摘要
【目的】自然与社会生态的高度协调是生态恢复的保证,探索侵蚀环境生态恢复过程中自然和社会生态的协同耦合关系,为流域生态恢复提供理论依据。【方法】以典型侵蚀环境小流域——纸房沟流域为例,通过收集资料、测试分析,选择不同社会人文环境因子和自然环境因子,运用统计和相关分析等方法,研究生态恢复过程中自然与社会生态的协同效应。【结果】在生态恢复过程中,表征流域生态状况的因子植被覆盖率、土壤有机质含量和粮食单产潜势实现率与表征社会经济人文的因子人均纯收入、恩格尔系数、人均基本农田、义务教育普及率、水土流失治理度和工副业贡献率之间关系密切,表现出较好的协调性效应,生态状况的改善能促进社会经济的发展,同样,社会经济的发展亦能推动生态环境的恢复。同时,体现流域系统稳定性的生态综合功能的系统抗逆力与其社会经济人文状况也有密切关系,系统抗逆力增强,流域稳定性提高可促进社会经济人文状况的好转。同样,流域社会经济人文状况的好转亦可推动其生态功能的发挥,即系统抗逆力的增大,使流域系统稳定性增强,表现为较好的协调效应。此外,国家政策策略对生态恢复具有重要的导向作用。【结论】侵蚀环境小流域生态恢复过程中自然与社会生态具有较强的协同互作效应关系,自然生态恢复促进社会生态发展,同样社会生态发展促使自然生态恢复。
Abstract： [ Objective ] The high synergy between nature and society eco-system is a guarantee of ecological restoration. The coupled relation between nature and social ecology in the process of ecology recovery under the erosion environment were studied to provide scientific foundation for restoring ecology of small watershed. [Method] The research taken Zhifanggou small watershed of typical erosion environment as study plot, selected social-environment state effect factor and natural-environment factor and studied the synergistic effect on the process of restoration. [ Result ] The results indicated that the factors representing ecological conditions tied up with the factors standed for social-econonmic state, The ecological condition improvement can promote the development of social economy and the development of social economy also can accelerate the restoration of the healthy eco-environment, At the same time, the system adverse resistance reflecting the stability of watershed eco-system is affiliated with social-econonmic state. In other words, the higher the amplification of system adverse resistance is, the better the social-economic state condition is. And the counterpart is right. In addition, national policy influenced ecology restoration orientedly. There were preferable synergistic correlation between nature and social ecology in the process of ecological recovery under the erosion environment. [Conclusion] Thedevelopment of social eclogy is promoted by natural ecology.At the same time,thedevelopment of natural ecology is promoted by social ecology.
