基于承载力的矿区生态经济系统演化分析 总被引:2,自引:0,他引:2
矿区生态承栽力和生态弹性力与矿区生态经济系统演化密切相关。分析了矿区生态承栽力和矿区生态弹性力的内涵,以矿区生态承栽力、生态弹性力作为矿区生态系统的状态因子,矿区资源经济开发活动强度、资源经济开发速度作为矿区经济系统的状态因子,建立矿区生态经济系统演化的动力学模型。对环境资源掠夺性经济开发、环境保护性经济开发两种开发方式进行计算机模拟,结果显示人类经济开发活动方式对矿区生态经济系统演化趋势具有重要影响,并提出应用技术手段、经济手段和社会手段对矿区生态经济演化系统进行调控。 相似文献

复合生态系统自组织特征分析 总被引:4,自引:0,他引:4
自组织的生态自然观,是根据自然科学提供的事实材料进行概括、提升到哲学层次的一种生态哲学观点。复合生态系统自组织特征包括:动态演化特征、非线性特征、自反馈特征、循环再生特征、协同共生特征。动态演化是复合生态系统自组织有序之源。非线性是复合生态系统自组织的内在动因。自反馈是复合生态系统自组织运行的基本方法。循环再生是复合生态系统自组织运行的可靠保证。协同共生是复合生态系统自组织运行的必然要求。 相似文献

整个生命界是大自然千百万年不断演化发展的成果,在宇宙中十分罕见,而人类的产生和发展使得大自然中生态系统的演化由自在走向自觉成为可能;自觉生态系统的关键性要素是人;生态系统各要素之间的和谐关系,特别是人类与自然的和谐,是人类谋求的生态文明的实质内容;有利于人类的现时和长远的生存发展,是自觉生态的基本功能特征。人类的经济、政治、社会文化以及思想观念的“生态化”是新式的生态文明的保障。 相似文献

国土整治或某一地区的开发利用,都必须应用人工生态系统的理论及思想方法,研究各项具体问题及各问题间的联系,并制定确实可行的发展规划,才能充分发挥人的主观能动作用,调控和建设良好的生态系统。 太湖流域是一个复杂的区域性人工生态系统,它包括很多子系统,如农田生态、湖泊生态、城镇生态和经济生态等。这些子系统都是相互联系的。所以,研究太湖地区的发展,必 相似文献

The paper is about negotiating with issues that discourage innovation. The subject is environmental deterioration, with concern directed at the impediments that keep it from being innovatively resolved. The paper is organized around three issues. (1) The dominant model of environmental concern, called environmental protection, is managed predominantly via command and control approaches. (2) Command and control, by relying on analytical segmentation to subdivide the problem into digestible bits and using formal legislation to direct it, are not up to emerging challenges in the area. (3) More robust models are available but difficult to experiment with due to impediments that discourage change. These impediments are seen in ideals associated with protection, prevention, recycling, and sustainability that tend to do more to sustain harmful practices than to seek beneficial alternatives. Being able to appreciate the underlying restrictions of entropy could help stimulate a more innovative agenda. These issues are tested via a project funded by the EPA entitled ENERGY STAR Homes. 相似文献
