Richard Pillsbury, a geography professor at Georgia State University, describes traditional life in the lowland South, a region stretching from northern Virginia down to the Gulf coast of Texas:"Smallish hardscrabble farms almost lost in the white heat of a sweltering summer sun as the owners and their help fought swarms of mosquitoes to plant, cultivate and harvest the meagre cotton crop for market."

乔治亚大学地理学教授Richard Pillsbury认为，传统的南部低地生活区，应该指的是在从弗吉尼亚北部一直向南延伸到到德克萨斯的港湾附近。"炎热的气候无情的摧残者贫瘠的小农场，农场主和雇工忍受着黑压压的蚊子的困扰，辛勤劳作，为市场提供微薄的收成。"

The extinction or appearance of these Ostracoda always occurred in a short time interval, and can be correlated locally and globally, so they are of importance in bioeventstratigraphy. This article listed six such biological events in Qaidam Basin and discussed their causes. The extinction of Cetacella reflected temperature decrease at global scale and changes of palaeoclimate zones during the latest Jurassic and the earliest Cretaceous; The rapid decline of Cypridea in the earliest Cretaceous may be a result of the strikes of small planets; at the latest middle-Eocene Austrocypris became extinct, and at Oligocene Hemicyprinotus disappeared. These events related to the changes of the geological conditions at that time. The explosion of Cyprideis at the middle-Miocene was because the rise of Qinghai-Xizang Plateau which resulted in the dry climate and development of salt lakes.

这些水生生物的绝灭或发生均很迅速，在区域或全球范围内均可对比，具有生物事件地层学意义：Cetacella属的绝灭可能是侏罗、白垩纪之交全球性的古气候降温和气候带变化在柴达木盆地的反映；早白垩世之后Cypridea的迅速衰退是地外因素灾变的结果；中始新世晚期的Austrocypris的绝灭、渐新世Hemicyprinotus的绝灭都与当时地质条件的改变存在著内在的联系；中中新世Cyprideis的爆发推断是青藏高原隆升，导致气候乾燥、湖水咸化的结果；而晚更新世晚期1。

Strontium isotope stratigraphy relies on the fundamental principle that the marine strontium is isotopically homogenous world-wide at any time and the 87Sr/86Sr ratio of strontium in seawater of geological history has varied through time. By means of the 87Sr/86Sr ratio of marine carbonate which should record the original composition of sea water, we can date the marine sediments, research global events, such as history of basin subside, sea level change, orogenic events and palaeoclimate variation.

锶同位素地层学根据地质历史中的任何时间全球范围内海水的德同位素组成都是均一的、海水87Sr/86Sr比值随时间变化这一基本原理，利用代表原始海水的海相碳酸盐的87Sr/86Sr比值确定海相地层的年代，研究海平面变化、造山运动、古气候等全球事件，在地层学、沉积学、石油地质学和矿床学等领域中有着广泛的应用前景。
