生态农业是建设社会主义新农村的题中之义,其中包含的生态伦理思想值得认真挖掘。不仅生态伦理的内涵蕴涵在生态农业的含义中,在生态农业的特点中也体现着生态伦理的本质,而且丰富的生态伦理思想还表现在世界生态农业的发展趋势中。生态伦理思想在生态农业不同方面的表现是有差异的。研究生态农业中的生态伦理思想,对我国生态农业的发展具有重要的作用和深远的影响,这些影响和作用,主要又体现在生态伦理思想能够推动生态农业的进一步发展等方面。 相似文献

发展生态农业是我市生态示范区建设的突破口和重要内容。发展生态农业的关键在于协调好生态效益与经济效益的本质关系。在市场经济条件下 ,只有当有利于生态效益提高的产品生产其能够提供足够高的经济效益时 ,生产者才会进行生产 ,从而能同时改善环境。否则就会排斥这种生产 ,恶化生态环境。生态效益与经济效益两者之间的这种既对立又统一的关系 ,使我市在实现从传统农业向生态农业的转换过程中 ,首先必须采取有效措施提高农业生产的经济效益 ,以造就发展生态农业的主体基础。同时要加快市场体系建设 ,加强宣传教育 ,完善补偿机制 ,为我市生态农业发展创造一个良好的整体环境 ,实现我市经济快速发展 相似文献

一、生态农业生态农业是以生态学理论为指导,运用系统工程方法,以合理利用农业自然资源和建立良好的、不同类型的、多层次的农业生态系统为途径,获得生态效益、经济效益、社会效益相统一的综合性效益,是因地制宜地规划、组织和进行农业生产的一种农业发展模式。在每种类型的生态农业系统中,环境要素与生物生产者之间形成互相关联、互相协调的有机体,实现物质与能量在各个生产层次中的循环,并通过合理的投入,获得必要的产出,并维持生产系统的稳定。生态农业具有降低能耗、改善环境及农产品质量、保护自然资源、经济效益高的特点。生态农业的主要途径是通过提高太阳能的利用率、生物能的转化率、废弃物的再循环利用率等,促进物质在农业生态系统内部的循环利用、生态环境保护及获取较高的经济效益,使农业生产处于良性循环中,并可得到统一的综合效益。在我国农村,推广和实施各类生态农业模式有重要意义:可以建立良性生态系统,达到农业生产过程清洁化和农产品无害化;增加农民收入、改善农民生活条件、提高生活质量,达到人类社会与自然和谐发展的目的。 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities. 相似文献

During interview with English majors, it was found that a majority of students expressed disappointment with their experience of English literature classes. Students' dislike of learning English literature appears to be the major problem of teaching English literature in China. Reader response approach is a good way to solve this problem. In this paper, I explain the rationale behind the reader response approach, such as its origin, definition, features, assumptions, and strategies. Then I illustrate how reader response approach works as a teaching strategy by presenting several teaching models. At last I evaluate its usefuiness for teachers and present the advantages of reader response approach in Chinese context. 相似文献
