文章以黑龙江省各区县为研究对象,根据2013年相关统计年鉴计算各县域2012年生态足迹、生态承载力、生态赤字和生态压力指数的基础上,应用偏最小二乘回归分析法定量揭示影响各县域生态安全状况的关键社会经济因素。研究结果表明:黑龙江省2012年各市县的人均生态足迹为3.93 km~2/人,人均生态承载力为4.24 km~2/人,人均生态赤字为0.31 km~2/人,生态压力指数为1.89,说明黑龙江省生态安全状况整体较好;但各县域的生态安全状况空间分布极不均衡,整体表现为从北向南、自东而西逐渐变差的格局;区域产业结构、富裕度和基础设施是影响黑龙江省各县域生态安全的重要因素。研究结果可为该地区可持续发展下的产业布局及基础设施规划提供重要参考。
Based on the calculation of the ecological footprint, ecological carrying capacity, ecological deficit and ecological pressure index of all counties in 2012 according to the relevant statistical yearbook in 2013, the article applies partial least-squares regression analysis to quantitatively reveal the impact of The Key Socio - Economic Factors of County Ecological Security. The results showed that the per capita ecological footprint of all cities and counties in Heilongjiang Province in 2012 was 3.93 km ~ 2 / person, the per capita ecological carrying capacity was 4.24 km ~ 2 / person, the per capita ecological deficit was 0.31 km ~ 2 / person, and the ecological pressure index was 1.89 , Indicating that overall ecological security in Heilongjiang Province is good. However, the spatial distribution of ecological security in all counties is extremely uneven. The overall pattern is from north to south, and gradually deteriorates from east to west. Regional industrial structure, affluence and infrastructure Is an important factor that affects the ecological security of all counties in Heilongjiang Province. The results can provide important reference for the industrial layout and infrastructure planning under the sustainable development in this area.
