[Objective] The aim was to assess the status quo of animal and plant resources in Turks River after the construction of the reservoir.[Method] Through field investigation,document check and sample identification,the distribution of animal and plants resources in Turks River after the construction of the reservoir was studied and corresponding protection measures were proposed.[Result] Under the influence of reservoir,there were fifteen types of rare animals,one species of national primary protected animals,seven species of national secondary protected animals,one species of provincial primary protected animals,six species of provincial secondary protected animals;there were twenty one species of rare plants,including two species of national secondary plant,five species of national tertiary protected animals,six types of Xinjiang primary protected plants,two species of Xinjiang secondary protected plants and six types of tertiary protected plants in Xinjiang.Protective policies for the land ecological environment were proposed,including corresponding compensation according to the rules and policies of government,plans being formulated for rare species protection,construction of natural reserves and artificial breeding base,usage of the environment in the reservoir and changes of ecological situation etc.[Conclusion] The study provided basis for the protection of animal and plants resources in Turks. 展开更多

The severe and rapid attack on the Caicos pine Pinus caribaea var. bahamensis(Pinaceae) by the nonnative invasive pine tortoise scale, Toumeyella parvicornis, has resulted in the death of most of the trees in the Turk... The severe and rapid attack on the Caicos pine Pinus caribaea var. bahamensis(Pinaceae) by the nonnative invasive pine tortoise scale, Toumeyella parvicornis, has resulted in the death of most of the trees in the Turks and Caicos Islands(TCI) in just over a decade. Local and international conservation efforts have enabled the necessary multi-disciplinary research, data gathering, and monitoring to develop and implement a restoration strategy for this endemic tree from the Bahaman archipelago. The native plant nursery established on North Caicos and horticultural expertise acquired throughout the years were crucial to the successful rescue of Caicos pine saplings from the wild populations and cultivation of new saplings grown from locally sourced seeds. These saplings have been used to establish six Restoration Trial Plots on Pine Cay and a seed orchard on North Caicos in TCI. Core Conservation Areas(CCAs) for the Caicos pine forests have been identified and mapped. To date, forest within the Pine Cay CCA has been supplemented by planting more than 450 pine trees, which have survived at a high(>80%)rate. 展开更多

采用光学和化学分析方法对津巴布韦Bubi绿岩带内Turk金矿伴生的黄铁矿进行形态、同位素和微量元素分布特征研究,认为碳酸盐岩中黄铁矿的硫同位素δ34S值,随黄铁矿形态变化而变化,表明硫来源是多元的。大多数样品硫同位素δ34S值近于0‰... 采用光学和化学分析方法对津巴布韦Bubi绿岩带内Turk金矿伴生的黄铁矿进行形态、同位素和微量元素分布特征研究,认为碳酸盐岩中黄铁矿的硫同位素δ34S值,随黄铁矿形态变化而变化,表明硫来源是多元的。大多数样品硫同位素δ34S值近于0‰,反映了岩浆作用提供了硫的主要物质来源。少量样品的硫同位素δ34S值介于+4‰~+16‰之间,反映一部分硫来自海水。砷及其他元素的分布特征表明在碳酸盐岩层内存在几个不同世代的黄铁矿。早期富含砷的黄铁矿内金有一定程度的富集,但在碳酸盐岩内黄铁矿中金的浓度太低,不能产生金的显著富集。而在变玄武岩中,金明显富集,它是晚期含矿流体沿微细剪切带渗透,形成石英-方解石-黄铁矿组合,并把原来自形的黄铁矿破碎呈角砾状,伴随裂隙金生成。 展开更多

A software has been developed to overcome the difficulties related to depositional model determination in Geosciences. The implemented methods, Walker, Harper and Turk methods, based on Markov process and Markov chain analysis, have been used in a case study. The results of the analysis are consistent with previous works. The analysis shows also that the results are accurate and do not rely on the used method. Therefore, the obtained depositional sequence is suitable to build a depositional model on which reliable sequence stratigraphic studies can be based. 展开更多

Kutadgu Bilig(Gracious Knowledge),a common cultural monument of modern Turkic peoples,is a valuable historical,theoretical,and methodological source that reveals the artistic and political thinking of the 11th century,shapes the life and spiritual culture of society,and explains the prospects for governing the state.In this work,which is a philosophical and legal political treatise(Book of Government)of the history of Turkish-Islamic culture of the 11th century,the general terms of the government strategy,which forms the basis of public administration,are widely interpreted from different aspects.Kutadgu Bilig,which reveals the unique artistic treasures of the Turkish language and Turkish artistic and political thinking,shows that the proper regulation of relations between the people and the government is the most important factor in public administration.Kutadgu Bilig,a philosophical and legal political treatise of the Turkish-Islamic cultural history of the 11th century,which contains very important theoretical and practical knowledge in the field of state building and administration,has not lost its actuality since it reflects the theoretical and methodological principles of public administration. 展开更多
