Based on the comparative analysis of the attached sea charts in Chen Shoupeng’s Xin Yi Zhong Guo Jiang Hai Xian Yao Tu Zhi （《新译中国江海险要图志》）and its source charts-British Admiralty Chart，we suggest that the redepiction has the following characteristics：The sheet dividing is based on political district rather than sea-route. The depiction of the coastline，river，mountain and reef in the attached sea charts inherits the attributes of British Admiralty Chart，which improved the accuracy of the topography. And these charts abandoned the mathematical elements in depicting process which were necessary in admiralty charts such as longitude and latitude coordinates，water depth，proportion，and compass. The attached sea charts in Tu Zhi indeed enhance people’s cognition level of coastal topography，however，it do not break through the framework of Chinese antique maps，nor do it have the navigation function. The coastal defense value of Tu Zhi still depend on the text rather than chart. The publication of Tu Zhi can be regarded as a translation of British nautical knowledge under the guidance of the “Westernized Chinese Style” carried out by scholars in late Qing period who faced the defeat of the Sino-Japanese War and desired to reinvigorate the coastal defense.
