小石潭记柳宗元从小丘西行百二十步,隔篁竹,闻水声,如鸣珮环,心乐之。伐竹取道,下见小潭,水尤清冽。全石以为底,近岸,卷石底以出,为坻,为屿,为嵁,为岩。青树翠蔓,蒙络摇缀,参差披拂。潭中鱼可百许头,皆若空游无所依,日光下澈,影布石上。佁然不动,俶尔远逝,往来翕忽。似与游者相乐。潭西南而望,斗折蛇行,明灭可见。其岸势犬牙差互,不可知其源。坐潭上,四面竹树环合,寂寥无人,凄神寒骨,悄怆幽邃。以其境过清,不可久居,乃记之而去。同游者:吴武陵,龚古,余弟宗玄。隶而从者,崔氏二小生:曰恕己,曰奉壹。

近年来,我国相关部门实施有效管控,进一步提高了海洋维权巡航执法的时空覆盖率,有方保障了我国海洋国土安全和海上通道安全,我国海洋权益维护和海上安全保障能力进一步加强。在各国海军中,每艘军舰通常以一个海军基地为“母港”,结柬任务后回到这个“家”。与陆军、空军基地相比,各国的海军基地都占地更广,功能更复杂。军舰在这里加油装弹,补充物资,检查修理;海军官兵在这里得到充分休整和训练。为全面過止海洋生态环境恶化趋势,中国海洋管理部门通过健全海域有偿使用制度,创建海洋生态文明示范区,推进“蓝色海湾”“生态岛礁”重大工程建设等措施,加快了构建海洋生态文明新格局的步伐。
