剥蚀速率 meaning in English
denudation rate
rate of denudation
Examples
- The maximal depth of source rock in china is distributed in 3000 - 4000 metres , the average subsidence rate of a basin is no more than 100 metres each million year , and maximal subsidence rate is more than 300 metres each million year ; the uplift rate is also no more than 100 metres each million year , and maximal uplift rate is more than 300 metres each million year , the maximal degradation thickness is more than 2000 metres
中国含油气盆地烃源岩最大埋深主要分布在3000 - 4000m 。盆地沉降速率一般在100m / ma的范围内，最大可达300m / ma ；经历抬升型盆地抬升剥蚀速率一般在100m / ma的范围内，最大也可达300m / ma ，剥蚀厚度最大可大于2000m 。 - Therefor , in the light of theory and methods of karst hydrogeomorphology and the knowledge of transformation , balance and variation of matter and energy in karst drainage basin , we can examine stone forest within a specific scope of time and space , and reveal the mechanism and the development model of stone forest with the help of the principle of the mutual response processes among base - level , water flow and forms . just based on the understanding above , the paper , with a special reference to the lunan stone forest which is the best developed one in china , discusses the hydro - geomorphlogical structure of the bajiang river , geomorphological types and spacial distribution feature of the stone forest , and studies the erosion rate on the top of stone forest , soil erosion rate , sub - soil dissolution rate and their combined influences on the evolution of stone forest , furtherly brings forward and demostrates the " tri - level erosion " mechanism for the development of stone forest
正是基于这种认识，本文以我国石林发育最完美的路南石林为研究对象，研究了巴江喀斯特流域的水文地貌结构特征、石林的形态类型及其空间分布特征；探讨了石柱顶部的剥蚀速率( a ) 、表土剥蚀速率( s ) 、土下溶蚀强度( c )及其组合对石林发育的影响，提出并论证了路南石林发育的“三重剥蚀”机制；通过对石林发育必备条件的剖析，以及对巴江喀斯特流域演变阶段的定量研究、水文地貌系统的空间耦合分析，探讨了巴江喀斯特流域的演变与路南石林发育间的关系，并结合该流域的演化史，提出了巴江喀斯特流域演变与路南石林发育的模式。
