- 摘要:
- 为了进一步研究吴起县农业生态经济系统耦合态势演变的内在驱动机制，利用吴起县统计年鉴（1990年、1999-2006年）数据，运用主成分分析方法对其进行了分析。结果表明：人为经济发展因素是农业生态经济系统演变的主要驱动力（贡献率为72.849 9%），人口压力驱动因子次之（贡献率为11.569 5%），而自然生态环境是影响吴起县农业生态经济系统耦合过程的基础（贡献率为8.168 1%）。针对目前吴起县农业生态经济系统耦合的内在驱动机制及其面临的问题，提出调整产业结构、发展林草及其相关产业链等措施来保证农业生态经济系统的稳定。
- Abstract:
- In order to further research the inner drive coupling mechanism of agricultural eco-economic system, the drive force is analyzed by using the statistical date of Wuqi county (1990, 1999-2006) and principal components analysis method. The results showed that the human economy development factor is the main driving force of agricultural eco-economic system evolution (contribution rate is 72.849 9%) and the population pressure is the second driving factor (contribution rate is 11.569 5%). The factor of natural ecological environment is the basis of coupling process of agricultural eco-economic system in Wuqi county (contribution rate is 8.168 1%). Aiming at the internal driving mechanism and its facing problem of agricultural eco-economic system. The county need to adjust the industrial structure, develop grass industry to ensure the stability of the agricultural eco-economic system.
