The solitary elderly people in rural areas are not only an important part of the rural population,but also an important issue that can not be ignored in the battle to get rid of poverty. In recent years,according to the working thinking of ' accurate statistics,scientific arrangement,classified implementation,and rapid progress',Xundian County has gone through joint exploration and practice at the county and township levels,and has found out the path of work of ' Five Batches Project' to solve the problem of poverty alleviation for the solitary elderly people and make them live in their own homes. This has effectively solved the problem of safe and stable housing for 4 443 solitary elderly people in the county. It has found a new way to solve the housing problem of the solitary elderly people. At the end of 2017,the incidence of poverty in the county dropped to 0. 35%,and it was successfully listed as one of the first counties in Yunnan Province to get rid of poverty. Based on field research and interviews,this paper analyzes and summarizes the concrete methods,main achievements,practical experience,lessons and reference of the poverty alleviation model of ' Five Batches Project' in Xundian County to solve the problem of housing for the elderly,in order to provide necessary reference for the poor counties in Yunnan Province and other similar provinces( cities,autonomous regions) to solve the problem of housing for ' solitary elderly people' in Yunnan Province. 展开更多

The poverty alleviation through education is one of the important ways to get rid of poverty accurately in poor areas. Located in the high mountains and deep valleys along the Jinsha River, Luquan Yi and Miao Autonomous County in Yunnan Province is one of the key counties in poverty alleviation and development work in China with a wide range of poverty and deep poverty. To enable children in poor areas to receive a good education is not only an important task of poverty alleviation and development, but also an important way to block the intergenerational transmission of poverty. Because of the complexity and difference of geography, history and culture, and the particularity and diversity of educational development appeal, it is often difficult to carry out poverty alleviation through education. Poor counties develop well education so that poor counties have new achievements. In recent years, Luquan County has adhered to the concept of "vigorously developing education" by making every effort to create a characteristic project with education to help the poor, and strived to achieve the "six solutions" so that every child can enjoy quality and fair education, and ensure that "they can get in, stay and learn well". This shows the new look of Miao and Yi mountains in the new era. This paper analyzes and summarizes the specific methods and effects, characteristics and bright spots of accurately building the model of "well education in poor county" in this county, as well as the experience gained, and the lessons, in order to provide the necessary reference for the poor counties in Yunnan Province and other similar provinces (municipalities, autonomous regions) to carry out rural poverty alleviation by education. 展开更多

Carrying out health poverty alleviation and ensuring the security of basic medical care for the poor are important contents for China to implement the strategy of targeted poverty alleviation and win the battle to get rid of poverty. Xundian Hui and Yi Autonomous County in Yunnan Province is a national poor county integrating ' nationality,poverty,mountainous area and old revolutionary base area'. In recent years,based on the actual situation,Xundian County has explored an effective way of health poverty alleviation. It has effectively prevented the phenomenon of poverty caused by illness and returning to poverty due to illness,and effectively ensured that Xundian County has successfully achieved the goal of getting rid of poverty. Xundian County finally got rid of the shadow of ' poverty' for more than 30 years to become one of the first batch of counties in Yunnan Province to get rid of poverty. This paper makes great efforts to analyze and summarize the specific methods,main achievements,successful experience,lessons and reference about health poverty alleviation in Xundian County. At the same time,it also studies and analyzes the main problems existing in the model,and puts forward the corresponding measures and suggestions,in order to provide a reference for health poverty alleviation in other poor areas. 展开更多

Pendjari Biosphere Reserve(PBR),a primary component of the W-Arly-Pendjari transboundary biosphere reserve,represents the largest intact wild ecosystem and pristine biodiversity spot in West Africa.This savannah ecosystem has long been affected by fire,which is the main ecological driver for the annual rhythm of life in the reserve.Understanding the fire distribution patterns will help to improve its management plan in the region.This study explores the fire regime in the PRB during 2001–2021 in terms of burned area,seasonality,fire frequency,and mean fire return interval(MFRI)by analysing moderate resolution imaging spectroradiometer(MODIS)burned area product.Results indicated that the fire season in the PBR extends from October to May with a peak in early dry season(November–December).The last two fire seasons(2019–2020 and 2020–2021)recorded the highest areas burned in the PBR out of the twenty fire seasons studied.During the twenty years period,8.2%of the reserve burned every 10–11 months and 11.5%burned annually.The largest part of the reserve burned every one to two years(63.1%),while 8.3%burned every two to four years,5.8%burned every four to ten years,and 1.9%burned every ten to twenty years.Only 1.3%of the entire area did not fire during the whole study period.Fire returned to a particular site every 1.39 a and the annual percentage of area burned in the PBR was 71.9%.The MFRI(MFRI<2.00 a)was low in grasslands,shrub savannah,tree savannah,woodland savannah,and rock vegetation.Fire regime must be maintained to preserve the integrity of the PBR.In this context,we suggest applying early fire in tree and woodland savannahs to lower grass height,and late dry season fires every two to three years in shrub savannah to limit the expansion of shrubs and bushes.We propose a laissez-faire system in areas in woodland savannah where the fire frequency is sufficient to allow tree growth.Our findings highlight the utility of remote sensing in defining the geographical and temporal patterns of fire in the PBR and could help to manage this important fire prone area. 展开更多

