accretion rate造句

• To discuss the natural vulnerability of different coasts to future sea-level rise, the paper selects the coasts along the pearl river mouth as the studied area . 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
  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1515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。
