陕西省社会发展对生态压力的脉冲响应分析研究

为了应对全球性的生态危机,了解区域生态安全的影响因素及社会发展对生态压力的作用关系,采用生态足迹法计算了陕西省1991年至2011年的生态足迹、生态承载力及生态压力指数,得出陕西省21年来的生态安全等级发展趋势.建立社会发展状态评价指标体系,运用物元可拓模型关联函数法计算得出各年份陕西省的社会发展状态指数,进而基于脉冲响应分析,研究陕西省社会发展与生态安全的动态关系.结果表明,陕西省社会发展对生态压力的影响呈正向作用,而生态压力对于社会发展呈现负面影响.

Impulse Response Analysis of Social Development to Ecological Pressure in Shaanxi Province

In order to cope with the global ecological crisis and understand factors influencing the regional ecological security and the impact of social development on the ecological pressure ,a study was made to figure out the ecological footprint ,ecological capacity and ecological pressure index of Shaanxi Province from1991 to 2011 by the method of ecological footprint ,with the ecological security level trend of Shaanxi Province in the 21 years obtained .Then a social development state evaluation index system was established .The state index of social development in Shaanxi Province in each year calculated by using of the model of element extension and the method of the correlation function .And then ,based on the impulse response analysis , the dynamic relationship between social development and ecological security in Shaanxi Province was studied .The results show that in Shaanxi Province social development has a positive impact on ecological pressure ,w hile ecological pressure has a negative impact on social development .
