Methodological Basis of Ecological Safety Standards for the Technogenic Impact of Mineral Resource Exploitation

A new methodological approach to the development of biological and technological safety standards for the impact of underground mining on the natural biota is proposed.     

Industrial Cluster Upgradation of Regenerated Resources in Miluo City

With China's rapid economic growth, ecological construction and environmental protection become increasingly important. The regenerated resources industry is an effective way to solve problems, such as resources depletion, energy shortage, and pollution, and it also has strategic importance for the construction of a resource-conserving and environment-friendly society. The regenerated resources industry has been established in Miluo for long time, which includes a recycling system, a processing and utilization system, and a refuse decontamination system. An industrial cluster is in its early stage of development. In order to solve current problems, such as short industrial chain, low processing rate, and low added value, the industrial cluster should be dynamically upgraded by means of technology innovation, chain nucleus creation, and chain extension. We think the industrial cluster of regenerated resources will become a local brand for Miluo, from which other regions or cities will gain valuable experiences and inspirations.

Towards a smallholder hydrology for equitable and sustainable water management

Situations of water scarcity challenge sustainability and threaten small users' access to water. In response to this problem, there has been a search for a method of hydrological analysis that can better represent the needs of small water users. While this search is rooted in the debate favouring a more participatory and inclusive allocation of the resource, it also requires a new focus on smallholder hydrology that can confront the gaps and biases found in current hydrological practices in many countries. This article looks at past hydrological practices and also at results of recent studies, highlighting the perspective of smallholder irrigators in surface water planning in Zimbabwe, and groundwater planning in India. These case studies show that wider social forces, not always best science, drive hydrological practices. However, new frameworks focusing on the water user can emerge for more equitable and sustainable water management.     

人口流动规律及其政策含义

人口流动是人力资源配轩优化的根本创新路径,人口流动的一般规律是:如果流动人口为理性行为选择者,在社会制度安排许可的发展环境下,当不同区域和不同产业间形成比较收益差异,存在着流动收益大于流动成本的潜在和现实的各种获利机会时,就必定驱使人们由低收益领域向高必益领域流动,而且比较收益差异量与流动人口的流速、流量正相关,并必然导致产生收益率及人口分布走向平均化的趋势,社会发展也将获得最优化的人力资源配置结果.其相关政策含义:一是人口流动是流动人口的理性选择;二是切实保障公民的自由流动权利;三是利用比较利益差别促进人口流动;四是降低各种不必要的流动成本和流动风险;五是建构人口流动的有效率社会发展框架.     

中国经济的“阿基米德支点”

资源是经济发展的“阿基米德支点”：世界十大经济国每年能源的生产占全球的６２．１％，消费为７１．０％。重要矿产资源的生产多排在世界前１０名生产国之，外面是消费则多排在１０名之内，且对这些矿产资源的消费量多在９５％以上。     

我国矿产资源态势与对策

我国矿产资源总量大,居世界第3位人均拥有量小,居世界第80位。我国要实现现代化建设的第二步战略目标,矿产资源供需存在着矛盾。为了解决供需矛盾,必须从地质找矿、矿山、一次资源回收、二次资源回收、节能和节材等方面挖掘潜力。改革资源耗费型经济发展旧模式,确立资源节约型经济发展新模式,废止“有水快流”的方针,确立开发与节约并重的方针,是缓解矿产资源供需矛盾的根本途径。具体对策有:(1)依靠科学技术进步开发节约(2)搞好资源进出口贸易取长补短(3)健全法制管理体系依法治矿(4)用好计划机制管好资源和矿山(5)用好市场机制搞活矿业经济。     

The evolution of sustainability

Six separate but related strains of thought have emerged prominently since 1950 in discussions of such phenomena as the interrelationships among rates of population growth, resource use, and pressure on the environment. They are the ecological/carrying capacity root, the resources/environment root, the biosphere root, the critique of technology root, the no growth/slow growth root, and the ecodevelopment root.Each of these strains of thought was fully developed before the word sustainable itself was used. Many of the roots are based on fundamentally opposing assessments of the future of mankind. Many of the roots, such as the ecology/carrying capacity root, are based on physical concepts, and they exclude normative values. Others, such as the ecodevelopment root, include such values as equity, broad participation in governance, and decentralized government.When the word sustainability was first used in 1972 in the context of man's future, in a British book,Blueprint for Survival, normative concepts were prominent. This continued to be the case when the word was first used in 1974 in the United States to justify a no growth economy.Sustainability was first used in a United Nations document in 1978. Normative concepts, encapsulated in the term ecodevelopment, were prominent in the United Nations publications.After about 1978, the term sustainability began to be used not only in technological articles and reports but also in policy documents culminating in the use of the term in the report of the summit meeting of the Group of Seven in 1989.The roots of the term sustainability are so deeply embedded in fundamentally different concepts, each of which has valid claims to validity, that a search for a single definition seems futile. The existence of multiple meaning is tolerable if each analyst describes clearly what he means by sustainability.     

激励相容理论视角下生态公益林补偿对农户的增收效应——以福建三明为例

基于福建三明499户农户的实地调查数据,用倾向得分匹配法测算了生态公益林现金直接补偿和岗位性补偿对农户的增收效应,结果表明：现金直接补偿和岗位性补偿对生态保护和农户增收都是正效应。现金直接补偿对农户增收效应不显著,而岗位性补偿对农户家庭总收入和家庭人均收入的净效应分别达55.4%和57%。进一步研究发现,两种补偿方式对贫困户和非贫困户的增收效应也不尽相同,其中现金直接补偿不利于贫困户增收,而岗位性补偿对不同收入的农户都具有正向显著增收效应。此外,从生态公益林的根本使命出发,可以发现现金直接补偿和岗位性补偿对生态保护的净效应也存在较大差异。故此,科学规划生态补偿方式和补偿标准是实现生态保护和农户增收双重效应的根源所在。
