It is suggested thatXiaojiawan-Yazigang and Sanxianhu-Chapanzhou regions are favourable for Quaternary biogas exploration of the basin .

利用水流能量指数，分析了洞庭盆地第四纪沉积环境的演变特征。

The evolution of sedimentary environment in the Quaternary in Dongting Basin is analyzed by using the flow energy index .

受构造沉降、泥沙淤积和人类活动三大因素综合作用的影响，南洞庭盆地呈现非均匀沉降特点，造成了南洞庭盆地区防洪和生态形势严峻。

The southern Dongting Basin has the characteristics of differential subsidence , which influences flood and ecology , because of the tectonic subsidence , sediment deposition and human activities .

研究洞庭盆地第四系中玛瑙的分布与富集规律，是揭开盆地生成与发展的重要途径之一。

To investigate the rules governing the dis-tribution and concentration of agate in the Quarternary of Dongting Basin is the key to solve the problems of the formation and development of the basin .

在纵向尺度上，江汉-洞庭盆地以及周缘造山带的上地壳结构变化不大，中地壳和下地壳则普遍受到现今构造活动的改造，以致岩石的结构发生了一定的变化。

Longitudinally , the upper crust structure in Jianghan-Dongting basins and their marginal orogenic belts does not change much , the middle and lower crust were generally transformed by modern tectonic activities , leading to certain changes in lithospheric structure .

湖南省洞庭盆地位于扬子准地台江南隆起带的中段，前白垩纪是扬子准地台的组成部分，白垩纪第三纪成为断陷坳陷型内陆沉积盆地，古近系在全盆地分布广泛。

The Permian and the Paleogene sediments are major source rocks in the Dongting Basin which is located in the middle of the Yangzi Sub-plate in South Central China , prior to becoming an inland depression during the Cretaceous Paleogene .

洞庭盆地的构造沉降量虽然在一定程度上缓解了洞庭湖不断萎缩的趋势，但构造沉降对洞庭湖区的防洪形势却是不利的。

The tectonic subsidence capacity of the Dongting Basin restrains the shrinking tendency of Dongting Lake to a certain extent , but the tectonic subsidence is harmful to the situation of preventing flood disasters in the region of Dongting Lake .

利用构造分析结果、震源机制解和现场应力测量资料，获得江汉洞庭盆地及邻区新生代4个时段构造应力场主应力的优势分布。

By using the results of tectonic analysis , focal mechanism solution and site geo stress survey we get the predominant distribution of principal stress of tectonic stress field in the Jianghan Dongting basin and its vicinal areas in four periods since Cenozoic .

认为洞庭湖盆地周缘的丘陵山区处于相对缓慢抬升之中，其上升速率为032～229mma；盆地区处于缓慢的沉降之中，其速率约为5～10mma。

It considers that the hill near Dongting Lake basin is in the process of relatively slow uplifting with the speed of 0.32-2.29mm/a and the basin area is in the slow subsidence process with the speed of 5-10 mm / a.
