and response index of different years. And then the ecological security comprehensive index and the relevant poverty data coupling analysis. Then explore the impact of government poverty alleviation and development work on the ecological environment of poverty-stricken areas. And then provide scientific reference and guidance for the next accurate poverty alleviation and development work.Sanjiangyuan Nature Reserve is located in Qinghai Province and has cold weather,poor soil,high altitude large gap and low population density and a large number of ethnic minorities. In recent years, the state of poverty alleviation and development efforts have been increasing,such as a lot of support in the medical,health,education areas. Which on the one hand made some results on the other hand on the local ecological ring also caused some impact. This paper established the ecological security evaluation system of Sanjiangyuan poverty area based on the PSR framework model.Then coupling analysis the ecological security comprehensive index and per capita net income of farmers, the incidence of poverty, concluded as follow:(1) From 2005 to 2013, eight years, the trend of Sanjiangyuan poverty zone ecological security comprehensive index, pressure index, state index, response index is increased and then decreased, the overall increase. In 2005, the index of ecological security in the study area was above average. In 2010, the index of ecological security in the study area dropped to below the middle level. In 2013, the index of ecological security in the study area increased sharply to a safe level.(2) According to the ecological security trend of Sanjiangyuan poverty area can be analyzed, in the absence of large-scale development due to less traces of economic construction and better maintain the relative to the original natural environment.Therefore, the level of ecological security in the middle. The ecosystem is basically working well. At the beginning of the construction of a larger economic coverage due ignore the devastating impact on the ecological environment which caused by the low status of relevant ecological index. The ecosystem is not working properly. Ecological security at a poor level. After realizing the serious consequences for the environment,the government began to change the mode of economic development, make the improve people's living standards, protect the ecological environment into the regional development goals. Pollution is controlled and the ecological environment has a certain degree of recovery trend. At this point the ecological security at a higher level of safety.(3) There were significant differences in ecological security between counties which reflected the dynamic changes in the range and the same period during the county index differences. Where the natural conditions are better, their ecological security is generally at a moderate or partial level. Natural conditions of poor areas of agriculture,are ecologically sensitive areas, the environment vulnerable to damage. Ecological security is vulnerable and at a low level. In some areas the tertiary industry developed,the level of urbanization is higher, the economic level is relatively high. The index of ecological safety related fluctuates greatly, the late eco-safety index rose faster.Indicating that a certain economic base has a very important role in maintaining ecological security.(4) According to the coupling condition, there was a positive correlation between the comprehensive index of ecological security and the per capita net income of farmers in the study area in 2013. And there was no significant correlation between the comprehensive index of ecological security and the incidence of poverty.
