Abstract : the restoration of the riparian vegetation disturbed by human activities is one of the hotspots of watershed ecology . through interpreting the images of remote sensing in 1985 and 1999 , the basic information of forest resources of lushuihe forest bureau , which is a typical forest area of changbai mountain , was obtained with support of gis . by dividing land covers of lushuihe area into 10 types ( water body , residential land , stump land , farming land , wetland , mature conifer forest , midlife conifer forest , mature broadleaf forest , midlife broadleaf forest , and man - made young forest ) and dividing the riparian zone into four buffers ( in turn , 1000 , 2000 , 3000 , 4000 m away from the river ) , the changes of riparian forest resources during 1985 - 1999 were analyzed . the results showed that the deforestation intension has obviously decreased and the whole environment has been evidently improved , but the riparian ecosystem was still flimsy . in buffer 1 , 2 , 3 , the area of midlife conifer forest increased largely , but the areas of other types of land covers all decreased . midlife conifer forest had a comparatively good status in the three buffers . in buffer 4 , midlife conifer forest , mature conifer forest , and mature broadleaf forest formed a forest - age rank that is helpful to stabilize the forest ecosystem and exert its functions . area percentage of wetland decreased in buffer 1 , buffer 2 , and buffer 3 , even in buffer 4 in which forest ecosystem rehabilitated comparatively well , so protecting and rehabilitating wetland is a very difficult task 文摘:本文对两期遥感图像进行解译,并在gis支持下提取露水河林业局主要河流两岸各缓冲区森林资源信息,经分析得到各类地物在1985年及1999年的变化趋势.结果表明:在河流沿岸对森林的采伐强度1999年较1985年明显减小,整体生态环境较1985年有所改善.在缓冲区1 , 2 , 3除中龄针叶林大幅度增加外,其它地物类型面积均减少,由此可以看出,在这三个缓冲区内针叶林得到了较好的恢复.在缓冲区4内,中龄针叶林、成熟针叶林、成熟阔叶林形成一个林龄梯队,有利于森林生态系统的稳定与功能的发挥,十五年间缓冲区4受到的干扰相对较小.湿地数量在四个缓冲区内均有所减少,虽然在缓冲区4内森林生态系统恢复的较好,但湿地面积仍有所减少,说明保护及恢复湿地资源是一件非常艰巨的任务,必须引起高度重视.图5表2参12
The author finded out that the rice in the mediums with phosphorus and phosphate rocks can grow well , the quantity of the algea and the phosphorus in the mediums increase . on the contrary , in other mediums the rice appear to be short of phosphate 其中，全磷培养基和含磷矿石粉的无磷培养基中杂交水稻正常生长，沙角衣藻生物量较实验前有所增长；由于实验梯队磷矿石的转化作用，使培养基有效磷浓度均较实验前也有所增长；而其他实验组水稻均出现不同程度的缺磷表征。
This paper first introduces the historical development of one of the key research institutes of humanities and social sciences in universities in china since the 1970s , and it then concludes that this key institute - the centre for linguistics and applied linguistics ( clal ) in the guangdong university of foreign studies ( gdufs ) has accumulated five aspects of experience in its development , proposing clal construction and management as system engineering 摘要文章总结并介绍广东外语外贾大学外国语言学及应用语言学研究中心作为国家级重点学科研究基地的历史沿革及其建设经验，着重阐述五个方面的经验：一、把学科建设当作系统工程来抓；二、确定课题促成长，成果促教学的发展思路；三、培养创新意识，产出精品成采；四、加强梯队建设，培养后备力童；五、加强学术交流，扩大学科影响。
A recent questionnaire survey and analysis organized and conducted by us shows that the undergraduate teaching administration of jiangsu university at present should focus on the conformity and optimizing of academic subjects , make effort to reinforce the full - time staff construction mainly with the echelon construction of academic subjects , enhance in an all - round way the training of undergraduates ' learning capability and technical ability of experiment and practice , put emphasis on bilingual teaching , give full play to the supporting function of the resources available such as library books for teaching , give a vigorous impetus to the innovation of administration system , hence to realize the second leap of the level of undergraduate teaching administration of jiangsu university 作者根据教育部本科教学水平评估指标体系，组织了一次问卷调查，结果显示当前学校本科教学工作应集中精力整合和优化学科结构，着力加强以学科梯队构建为主线的专任教师队伍建设，全面加强学生学习能力培养和实验实习技能训练，重视双语教学，充分发挥图书信息等资源对教学工作的支撑作用，积极推进管理制度创新，以此实现学校本科教学工作水平的二次飞跃。
