“生态学”概念的嬗变及生态文明建设的内涵与实质——兼谈澳大利亚生态文明与社会和谐的几个视点
Conceptual Evolution of “Ecology” and Essence of Eco-Civilization Construction——With a Personal Look at the Eco-Civilization and Social Harmony in Australia

International Journal of Ecology (IJE) , 2014, DOI: 10.12677/IJE.2014.31003
Abstract:
基于对“生态学”概念基本内涵的理解,笔者认为生态学研究与应用的主要目标之一是生态调控,而生态调控是指“使生命系统内部协同,以及使生命系统整体与环境调适的行为”。这样,自然生态的维护、政治生态的协和、个人与社会生态的协调都可归结为“生态作为”或“生态关系的调整”。生态关系是指生命系统与环境系统之间的复杂关系,当然也包括生命系统内部的各种关系。生命系统具有多样性和层级性、暂稳性和自演性、整合性和非线性;环境系统具有多样性和多元性、扩展性和随机性、复杂性和非线性。环境系统因子的数量和质量都会随着生命系统内含的变化而变化,因此生态调控方式、方法也必然多种多样,可以不断综合与优化,产生越来越好的行为效果,但若作为不当,也会适得其反,即使是细小的不良作为,也可能会极度放大,产生极度恶劣的效应。生态文明是指生态思想与方法贯穿于人类生产与生活的各个方面,也即人类习惯于用生态学的原理与方法思考和处置生产与生活中的实际问题,以实现可持续发展与社会和谐。没有全球性共同的“生态作为”,也不会有全球性的生态安全、社会稳定与和谐发展。生态文明建设的实质就是“生态作为”的自觉、规范与实施过程。基于一年的访学经历,笔者把政治、教育、社交、环保、城建和交通作为视点对澳大利亚的生态文明与社会和谐进行了点滴简介,同时注意到,中国正处于建设具有自身特色的社会主义初级阶段,就像初升的太阳,前景无限美好!中国特色社会主义制度的优越性已令澳人震惊,近年澳洲“汉语和中国文化热”的兴起就是澳人渴望了解或通晓中国的集中体现。的确,人类需要不断地学习和进步,需要更多更好地了解自然、自身和他人,人类每上一个台阶,都会感觉到自己更加渺小,都会更加深切地体会到个人与大自然及社会和谐之奥妙,从而更加自觉努力地去促进这种和谐的生产与生活。然而,如何兼收并蓄,将中国优秀的传统文化与西方现代科技文化有机融合,构建具有中国特色的生态文化,自觉、规范化、创造性地“生态作为”,以全面推进我国的生态文明建设与社会和谐仍然是需要系统深入研究的课题。
Based on the discussion about the conceptual evolution of “Ecology”, this paper argues that the main aim of ecological research and application is “Ecological regulation and control”, which means the behaviors to make life-system inwardly-synergying while the entirety of life-system overall-adapting to its environments. So the conserving of natural ecosystems, the harmonizing of various political relationships, and the reconciling of social individuals per se and their social-eco-environment all may come down to “adjusting of eco-relationships” or “eco-doings”. Eco-relationships mean the complex connections between life-systems and their environment-systems, surely including internal ones of life-systems. Life-systems are of diversity and hierarchy, temporary-stability and self-evolutioning, conformability and nonlinearity while environment- systems are of diversity and multi-elementity, extensibility and stochasticity, complexity and nonlinearity. The quantities and qualities of environment-systems factors vary from the contents of life-systems, therefore, the ways and methods of “Ecological regulation and control” certainly are diversified, may continuously integrate and optimize to produce better and better doing-effects. However, if our doings are wrong, we will just see the opposite to what we wish, and even if there are some trivial wrong-doings, they may be extremely amplified and resulting in exceeding abominable effects. Eco-civilization implicates that

Abstract:
在我国的制度背景下,国有经济占相当大的比重。政府主导的市场经济改革决定了我国特有的经济“双轨制”,最终决定了上市公司受不同实际控制人的影响。随着现代企业制度的不断发展,两权分离导致公司治理问题日益突显。本文以2007~2013年中国A股上市公司为研究样本,首先实证分析了政府控制、公司治理结构对企业避税的影响,然后根据实际控制人性质将上市公司细分为中央政府、省级政府、市级政府、县级政府及非政府控制五种类型,研究不同政府层级控制对避税的影响作用,并对比分析了不同实际控制人下公司治理对避税行为的影响效应。研究发现:相比非政府控制的企业,政府控制的企业避税行为更加保守,尤其是中央政府和省级政府控制的企业。监事会有效的监管可以抑制企业避税行为,股权集中度对避税是正向作用。本文的分析为深入探讨政府控制、公司治理与企业避税的关系提供新视角。
Under the background of Chinese special system, state-owned economy accounts for a large proportion. The market economy reform led by the government determines our unique dual-track economy system, and it finally determines that listed companies are subject to dif-ferent actual controllers. With the ever-developed modern enterprise system, the separation of ownership and management right leads to corporate governance issue increasingly prominent. Using Chinese listed companies during 2007-2013, this paper firstly studies the influence of government control, corporate governance on tax avoidance behavior and then divides the listed companies into five kinds according to their controlling characteristic: cen-tral-government controlling, province- government controlling, city-government controlling, county-government controlling and non- government controlling and empirically analyses the impact on tax avoidance of different government-levels controlling. The results suggest that compared to non-government controlled companies, the tax avoidance behavior of government controlled companies are less aggressive, especially central-government and prov-ince-government controlled companies. Effective regulation of board of supervisors can reduce corporate tax avoidance and ownership concentration has a positive effect on tax avoidance. This paper provides new perspectives for further analyzing the relationship between govern-ment control, corporate governance and tax avoidance.

In this paper, through analyzing the engineering and technical personnel needs of petroleum enter- prise, four types of professional and technical personnel of petroleum enterprises are in urgent need, consid- ering the training status of the fulltime postgraduates with professional degree. By analyzing the training tar- get of engineering and technical personnel in petroleum enterprises for petroleum colleges and universities, qualities of petroleum engineers are studied. Those professional degrees graduate education for oil and gas engineering become the cradle for the birth and the growth of petroleum engineers is specified; and that the oil companies demand for other types of talent should be cultivated by other types of students. Postgraduate education programs of oil and gas engineering are studied out based on the above-mentioned contents. Four major training modes of petroleum engineering are explored. Through exploration and summary of pro- fessional degrees graduate trainings for oil and gas engineering, desirable experiences of different types of postgraduate training and different social demand for talent can be obtained.

基于花粉萌发与结铃表现选育耐高温高产杂交棉

湖南农业大学学报(自然科学版) , 2010,
Abstract: 2004年以苏棉12号、中棉12号、苏棉16号和J011为母本,分别与新优棉68和K-79配制了8个杂交组合.2005—2006年对配制的棉花杂交组合在盛花期和结铃期的单株结铃数、成铃率及其花粉在室内培养时最高萌发率和花粉管最长生长长度进行了测定,并进行了主成分分析,根据第一和第二主分量 (PC1和PC2)值,可以将杂交组合划分为耐高温(+PC1,+PC2)、较耐高温(+PC1,-PC2)、较敏感(-PC1,+PC2)和敏感(-PC1,-PC2)类型.从配制的8个杂交组合中筛选出来的耐高温组合JL06在区域试验中表现出结铃性好、适应性强和高产的特点,并于2009年3月通过了湖南省作物品种审定委员会的审定.采用该方法,能够将耐高温性状引入育种目标,培育出耐高温和高产的棉花品种,以适应当前的植棉环境和将来变暖的气候条件.
