| 1 | Development characteristics of interlayer oxidation zone type of sandstone uranium deposits in the southwestern Turfan-Hami basin显示文摘The Turfan-Hami basin is the key area for the exploration of sandstone uranium deposits of the leachable interlayered oxidation zone type. The aim of this study is to shed light on the development characteristics of this type of uranium deposits and provide new clues to further exploration. Detailed study led to the following conclusions: (1) uranium orebodies are hosted mainly in the lower Middle Jurassic Xishanyao Formation and the lower Lower Jurassic Badaowan Formation; (2) the formation of uranium orebodies is closely related to organic matter; (3) the front of the interlayered oxidation zone is snake-shaped in plane and imbricated in the section; the more the interlayered oxidation zone and zonation are developed, the better the uranium mineralization will be; according to lithological and geochemical characteristics, the oxidation zone, the oxidation-reduction transitional zone and the reduction zone can be distin-guished; (4) the development of interlayered oxidation zone is controlled by geological structure, underground water, sandstone permeability and other factors; (5) sandstone uranium orebodies hosted in the interlayered oxidation zone are very complicated in spatial distribution, of which some are rolled and plated in shape and some are highly variable in shape. | YANG Dianzhong XIA Bin WU Guogan | 2004 | Science China Earth Sciences2004，47，5： | 7 |

| 8 | Trophic gauntlet effects on fisheries recovery:a case study in Sansha Bay,China显示文摘Low biological productivity causes ecosystem energy deficiency.Sansha Bay is an important spawning and nursery ground for migratory fish in the East China Sea(ECS).There is significant mariculture in this area,but stock enhancement programs and seasonal fishery closures have failed to recover populations of the commercially important species,Larimichthys crocea.We want to figure out the potential reason of unsuccessful L.crocea resource in recent 30 years.In this study,the trophic status of L.crocea,the food source proportions of L.crocea and zooplankton,and the food web structure and functioning of Sansha Bay was analyzed.A high nutrient low chlorophyll phenomenon was observed:this prevented harmful algal blooms,and phytoplankton growth was restrained by intensive macroalgal culture,resulting in a low abundance of zooplankton in Sansha Bay.Phytoplankton was the most important food source of zooplankton,and zooplankton was the greatest food source of juvenile L.crocea.Analyzed L.crocea suffered from starvation.Crucially,most of the phytoplankton was not used efficiently in the Sansha Bay ecosystem.This study suggests that trophic bottleneck,caused by food limitation,is a potential reason for unsuccessful fishery recovery in enclosed bay with macroalgal culture. | Bin Xie Cheng Huang Ya Wang Xijie Zhou Guogan Peng Yancheng Tao Jiaju Huang Xiaoqing Lin Lingfeng Huang | 2021 | Ecosystem Health and Sustainability2021，7，1： | 0 |
