摘　　要：由于佛冈县未建立CORS,且广东省CORS在产业园信号不稳定、高程差异过大,因此亟需运用现代测绘技术手段构建园区测绘基准体系。详细介绍了广佛产业园现代测绘基准体系的建立过程,包括高精度GNSS控制网、精密水准网、基于2000国家大地坐标系(CGCS2000)的基准转换模型和区域高程模型的建立,为类似的园区测绘基准建设提供了参考。Fogang has not established the CORS system yet,and the signal of CORS system of Guangdong Province is unstable in the industrial park.Thus,it is urgent to build the surveying and mapping datum based on modern surveying and mapping technology.In this paper,we intro-duced the establishment process of modern surveying and mapping datum system in Guangzhou-Fogang industrial park in detail,including the es-tablishment of high-accuracy GNSS control network,precision leveling network,regional elevation model and datum transformation model based on CGCS2000,which could provide reference for similar industrial parks.
