对长江下游铁黄沙湿地植被和底栖动物的群落结构进行了研究。结果表明：铁黄沙植被结构相对简单，主要的优势种为芦苇、藨草、菰。芦苇群落带生物量较高，伴生有十几种其他高等植物；藨草群落带生物量较低，群落结构比较单一，但是盖度范围和密度较大。共调查到大型底栖动物10种，以甲壳类动物和环节类动物为主。前者主要分布在高潮滩，并随高程降低逐渐减少，后者主要分布在中低潮滩，中潮滩生物种类数最多。优势种主要为无齿螳臂相手蟹、谭氏泥蟹和河蚬。底栖动物的生物多样性以藨草群落带最好，潮下光滩群落带最差，芦苇群落带和菰群落带介于其中。

The vegetation and the community structure of zoobenthos of ferric yellow-sand wetland in the lower Yangtze River were studied. The results showed that the vegetation structure of ferric yellow-sand was relatively simple, its dominant species were reed, Scirpus triqueter and Zizania caduciflora. There was a relatively higher biomass in reed community belt, and more than 10 species of other higher plant accompanied with it; Scirpus triqueter community belt had relatively low biomass and simple community structure, but its coverage range and coverage density were relatively larger. Moreover, total 10 species of macrobenthos had been investigated, which mainly were crustacean and annelid. The former mainly distributed in the beach with high tide, and it gradually decreased with reducing beach elevation; the latter mainly distributed in the beach with middle tide and low tide, among which the beach with middle tide had the most number of biological species. The dominant species of zoobenth

湖南黄沙坪矿区是湖南省内矿产资源最丰富的地区之一，在几十年的矿产开采中，已经有不少学者与专家对黄沙坪矿区的岩浆岩特征进行过分析与探讨，在前人研究基础上，本文依托《湖南省桂阳县黄沙坪铅锌矿接替资源勘查》项目，通过收集整理矿区的资料、野外地质考察及室内系统的光薄片显微镜下鉴定等工作，对黄沙坪矿区岩浆岩地质特征及其与成矿的关系做出了较全面的总结。

Huangshaping mine is one of the richest mineral re_sources in Hunan,in the decades of mineral exploration,the Igneous rock geological characteristics of Huangshaping mine analysised and discussed by many scholars and experts,On the basis of predecessors’ research,According to the 《Huangshaping Lead zinc mineral resources survey in Hunan province Guiyang county》,By collecting and sorting the data of mine , field geological investigation and microscopic iden_tification indoor,To have a comprehensive summary of the Igneous rock geological characteristics and the relationship with mineralization of Huangshaping mine in Hunan.

以黄沙、沸石、废菌糠和泥炭（浸出液和固态）为基质在光照培养箱内对大羽藓进行栽培,利用分枝长度、分枝数、生物量等指标评价了大羽藓的生长状况,探讨了不同基质栽培对大羽藓生长的影响.结果表明：液态栽培中,废菌糠浸出液栽培大羽藓生长效果最佳,其次是泥炭、黄沙、沸石,蒸馏水效果最差；废菌糠浸出液栽培大羽藓60 d其分枝长度为5.13 cm,一级及二级分枝数分别为3.27和2.30个,鲜质量及干质量分别增长34.09和17.22倍.固态栽培中,泥炭（固态）栽培大羽藓生长效果最佳,其次是黄沙、沸石、废菌糠,林下土壤栽培效果最差；泥炭（固态）栽培大羽藓60 d,其分枝长度为4.11 cm,一级及二级分枝数分别为3.17和1.73个,鲜质量及干质量分别增长46.49和19.56倍.

Effects of different matrices(the leaching liquid and solid),sand,zeolite,waste compost and peat,on the growth of Thuidium cymbifolium cultured in illumination incubator were studied.The cover degree,branch length,branch number,biomass and relative moisture content were determined to evaluate the growth of Thuidiumcymbifolium.The results showed that waste compost fermentation liquid was the best for the growth of Thuidiumcymbifolium in liquid culture test,followed by the liquid of peat,sand and zeolite,and the effect of distilled water was the worst.After cultivated in waste compost fermentation liquid for 60 d,Thuidium cymbifolium branch length was 5.13 cm,the number of the primary branches was 3.27 and the second branches was 2.30,fresh weight and dry weight increased 34.09 times and 17.22 times re-spectively.The peat was the best for growth of Thuidium cymbifolium in solid culture test,followed by the solid of sand,zeolite and waste compost,and the effect of forest soil wa

冯山，北宋中期蜀中诗人，颇有盛名。其家世个人资料匮乏，今无系统研究。根据古籍相关记载，对其家世谱系略作整理，编次其个人行年及其创作，试图系统地研究冯山。对《安岳集》的版本作详细地考证论述，以期对四川文学研究略有补益。又据《永乐大典》补冯山《黄沙村》七律一首。

Feng Shan was a famous poet in Sichuan in the Song Dynasty. Because of the deficiency of historical re-cords, there is not a systematic study of him. According to the records of ancient books, the essay mainly gives a systematically textual research on Feng Shan,such as his family and biography,the version of Anyue Poetry,hoping to be of help for the literature study in Sichuan. Besides,the outhor finds one of Feng Shan’ poems uncollected in other existing books from The Yongle Canon.

为研究有关潮汐通道浅水槽建港问题,以辐射沙脊群黄沙洋水道末端的条渔港为例,首先,进行了自然条件分析;其次,构建二维水动力数学模型,根据实测资料对水动力模型进行验证,并对工程前后整体海区的潮流流态、特征点横流大小进行了分析;最后,应用泥沙经验公式计算条渔港区港池及航道的年回淤量。以上数据可为港区方案设计提供科学依据。

Taking Tiaoyugang as a case study, the port, which locates at the end of the Huangshayang channel’s of radial sandridges, is being built in shallow tank of tidal channel. First of all, the natural conditions are analysed. Then, based on the calibration of two-dimensional hydrodynamic mathematical model, the results act in accord with the measured data. The tide current field of whole computational region and the characteristic point’s cross flow on before and after the project are discussed. Finally, using the sediment experience formula calculates the yearly deposition quantity in the harbor basin and channel. The conclusion can provide the scientific basis for the port design.
