After analyzing the impacting factors of natural vulnerability along the Pearl River mouth, the paper divides the coastline of approximately 412km into 25 15-minute gird cells. For assessment purposes, the six variables including geography, relative sea-level change, average tide range, regional slope, shoreline erosion or accretion rates and tropic cyclone impacting frequency are selected as assessed variables. Once each section of coastline is assigned a risk value for each specific data variable, the costal vulnerability index can be useto calculate the natural vulnerability of the areas along the Pearl River mouth. After that, the paper develops a database for assessment of coastal vulnerability to sea-level rises and protracts a 1:2,000,000 vectors CVI map of the coastlines along the Pearl River mouth.

为了探讨不同海岸带对未来海平面上升的自然脆弱性，本文以珠江口沿岸作为研究个案，在分析珠江口沿岸自然脆弱性的影响因子的基础上，把珠江口沿岸412km岸线划分为25个15′×15′的网格单元，选取了地质、海平面上升率、平均潮差、区域海岸坡度、海岸侵蚀/堆积率、热带气旋影响频率6个评价指标，应用CVI指数评价公式对珠江口地区进行海岸脆弱性评价，并建立海岸脆弱性评价数据库，绘制了珠江口沿岸1：2，000，000的数字化CVI图。

在总阐发外洋查察配方，然后保持配方洋某个身不合的数度或配方的某个变度便可当即得知甘休，务必从头测色，从头取回颜色，从头配色或挨近配方边缘。

The experimental results showed that the frictional factor periodically fluctuated with the time variable, and its amplitude was obviously affected by the change of Reynolds number and pipe diameters. The amplitude and average value of frictional factor both decreased with the increase of Re number, but the bigger the tube diameter was, the larger the amplitude of frictional factor was.
