Research On The Value Theory Of Natural Resources And Pricing Methods

Abstract

This paper analyses the historical reasons that have resulted in the assumption that natural resources have no valuve. As opposed to this assumption, a conception of resource industry is proposed. The paper expounds the basis of the value of resources and explains the significance of the research of resource value theory. It also attempts to determine the relevant factors, methods and formal expressions of pricing resources.

Coordinative Development in Population,Resources and Environment—China's Central Concern in Developing Science and Technology

Abstract

Population, resources and environment constitute the basis for economic and social advances. Their coordinative development is the key factor for the continuous, stable and harmonious development of economy and society. China is a developing country which needs to mobilize the whole society to coordinate among population, resources and environment and to keep publicity and research in pace so as to deepen people's understanding and improve the methods of achieving this coordination.     

四川省人口增长与主要生态资源承载力研究

本文以个体生活资源基本需求为计算单位,探讨四川省主要生态资源能承载多少人口,预测四川省人口发展与生态资源的关系.根据本文给出的计算结果,四川省耕地费源已经饱和,其复耕事较高尚能满足人口需求;牧草场资源超载,面临荒漠化威胁;森林资源较为丰富,能够满足人口发展需求;水资源与人口关系富足有余,但工业污水排放和上游水源保护仍需给予关注.面对这一现实,四川省要进一步推行控制人口增长的生育政策;保护现有耕地资源,发展生态农业;合理规划草场资源,科学发展畜牧业;合理开发森林蕴藏资源,坚持合理采伐;加强水利设施建设,防治水污染,确保水资源可持续利用.     

Towards improved understanding of injury prevention program sustainability

As policy makers and funders have become more concerned with allocating scarce resources effectively, attention to the sustainability of health intervention programs has increased. However, the empirical knowledge base about factors facilitating or working against sustainability remains at an early stage. The aim of this study was to contribute to improved understanding of the conditions under which community-based injury prevention programs are most likely to attain sustainability. Ten Swedish community-based injury prevention programs were analysed with respect to factors that contribute to or detract from program sustainability. All the programs are integrated within existing municipality structures. Data were collected by means of semi-structured telephone interviews with key informants.The results suggested that different factors are interrelated, with no one factor being either primary or by itself sufficient for program sustainability. Financial, human, and relational resources lay the groundwork for the long-term operation of a program. The “integrated” program model appears to facilitate sustainability, but program intensity is vulnerable to changes in the financial status of the municipality and the priority-setting by municipality political decision makers. Sustainability may be compromised if a program becomes too dependent on a few key individuals. In contrast to financial, human, and relational resources, structural resources (e.g., injury surveillance and goals) appeared to have limited influence on sustainability. The programs were sustained with little evidence of effectiveness, resulting in limited feedback about how to improve a program in order to achieve and maintain long-term effectiveness.

Stable-isotope probing of bacterial community for dissolved inorganic carbon utilization in Microcystis aeruginosa-dominated eutrophic water

Dissolved inorganic carbon (DIC) is an important source of carbon in aquatic ecosystems, especially under conditions of increased frequency of cyanobacterial bloom. However, the importance of bacteria in direct or indirect utilization of DIC has been widely overlooked in eutrophic freshwater. To identify the functional bacteria that can actively utilize DIC in eutrophic freshwater during cyanobacterial bloom, stable-isotope probing (SIP) experiments were conducted on eutrophic river water with or without inoculation with cyanobacteria (Microcystis aeruginosa). Our 16S rRNA sequencing results revealed the significance of Betaproteobacteria, with similar relative abundance as Alphaproteobacteria, in the active assimilation of H¹³CO₃^? into their DNA directly or indirectly, which include autotrophic genera Betaproteobacterial ammonia-oxidizing bacteria. Other bacterial groups containing autotrophic members, e.g. Planctomycetes and Nitrospira, also presented higher abundance among free-living bacteria in water without cyanobacteria. Microcystis aggregates showed a preference for some specific bacterial members that may utilize H¹³CO₃^? metabolized by Microcystis as organic matter, e.g. Bacteroidetes (Cytophagales, Sphingobacteriales), and microcystin-degrading bacteria Betaproteobacteria (Paucibacter/Burkholderiaceae). This study provides some valuable information regarding the functional bacteria that can actively utilize DIC in eutrophic freshwater.     

三十年来中国自然资源学会的发展与展望

中国自然资源学会迎来了30周年的大喜日子。论文系统地回顾了30 a来学会的发展历程,分析了存在的主要问题,对未来发展前景进行了展望。30 a来,学会经历了开创、发展和壮大的不同阶段,在为国家经济社会发展提供重要的资源科技支撑的同时,不断丰富资源科学研究的实践经验,并初步建立了中国特色的资源科学理论和方法体系框架。目前,学会已经拥有5 000多名会员、16个专业委员会、3个工作委员会、6个省级学会,成为中国科协下属的全国201个科技社团中的优秀学会之一。通过了国家民政部组织的中国社会组织评估并获得全国社会组织4A 级等级证书;获得了中国科协组织评审的优秀科技社团三等奖。但是,一些根本性问题仍然存在,包括:基本确立了资源科学但尚不牢靠;强调资源综合研究但分支学科分散;国内学术交流活跃但国际交流薄弱。未来学会将继续完善现有的理论方法体系,开拓资源学科研究的新领域;加强世界资源研究和国际合作交流;围绕国民经济应用性强的重大资源科学问题开展决策咨询;狠抓学科建设和资源科技人才培养;搭建"自然资源态势分析与学科发展信息平台"。
