A STUDY ON THE FLOOD STORAGE CAPACITY IN DONGTING LAKE

1 INTRODUCTION Dongting Lake lies south of the middle reach of the Yangtze River in Hunan and Hubei provinces (Fig. 1). On the north side of Dongting Lake, there are the three diversion openings of the Yangtze River named Songzi, Taiping, and Ouchi, and, on the south and west sides, there are the four tributary streams named Xiang, Zi, Yuan, and Li Rivers. The flow of the three diversion openings and the four tributary streams runs into Dongting Lake, and runs out at Chenglingji a…     

渭干河流域"2002·7"特大洪水分析

渭干河是塔里木河流域第六大源流, 位于天山西部南麓, 渭干河干流起点有新疆最大的流域性控制工程--克孜尔水库. 2002年7月下旬天山中西部山区出现大暴雨(雪)过程, 渭干河流域山区降水持续时间长达30 h以上, 山区降水量50 mm左右, 导致5条支流和渭干河干流出现有水文记录以来的最大洪峰, 流量超过警戒流量和危险流量的2～3.5倍, 暴雨(雪)过程结束之后, 融雪型洪峰长时间居高不下. 洪水过程中, 各支流以及暴雨与融雪等多种洪峰遭遇现象很明显. 克孜尔水库入库洪峰流量达3 660 m3*s-1, 经水库调洪错峰, 出库峰值流量为1 000 m3*s-1, 削峰率72.7%.     

滇池微生物解磷与聚磷作用的实验研究及磷的现代沉积与微生物成矿作用

滇池是世界上磷质来源最丰富的湖泊，是研究磷的现代沉积和微生物对磷循环作用及微生物成矿的天然场所。研究发现，滇池微生物种群和数量繁多，但能对磷溶解、转化、迁移、聚集、沉积的微生物主要有解磷菌和聚磷菌两类。这两类微生物与滇池磷的含量之间有一系列规律的相关性：在底泥磷高含量区域，解磷菌的种群和数量与底泥磷含量成负相关关系，与水体磷含量成正相关关系，而聚磷菌的种群和数量与底泥磷含量成正相关关系，与水体磷含量成负相关关系；在底泥磷低含量区域，上述相关性则相反。滇池中这种活着的微生物在自然环境条件下对磷的溶解、转化、迁移、聚集和沉积的作用，对古磷块岩微生物成矿说提供了可靠的依据，而且对以磷为限制性因子的湖、海、江河环境污染的防治提供了理论资料。     

Lithology and palynology of Neogene sediments on the narrow edge of the Kitakami Massif (basement rocks), northeast Japan: Significant change for depositional environments as a result of plate tectonics

Abstract A controversial stratigraphic section, the Taneichi Formation, is exposed along the Pacific Coast of northeastern Honshu, the main island of the Japanese Archipelago. Although most sediments of the formation have long been dated as late Cretaceous, the northern section of it has been assigned to (i) the Upper Cretaceous; (ii) the Paleogene; or (iii) the Neogene. In the present report, we present the data of palynological and sedimentological studies, showing that the northern section should be assigned to the Neogene. A more important point in the present study is that we invoke some basic principles of fluvial sedimentology to resolve this stratigraphic subject. The lignite layers full of Paleogene–Miocene dinoflagellate cysts and pollen assemblages drape over the boulder‐sized (>40 cm in diameter) clasts in the northern section. However, the layers totally consist of aggregates of small lignite chips, indicating that the lignites are allochthonous materials. The mega‐clasts with derived microfossils in the lignites are thought to have been deposited as Neogene fluvial (flood) sediments in the newly formed Japanese Archipelago. Prior to the Miocene, the northern Honshu was part of the Eurasian Plate, thus the boulder‐sized clasts cannot be envisaged as long river flood deposits along the continental Paleogene Pacific Coast. Instead, the mega‐clasts with the draping lignites were probably derived from nearby Miocene highlands in the newly born island arc.
