The eradication of poverty is one of the largest global challenges facing the world. This article examines poverty reduction goals within the framework of Post-2015 Development Agenda and the Sustainable Development Goals(SDGs). It also discusses the relationship between poverty reduction and sustainable development. Poverty reduction and sustainable development are inseparable and poverty reduction is the premise for sustainable development. Furthermore, several key bones of contention on the role of poverty reduction and sustainable development and implications of Post-2015 Development Agenda are also discussed. It concludes that to end poverty and inequality should continuously be given top priority for the Chinese government, because poverty reduction is China's soft power. Meanwhile, new ways of poverty alleviation should be explored and government should make great efforts to create a new partnership for poverty reduction and development. 展开更多

After the founding of the People’s Republic of China, the Chinese people have been struggling against poverty amid national development under the leadership of the Communist Party of China(CPC). Since reform and opening up, in particular, China has planned for and organized development-oriented poverty reduction practices on a broad scale with remarkable achievements and blazed a new path of development-oriented poverty reduction with Chinese characteristics. This path is both an essential component of Chinese socialism and a result of the CPC’s ideological improvement on poverty reduction. Since the 18 th CPC National Congress in 2012, the whole Party, country, and society have been called upon to fight the battle against poverty on a full-scale under the guidance of General Secretary Xi Jinping’s important statements on poverty reduction, unveiling a new stage for China’s development-oriented poverty reduction in the new era. China’s unprecedented poverty reduction achievements have enriched the path of poverty reduction with Chinese characteristics. Xi Jinping’s insightful and coherent statements on poverty reduction represent the latest results of Marxist anti-poverty theories and comprise an essential part of Xi Jinping Thought on Socialism with Chinese Characteristics for the New Era. His guidelines are the basis for the brilliant achievements of China’s poverty reduction endeavors, and will contribute Chinese experience and wisdom to global poverty governance. 展开更多

In order to fabricate dispersion strengthened alloys strengthened by submicron-sized or nano-sized stable particles through casting routes, understanding of the formation process of dispersion strengthening particles in metal melt is of significance. Thus, nano NiO and TiO2 particles were selected as reactant to form in-situ dispersion strengthening oxide particles in Fe20Cr5Al alloy. Nano NiO and TiO2 particle powder was separately dispersed into nano Ni powder first. The loose mixed nano powder was added in Fe20CrSAl alloy melt when pouring the melt into mold. The study shows that nano NiO particles were not as effective as nano TiO2 particles in forming dispersion strengthening Al2O3 particles. The final diameters of dispersion strengthening oxide particles arose from nano TiO2 particles were of submicron. The Brownian collision of particles had caused this coarsening. 展开更多

Looking from the existing research,improving the social capital of the poverty population is an effective way to promote the population quality and the income growth of the poor people. Based on the existing research,with the rural poor households in Sichuan Liangshan as the research object,this article used factor analysis to measure social capital stock,and then analyzed the influence of social capital on the income of the poor peasant households in that region,through the reconstructed production function. The results show that the poor households' social capital has a significant impact on their income level,and the effect degree varies in different income levels. 展开更多

POVERTY is a state that can last indefinitely.A sound,stable,and long-term mechanism is therefore necessary to end it.Such a mechanism decides the process and outcome of the fight against poverty,and is critical for the realization of China’s post-2020 goal of sustainable development in poor areas and reduction of relative poverty.It also lays the foundation for realizing the country’s second centenary goal – building a modern socialist country that is prosperous,strong,democratic,culturally advanced,and harmonious by 2049. 展开更多

Using NCEP reanalysis data,high-altitude and ground observation data,numerical model data,satellite and radar data,formation cause and forecast deviation of an extreme rainstorm process in Changsha urban area at night on June 9,2020 were analyzed.The results showed that(1)the extreme rainstorm process developed near the surface convergence line,with strong localization,short duration and large hourly rainfall intensity.(2)Under the high temperature and high humidity environment,the low-level cold advection and the hot low-pressure system interacted,and the potential con-vective unstable energy was released,and a strong convective weather was formed.(3)The convergence of water vapor in the lower layer and the strong upward movement provided sufficient water vapor for the rainstorm.The low-centroid thunderstorm was the main reason for the extreme rainstorm.(4)The forecast deviation of the numerical model to the low-level shear line and the mesoscale convergence line was an important reason for the forecast deviation of the heavy rainfall area. 展开更多

In Sidi Chennane deposits (Morocco), the phosphatic series is composed of regular interbedded phosphatic and marly limestone layers. Exploitation of the phosphate in these deposits collides frequently with problems bound to the existence, in this series, of sterile bodies qualified as derangements. They cause two kinds of problems: 1) as they are hard, compact and masked by a Quaternary cover, they disturb the exploitation in some yards and give bad reserve calculation;2) even the use of wells and mechanical boreholes did not evidence their delimitation. Our study shows that these bodies can be detected and delimited using ground penetrating radar and electrical resistivity tomography methods. It is based on the acquisition and the interpretation of series tests using these methods carried out above visible sterile bodies in a trench of exploitation in order to have geologically valid information. The article concerns to the analysis of the results and of the proceeding for a possible large geophysics survey. 展开更多
