| 1 | 美国南达科他州Black Hills国家森林公园2000年森林火灾后植被恢复过程研究(英文)显示文摘森林火灾在景观上往往造成不同程度的森林冠层损失,而冠层影响光合作用和蒸散,因此刻画灾后森林冠层恢复的轨迹对于了解生态系统过程具有重要意义。森林冠层的损失和恢复通常采用叶面积指数(LAI)或其它能够反映冠层光合能力的植被指数进行表征。本研究中,我们采用Terra卫星搭载的中分辨率成像光谱仪(MODIS)的长时间序列影像(2000-2009年)来重建火灾后森林冠层恢复的过程。以美国南达科他州布莱克山国家森林公园(The Black Hills National Forest, South Dakota)为例,该地区在2000年8月24日经历了一次大的自然火灾,烧毁了近33 785 ha森林,其中大部分是美国黄松林。基于LAI的研究表明,植被冠层光合能力在3年内(2001-2003年)基本恢复,这主要来自于林下未烧毁草地在灾后的快速生长;火烧迹地的NDVI和EVI在这3年内也呈现恢复的态势。可见,LAI、NDVI和EVI在火灾几年之后便难以有效地识别火烧迹地。然而,陆地表面水分指数(基于近红外和短波红外波段的遥感标准化指数,简称LSWI),能够有效地识别和追踪火烧迹地至今的整个过程(2000-2009年)。这一研究结果也使得采用其它具有近红外和短波红外波段的传感器研究森林火灾迹地恢复和干扰过程成为可能,其中包括Landsat 5 TM影像(可追溯至1984年)。更长时间序列的数据对于研究森林火灾灾后生态系统干扰和恢复过程、森林演替模拟以及碳循环具有重要的支撑作用,LSWI指标证明能够有效地刻画这一过程。 | 肖向明 Chandrashekhar BIRADAR Audrey WANG Sage SHELDON 陈友民 | 2011 | Journal of Resources and Ecology2011，2，2： | 2 |
| 2 | Assessment of knowledge and attitude about basic life support among dental interns and postgraduate students in Bangalore city,India显示文摘BACKGROUND: Life-threatening emergencies can occur at anytime, at anywhere and in anyone. Effective management of an emergency situation in the dental office is ultimately the dentist's responsibility. The lack of training and inability to cope with medical emergencies can lead to tragic consequences and sometimes legal complications. Therefore, health professionals including dentists must be well prepared to deal with medical emergencies. This study was undertaken to assess the knowledge about and attitude towards basic life support(BLS) among dental interns and postgraduate students in Bangalore city, India.METHODS: A cross sectional survey was conducted among dental interns and postgraduate students from May 2014 to June 2014 since few studies have been conducted in Bangalore city. A questionnaire with 17 questions regarding the knowledge about and attitude towards BLS was distributed to 202 study participants.RESULTS: The data analyzed using the Chi-square test showed that dental interns and postgraduate students had average knowledge about BLS. In the 201 participants, 121(59.9%) had a positive attitude and 81(40.1%) had a negative attitude towards BLS.CONCLUSIONS: Cardiopulmonary resuscitation should be considered as part of the dental curriculum. Workshops on a regular basis should be focused on skills of cardiopulmonary resuscitation for dental students. | Dhage Pundalika Rao Narayan Suvarna V Biradar Mayurnath T Reddy Sujatha BK | 2015 | World Journal of Emergency Medicine2015，6，2： | 2 |
