  • 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.

The paper conducted socio-economic metabolism analysis by means of the emergy accounting method coupled with data envelopment analysis and decomposition analysis techniques to assess the sustainability of Qingyang city and its eight sub-region system, as well as to identify the major driving factors of performance change during 2000–2007, to serve as the basis for future policy scenarios. The results indicate that Qingyang greatly depended on non-renewable emergy flows and feedback (purchased) emergy flows, except the two sub-regions, named Huanxian and Huachi, which highly depended on renewable emergy flow. Zhenyuan, Huanxian and Qingcheng were identified as being relatively emergy efficient, and the other five sub-regions have potential to reduce natural resource inputs and waste output to achieve the goal of efficiency.

  • Middle Jurassic Sequence Stratigraphic Characteristics in Longdong Coalfield
    E3S Web of Conferences 118, 01010 (2019) https://doi.org/10.1051/e3sconf/201911801010 ICAEER 2019 Middle Jurassic sequence stratigraphic characteristics in Longdong coalfield Tai Xu1,*, Shuang Li1, Fengfeng Yang1, Jufeng Zhang1, and Xiulan Zhu1 1School of Energy Engineering, Long Dong University, 745000, China Abstract. Stratigraphic sequence contrast and sequence stratigraphic framework are of great significance for the sedimentary phase and sedimentary systems of coal-accumulating basin. In the coal-bearing basin, the variation of the flooding surface controls the migration law of the coal-concentrating centres within the range. Therefore, the sequence comparison work is crucial to find favorable coal-collecting areas. In addition, studying the position of the coal seam in the sequence stratigraphic framework and carrying out the sequence comparison work in the lateral direction can effectively track the change of the position of the coal seam in the sequence stratum and summarize the law of coal seam accumulation and occurrence, which can be better to plan and guide the exploration and development of coal resources in Longdong coalfield. The Longdong area of Gansu Province, including the expanding systems tract. The maximum flood surface areas under the jurisdiction of Pingliang City and and the sequence top boundary is the basin reducing Qingyang City, east of Liupan Mountain, is located in systems tract. The Ordos Basin is a large inland the southwestern part of the Ordos Basin. It is part of the sedimentary basin. It is a large inland basin with a stable Ordos giant Mesozoic basin and is rich in coal resources. tectonic setting formed by the contraction of the North According to the survey, the proven coal resource China Basin after the Indosinian movement.

China’s rapid urbanization has resulted in the acceleration of urban–rural mobility. Moreover, the implementation of the New Urbanization and Rural Revitalization Strategy has demonstrated the prospects of urban–rural integration and development. However, research on rural mobility is mainly focused in the fields of economics and sociology, with insufficient attention paid to spatial mobility. The main purpose of this study is to introduce a new theoretical explanation of the four dimensions of rural mobility based on a complete understanding of the current socio-economic background, namely, network mobility, green mobility, people-oriented mobility, and smart mobility. On this basis, a rural mobility evaluation index system is proposed by attempting to build a synthetic rural mobility index from the four aforementioned dimensions. Qingyang, a typical city in Western China located in the Loess Hilly Region, is taken as an example.

  • Violence Against Women in the Name of Population Control
    “I Don’t Have a Choice over My Own Body” CHRD December 21, 2010 Chinese Human Rights Defenders (CHRD) Web: http://crd-net.org/ Email: [email protected] Promoting human rights and empowering grassroots activism in China “I Don’t Have a Choice over My Own Body” The Chinese Government Must End its Abusive Family Planning Policy Embargoed for release at 1am on December 21, 2010 “I don’t have a choice over my own body. If I don’t insert it [the intrauterine device], I’d be detained,” wrote a woman on an internet forum for mothers.1 “I discover that in China, in this society, women in villages have no human rights. They [local family planning officials] even said that I am under their management, that I do not have a choice, that whatever they say I have to do,”2 wrote another woman on the same forum. This year marked the thirtieth anniversary of China’s family planning policy, often referred to as the “one-child policy.” In recent years, the government has carved out many exceptions to “one-child” aspect of the policy, leading to widespread speculation about its current status and future: Are people still bound by the policy, or can they pay their way out of it and have as many children as they want? Is the government going to loosen the policy, allowing couples to have more than one child? CHRD argues that this focus is misplaced. Though the National Population and Family Planning Law, enacted in 2002, was ostensibly designed to rein in abusive practices associated with the family planning policy, the Chinese government continues to use coercion and violence to implement the policy.3 The family planning policy remains abusive of Chinese citizens’ reproductive rights regardless of the number of children each couple is allowed to have, and will remain so unless the policy in its current form is abolished.

Statistical data show that in Gansu Province, East and West, from 50 at the end of twentieth Century to 1992, a total of 14109 loess landslide are occurred. In recent years, because of the exacerbated economic and social development and population growth, the frequency of the occurrence of geological disasters is increased, causing more and more casualties and property losses [1].
