Academic Editors: Jun Liu, Gang Liu and This Rutishauser Received: 1 February 2017; Accepted: 4 May 2017; Published: 8 May 2017 Abstract: Ice, snow, and rime are wonders of the cold season in an alpine climate zone and climate landscape. With its pure, spectacular, and magical features, these regions attract numerous tourists. Ice and snow landscapes can provide not only visually-stimulating experiences for people, but also opportunities for outdoor play and movement. In China, ice and snow tourism is a new type of recreation; however, the establishment of snow and ice in relation to the suitability of the surrounding has not been clearly expressed. Based on multi-source data, such as tourism, weather, and traffic data, this paper employs the Delphi-analytic hierarchy process (AHP) evaluation method and a spatial analysis method to study the spatial differences of snow and ice tourism suitability in China. China’s ice and snow tourism is located in the latitude from 35◦N to 53.33◦N and latitude 41.5◦N to 45◦N and longitude 82◦E to 90◦E, with the main focus on latitude and terrain factors. -

Report on Domestic Animal Genetic Resources in China
Country Report for the Preparation of the First Report on the State of the World’s Animal Genetic Resources Report on Domestic Animal Genetic Resources in China June 2003 Beijing CONTENTS Executive Summary Biological diversity is the basis for the existence and development of human society and has aroused the increasing great attention of international society. In June 1992, more than 150 countries including China had jointly signed the "Pact of Biological Diversity". Domestic animal genetic resources are an important component of biological diversity, precious resources formed through long-term evolution, and also the closest and most direct part of relation with human beings. Therefore, in order to realize a sustainable, stable and high-efficient animal production, it is of great significance to meet even higher demand for animal and poultry product varieties and quality by human society, strengthen conservation, and effective, rational and sustainable utilization of animal and poultry genetic resources. The "Report on Domestic Animal Genetic Resources in China" (hereinafter referred to as the "Report") was compiled in accordance with the requirements of the "World Status of Animal Genetic Resource " compiled by the FAO. The Ministry of Agriculture" (MOA) has attached great importance to the compilation of the Report, organized nearly 20 experts from administrative, technical extension, research institutes and universities to participate in the compilation team. In 1999, the first meeting of the compilation staff members had been held in the National Animal Husbandry and Veterinary Service, discussed on the compilation outline and division of labor in the Report compilation, and smoothly fulfilled the tasks to each of the compilers. -

Determination of Geochronology and Sedimentation Rates of Shallow Lakes in the Middle Yangtze Reaches Using 210Pb, 137Cs and Spheroidal Carbonaceous Particles
Determination of geochronology and sedimentation rates of shallow lakes in the middle Yangtze reaches using 210Pb, 137Cs and spheroidal carbonaceous particles Xu Chen1*, Qianglong Qiao1, Suzanne McGowan2, Linghan Zeng1,2, Mark A Stevenson3, Lei Xu1, Chunling Huang1, Jia Liang1, Yanmin Cao4 1State Key Laboratory of Biogeology and Environmental Geology, School of Earth Sciences, China University of Geosciences, Wuhan 430074, China 2School of Geography, University of Nottingham, Nottingham NG7 2RD, UK 3School of Natural and Environmental Sciences, Newcastle University, Newcastle- upon-Tyne NE1 7RU, UK 4College of Resources and Environmental Science, South-Central University for Nationalities, Wuhan 430074, China *Corresponding author; e-mail address: [email protected] https://doi.org/10.1016/j.catena.2018.11.041 Catena Abstract: Accurate chronologies for recent sediments of shallow lakes in the Yangtze floodplain are critical to calibrate proxy records for reconstructing environmental changes during the past century. This study presents the results of detailed 210Pb analysis from eight lake sediment cores collected from the middle Yangtze reaches, 210 southeast China. Unsupported Pb activities generally declined exponentially with mass depth in the eight cores. The chronologies and sedimentation rates for the sediment cores were calculated using different 210Pb-based mathematical models. The 137Cs chronomarker (i.e. the 1963 fallout peak) and the spheroidal carbonaceous particle (SCP) chronomarker (i.e. the start of the rapid increase in 1970 AD) were selected to validate the 210Pb dating. Sedimentation rates derived from different models were validated using historical data including lake area, arable land area, sediment discharge and reservoir volume in the Yangtze basin. The SCP-corrected CRS (constant rate of supply) model performs better than other models, based on validation using historical documents in the Yangtze basin. -
Diatom Community Succession and Nutrient Evolution Recorded from a Sediment Core of the Longgan Lake, a Large Shallow Lake in East China
第 30 卷 第 6 期 水 生 生 物 学 报 Vol . 30 ,No . 6 2 0 0 6 年 1 1 月 ACTA HYDROBIOLOGICA SINICA Nov. , 2 0 0 6 DIATOM COMMUNITY SUCCESSION AND NUTRIENT EVOLUTION RECORDED FROM A SEDIMENT CORE OF THE LONGGAN LAKE, A LARGE SHALLOW LAKE IN EAST CHINA DONG Xu2Hui and YANG Xiang2Dong ( Nanjing Institute of Geography &Limnology , the Chinese Academy of Sciences , Nanjing 210008 , China) Abstract :The Longgan Lake is a shallow mesotrophic macrophyted2ominated lake. According to the high2resolution diatom research from its sediment core , the diatom community succession was built , and the total phosphorus (TP) and chlorophyll2a (Chl2a) con2 centration were quantitatively reconstructed for the past 2000 years , based on the diatom2TP and diatom2Chla transfer functions. The shifts of diatom assemblages also mirrored the developments of aquatic plant , reflecting the characters of aquatic ecosystem evolution. The inferred epilimnetic TP concentration fluctuated within a small range of 36 to 62μg/ L , indicating the lake remained a relative stable mesotrophic status in the long historical period. The periodical variations of the diatom assemblage and trophic sta2 tus suggest a mitigating function of shallow macrophyte2dominated lakes to nutrient input. The changes of lakesptrophic status donpt linearly respond to the human disturbance in the catchment. The dynamics mechanism of phosphorus in macrophyte2dominated lakes , as inferred from diatoms , will provide a scientific foundation for the prediction of trophic status change in a shallow lake , as well as the lake ecological restoration and management decisions. Key words :Diatom assemblage ; Nutrient ; Quantitative reconstruction ; Aquatic macrophyte ; Longgan Lake CLC number :X172 Document code :A Article ID :100023207(2006) 0620702209 The importance of aquatic vegetation to the ecologi2 on the environment reconstruction based on the sediment cal restoration has been recognized commonly by limnolo2 biomarker such as diatom have made rapid gists and lake managements[1 —4 ] . -

Wildfowl at Risk, 1992
Wildfowl at Risk, 1992 ANDY J. GREEN Brief accounts are given of the status and causes of decline of 50 species and subspecies of wildfowl (.Anseriformes) that are known to be threatened with extinction. A number of changes are made to the earlier list presented in this journal by Kear & Williams (1978), and each taxon is assigned a provisional category of threat in line with recent proposals for the re-evaluation o f IUCN categories made by Mace & Lande (1991). This is a short review of the Anseriform to the list.
