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 。
Based on the studies in sea - level rise and response of coastal zone by domestic and foreign researchers , integrated with the essential characteristics of jiangsu coast and the radiate sand ridges , laid emphasis on the effects of sea - level rise on the radiate sand ridges and the tiaozini sands in it ' s center region , the following case were discussed in the paper . ( 1 ) the recent relative sea - level rise in the region of the radiate sand ridges found on the structural and sedimentary features of the radiate sand ridges , the rate of regional land subsidence was calculated ( structural , balanced and compressed subsidence were considered respectively ) . the latest assessment of global sea - level rise in the past century that was carried out by ipcc was cited 本论文在总结国内外对海面上升及其对海岸带影响的研究基础上，结合江苏海岸及辐射沙洲区的基本特征，以相对海面上升对辐射沙洲及其中心部位的条子泥的影响为重点，讨论了以下几个方面的问题： ( 1 )辐射沙洲区近期的相对海面变化根据辐射沙洲区的构造和沉积特征，对区内地面沉降速率进行分项计算(包括构造沉降速率、均衡沉降速率和压实沉降速率) ，并引用ipcc最近对过去100年来全球绝对海面上升速率的评估。
Compared to the basins in east guangxi , the basin of north guangxi is characterized by lower depositional and tectonic subsidence rate during rifting , longer thermal subsidence , later inflexion point from rifting to foreland buckling , as well as later inflexion point separating stable stage from active stage during foreland - buckling 但与桂东大瑶山地区相比，桂北兴安地区在裂陷阶段的沉积速率和构造沉降速率明显偏低；热沉降阶段的持续时间偏长；裂陷阶段与前陆挠曲阶段的分界拐点偏晚；前陆挠曲阶段，由构造宁静期的缓慢沉降向构造活动期的快速沉降转化的分界拐点也偏晚。
With the help of settlement plate , the author conducts observation more than 2 years on highway embankment built on the yiluo river alluvial flat in henan province . as a result many of data have been obtained . through analysising and studying these data , the occurring process of settlement and rate of settlement of the alluvial flat soft clay base under embankment have been found 本文以伊洛河河滩相软土为研究对象，利用沉降板对路堤荷载作用下的软土地基沉降进行了长达两年多的观测，获得了大量的沉降数据，通过对这些数据的分析研究，推算出沉降系数m _ s和固结参数，并得到了河滩相软土地基固结沉降速率的变化规律。
