海洋科技人才与成果的摇篮——青岛海洋大学

青岛海洋大学是一所以海洋和水产学科为特色的重点综合大学。1999年11月，经国家批准，成为“九五”期间“211工程”重点建设高校。数年来，青岛海大致力于“211工程”建设，在物理海洋学、水产养殖学、海洋药物学和海洋化学学科4个重点学科建设中取得丰硕成果。     

加大土地整理开发力度为我省经济社会可持续发展作出新贡献

充分肯定我省土地整理开发工作取得的成效 在各级党委、政府的正确领导下,在省耕地保护和造地改田领导小组成员单位的大力配合支持下,我省土地整理和标准农田建设取得了显著成绩.至2004年底,全省通过土地整理等方式建成标准农田1194.38万亩,新增耕地达182.07万亩,为我省连续9年实现耕地占补平衡提供了重要保障.核拨土地整理折抵指标131.09万亩,使用折抵指标批准的耕地104.26万亩,占全部批准建设占用耕地179.27万亩的58%,大大缓解了我省建设用地计划指标严重不足的矛盾.同时,通过土地整理和标准农田建设,提高了耕地质量,改善了农业生产条件.通过农村居民点综合整治,改善了农村的交通环境、生态环境、生活居住环境,开辟了村级集体经济收入财源,壮大了村级经济,为村民办了一些实事、好事,既调动了基层干部的工作积极性,又增强了村级班子的凝聚力,促进了农村基层建设.     

Silicon limitation on primary production and its destiny in Jiaozhou Bay, China——Ⅳ：Study on cross-bay transect from estuary to ocean

The authors analyzed the data collected in the Ecological Station Jiaozhou Bay from May 1991 to November 1994, including 12 seasonal investigations, to determine the characteristics, dynamic cycles and variation trends of the silicate in the bay. The results indicated that the rivers around Jiaozhou Bay provided abundant supply of silicate to the bay. The silicate concentration there depended on river flow variation. The horizontal variation of silicate concentration on the transect showed that the silicate concentration decreased with distance from shorelines. The vertical variation of it showed that silicate sank and deposited on the sea bottom by phytoplankton uptake and death, and zooplankton excretion. In this way, silicon would endlessly be transferred from terrestrial sources to the sea bottom. The silicon took up by phytoplankton and by other biogeochemical processes led to insufficient silicon supply for phytoplankton growth. In this paper, a 2D dynamic model of river flow versus silicate concentration was established by which silicate concentrations of 0.028–0.062 μmol/L in seawater was yielded by inputting certain seasonal unit river flows (m³/s), or in other words, the silicate supply rate; and when the unit river flow was set to zero, meaning no river input, the silicate concentrations were between 0.05–0.69 μmol/L in the bay. In terms of the silicate supply rate, Jiaozhou Bay was divided into three parts. The division shows a given river flow could generate several different silicon levels in corresponding regions, so as to the silicon-limitation levels to the phytoplankton in these regions. Another dynamic model of river flow versus primary production was set up by which the phytoplankton primary production of 5.21–15.55 (mgC/m²·d)/(m³/s) were obtained in our case at unit river flow values via silicate concentration or primary production conversion rate. Similarly, the values of primary production of 121.98–195.33 (mgC/m²·d) were achieved at zero unit river flow condition. A primary production conversion rate reflects the sensitivity to silicon depletion so as to different phytoplankton primary production and silicon requirements by different phytoplankton assemblages in different marine areas. In addition, the authors differentiated two equations (Eqs. 1 and 2) in the models to obtain the river flow variation that determines the silicate concentration variation, and in turn, the variation of primary production. These results proved further that nutrient silicon is a limiting factor for phytoplankton growth. This study was funded by NSFC (No. 40036010), and the Director's Fund of the Beihai Sea Monitoring Center, the State Oceanic Administration.

在社会发展的层面上认识“数字地球”

 本文讨论了“数字地球”的有关问题。指出“数字地球”是人类社会及其活动在网络空间的延伸和拓展,是信息技术带来的社会发展趋势。关于“数字地球”的讨论不应局限在空间信息技术领域,而应该在社会发展的层面上认识它     

改革中学会的生存与发展问题探索--以广西土地学会为例

随着我国改革开放形势的发展及政治、经济体制改革的不断深化,学会作为以非营利性为目的的学术性社会团体组织正在从"婆婆"的暖怀中分离出来,直接面临着生存与发展的严峻考验.如何使自己的航船在改革开放大潮的冲击下不致沉没?如何在国家政治、经济体制改革风浪的席卷中占有自己生存与发展的空间?这是当前学会不可回避而且亟需研究解决的一个重大课题.笔者以广西土地学会为例,从学会所直接面对的现实问题入手,研究学会自身应对生存挑战的能力与把握机遇力求发展的路子.
