美国、英国、日本、意大利、巴西等国先后对本国欠发达地区进行了开发建设。它们以城镇化为动力、大力发展城镇工业，已经取得许多成功经验，也有着深刻的教训。中国西部大开发可从国外开发欠发达地区的经验教训中受到启迪，以城镇化为增长点带动区域经济的全面发展，重视生态环境的保护和建设，加强以交通运输为重点的城镇基础设施建设，探索出西部地区城镇工业独特的发展道路，实现经济、社会和环境的可持续发展。 相似文献

湖南省青山硫铁矿矿体形态较复杂 ,区内构造以断裂为主 ,溶洞发育。采用多层矿体房柱法开采 ,采矿顺序从上而下 ,由矿体两翼向轴部回采 ,使得井下围岩应力逐步向中央轴部集中 ,引起地压活动 ,导致坍塌事故 ,迫使矿山停产闭坑。改进采矿方法 ,改变回采顺序 ,加快回采速度 ,是有效地控制地压活动的主要方法。加强研究和观测 ,及时预报 ,采取措施 ,能避免地压活动引起突发性事故 ,防止造成不必要的损失 相似文献

This article discusses the implementation of a pedagogical tool aimed at the refutation of secondary school (grade ten-equivalent) students' persistent climate change misconceptions. Using a lesson study approach, the materials and intervention techniques used were developed collaboratively with geography teachers. The objective is two-pronged: to closely monitor how children learn through refutation-oriented approach and to document how teachers process the experience. A pretest and post-test comparison showed that there was significant improvement in the students' climate change conceptual understanding following the intervention. 相似文献

Making the Connections: Infusing the National Geography Standards into the Classroom 总被引：1，自引：1，他引：0
《The Journal of geography》2012,111(4):459-461
Abstract How will the National Geography Standards change the way teachers teach? The Standards will provide teachers with a geographic perspective that will enable them to teach improved geography content while building geographic skills and knowledge that will benefit their students for the rest of their lives. By taking a fresh look at the content in the curriculum from a geographic perspective, teachers can make connections between the Geography Standards and our own classrooms. The Standards provide information and strategies for teaching geography. They can be used to create lessons which offer opportunities for students to “do” geography and apply the skills they are learning. 相似文献

在ＣＴ／ＭＲＩ诊断学实习课中采用学导式教学法，自学阅读，课堂讨论，最后教师总结的新的教学模式替代传统式的教学模式。作者认为导式教学法有利于学生自学能力的培养，有利于对理论知识的理解和记忆，并且活跃了课堂气氛，因而是影像诊断学实习课中的一种较好的教学方法。 相似文献

This paper describes some special features of the Wenchuan earthquake that affected dam safety. Damage and performance of dams, primarily for four dams over 100 m high located in the affected earthquake area, are briefly described. Lessons learned related to dam safety from this devastating earthquake are preliminarily drawn. As the seismic safety of high dams during strong earthquakes has gained more attention around the world, some critical issues related to dam construction in China are considered and extensively discussed. Questions such as “Why is dam construction necessary in earthquake prone countries such as China?”, “Can we accurately evaluate the seismic safety of high dams in China?”, “Did reservoir impounding of the Zipingpu and Three Gorges Projects trigger the Wenchuan Earthquake in some way?” and “What is the strategic priority of dam safety for large dams in China?” are discussed. Finally, the corresponding tactics with response to the challenge are suggested and recent preliminary progress mainly achieved in IWHR is briefly introduced. 相似文献
