摘　　要：针对海洋测绘基准的特点,本文讨论陆海空间基准现状及存在问题:提出了直接采用CORS网络构建和维持陆海一体化空间基准,创建了基于CORS的陆海一体化现代高精度三维测绘基准模型,初步构建了连云港海域基准服务CORS工作基点网,并尝试建立新一代国家三维地心大地坐标系统(CGCS2000)空间框架结构体系。Aiming at the characteristics of the hydrograpic surveying and charting datum, the status and problems were discussed for the Space Datum of Land ＆ Sea. The author is brought forward the direct use of CORS network to build and maintain the integration of land and ocean space datum. The modern high-precise three-dimensional Integrative Land ＆ sea Model of the surveying and mapping datum was oreated. The CORS service point network was initially built in Lianyungang sea area. To achieve national unity CGCS2000 geocentric geodetic coordinate system, dynamic three-dimensional space frame structure was established.
