论我国南海资源的特点及开发利用对策   总被引：2，自引：0，他引：2  

张莉 《广东海洋大学学报》2002,22(2):13-17

南海我国可管辖的海域面积近200万km^2，具有丰富的生物，油气，矿产等资源，是我国经济与社会可持续发展的强大支持和保障因素，具有海域面积大，资源丰富，区位优势明显，未来开发潜力大等特点，应从强化“寸海寸金”的海洋国土意识出发，通过创新管理体制和运行机制，建立强有力的海上统一执法队伍，按照统一规划，相对集中，由远及近的原则实施重点区域开发战略，全面提升南海国土资源开发利用的水平和效益。  相似文献   

ECOLOGICAL SERIES OF SOIL ANIMALS IN DARLIDAI MOUNTAIN   总被引：1，自引：0，他引：1  

HOUWei-ling FANHong 《中国地理科学(英文版)》2002,12(4):378-382

The ecological series of soil animals under the broad-leaved and pine mixed forest in Darlidai Mountainwas studied. Seven sample plots were selected according to different altitude gradients, which belong to different vegeta-tion types. By investigating and analyzing soil animals in every sample plot it is found that there are 45 groups and 1956individuals, which axe involved in 3 phylums, 7 classes, 16 orders, respectively. The altitude is a key factor which af-fects ecological series of soil animals. Both the groups and individuals of soil animals increase with altitude increasingunder certain conditions, which contrastes with ordinary cases, resulting from special micro-climate in studied area. Thegroups and individuls of soil animals are the most under the broad-leaved and pine forest on the top of the mountain, andthe least under Picea-Abies forest in the foot of the mountain.  相似文献

Heat-shock protein 70 expression in shrimp Fenneropenaeus chinensis during thermal and immune-challenged stress   总被引：4，自引：0，他引：4  

郭振宇焦传珍  相建海 《中国海洋湖沼学报》2004,22(4):386-391

Using western immunoblotting, we obtained heat-shock protein 70 (HSP70) induction data and distribution in different tissues from shrimp Fenneropenaeus chinensis during thermal and immune-challenged stresses. This is probably the first report of the effects of various stressors on the expression of HSP70 in shrimp.HSP70 was prominently induced in hepatopancreas and gills, but not in muscle, eyestalk and hemolymph, when the shrimp were exposed to heat shock and Vibrio anguillavium-challenged stresses. Cold shock and WSSV treatment had no significant effects on the levels of HSP70 expression in all tissues examined. HSP70 induction was greatest after 2 h exposure to heat shock stress, which was elevated after acute heat shock exposure of 10℃ above ambient temperature.  相似文献

印度洋与南亚、西亚沿海的海洋战略角逐（下）     

刘中民 《海洋世界》2008,(12):73-79

美国对印度洋地区的掌控能力明显增强 在冷战时期，美国就在印度洋地区布有海外军事基地。美国印度洋基地群以迪戈加西亚基地为核心，辐射至印度洋沿岸各港口，特别是阿拉伯湾、波斯湾和红海地区。迪戈加西亚地处印度洋中心位置，是印度洋空中和海上交通枢纽，战略地位十分重要。自1971年美国海军从英军手中接管以来，  相似文献

In 1997, IGCP Project No. 410 was established to appraise known records of Ordovician biotas, in order to evaluate one of the greatest-ever diversifications of life on Earth, between 489 and 443 million years ago. Data collection and analysis of biodiversity were coordinated through seven regional teams, and a global“clade” team.  相似文献
