【摘要】：基于驱动力—状态—响应(DSR)模型,从生态视角提出了减贫指数测度指标体系并运用BP神经网络进行测度,再通过脱钩分析探讨了三峡库区的生态环境与社会经济之间的发展关系,最后运用GIS分析了三峡库区综合减贫压力的时间规律及空间分布。研究发现:(1)2007—2013年间,三峡库区扶贫压力在减轻的同时,76%的区县社会经济发展以超速的生态破坏为代价;(2)库首地区的综合减贫指数东高西低,呈现两极分化趋势;(3)库中地区贫困"塌陷",形成库区"发展分散,贫困集聚"的局面;(4)库尾呈现"生态—经济恶性循环"趋势。基于以上研究发现,从生态视角出发提出了旨在改善库区贫困问题的对策建议。
[Abstract]:Based on the driving-state-response DSRmodel, the index system of poverty reduction index is put forward from the ecological point of view, and BP neural network is used to measure it. The development relationship between ecological environment and social economy in the three Gorges Reservoir area is discussed through decoupling analysis. Finally, the time law and spatial distribution of the comprehensive poverty reduction pressure in the three Gorges Reservoir area are analyzed by using GIS. The study found that from 2007 to 2013, the poverty alleviation pressure in the three Gorges Reservoir area was alleviated, while the socio-economic development of 76 percent of the districts and counties was at the cost of excessive ecological damage.) the comprehensive poverty reduction index in the first part of the reservoir area was low in the east, high and west. In the reservoir area, poverty "collapses", forming the situation of "scattered development and agglomeration of poverty" in the reservoir area. 4) the end of the reservoir presents a "vicious circle of ecology and economy". Based on the above findings, the countermeasures and suggestions to improve poverty in the reservoir area are put forward from the ecological point of view.