Social capital in the form of social resources or social networks is one of the most important livelihood capital of farmers, which can increase the labor productivity of poor households and increase income. It is important to explore the reasons underlying the livelihood strategy choices of farmers from the perspective of social capital under China’s rural revitalization strategy. In this study, the Liangshan Yi Autonomous Prefecture, a povertystricken mountainous area in southwestern China, was selected as the case study area, and multivariable linear regression models were constructed to analyze the influence of social capital on livelihood strategies.The results are as follows:(1) Individual social capital had a positive effect on non-agricultural livelihood strategies. On average, with a one-unit increase in individual social capital, the ratio of farmers’ nonagricultural income to total productive income(Income_Rto) increased by 0.002% and 0.062%,respectively. Collective social capital, with the Peasant Economic Cooperation Organization(PECO) as the carrier, had a negative effect on the non-agricultural livelihood strategies of farmers;on average, with a oneunit increase in PECO, Income_Rto decreased by approximately 0.053%. However, this effect was only significant in the river valley area.(2) The income differences among the different livelihood strategy types were explained by the livelihood strategy choices of farmers. As non-agricultural work can bring more benefits, the labor force exhibited one-way migration from villages to cities, resulting in a lack of the subject of rural revitalization. It is necessary to implement effective measures to highlight the role of PECO in increasing agricultural income for farmers. Finally,based on the above conclusions,policy recommendations with respect to livelihood transformation of farmers and rural sustainable development are discussed. 展开更多

Since the founding of the People’s Republic of China in 1949,China’s per capita education level has risen from less than two years to 9.91 years.However,as the province with the lowest per capita education level in China,Tibet has only reached the level of 6.75 years per capita.This illustrates the worrying educational inequality that still exists between China’s poorer and more developed regions.This educational inequality can also be expressed by the Gini coefficient of education.In order to eliminate this educational inequality,the Chinese government has made great efforts.The Chinese government has expanded the demand for education through the right incentive system and the nine-year compulsory education law.On the other hand,the Chinese government directly or indirectly grants subsidies to education suppliers and demanders to achieve the purpose of increasing education output.Based on the positive externality of education itself,the Chinese government attaches great importance to the cultivation of human resources for offspring,and hopes to transform China’s quantity-based demographic dividend into quality-based demographic dividend,and finally realize sustained economic growth.We believe that some education-related policies promulgated by China have indeed reduced educational inequality in poor areas to some extent,but there is still potential for progress in further addressing educational inequality in poor areas by the Chinese government. 展开更多

Russia’s invasion of Ukraine has significantly altered the pattern of alliances and geopolitical balances on the European continent to such an extent that countries like Finland and Sweden that have traditionally remained neutral are now applying to join the North Atlantic Treaty Organization(NATO).These two countries fear that Russia,which is currently trying to reposition itself,could try in the near future to invade these two Nordic countries to prevent the West(European Union,United Kingdom,and United States)from increasing its military presence and its military force in the Scandinavian peninsula and in the Baltic Sea.The enlargement that the European Union(EU)has carried out since the 1990s,and that has also meant the expansion of NATO,has been viewed with great concern by the government of Vladimir Putin,who considers that the United States and the European Union did not fulfill their commitment to former Russian President Mikhail Gorbachev to respect the sphere of influence of the former Union of Soviet Socialist Republics(USSR).Within the framework of this geopolitical confrontation,Helsinki and Stockholm do not want to run the risk of being invaded by the Russian army,which is why they seek to take advantage of the principle of collective security that NATO membership would grant them. 展开更多

The West Kunlun ore-forming belt is located between the northwestern Qinghai-Tibet Plateau and southwestern Tarim Basin. It situated between the Paleo-Asian Tectonic Domain and Tethyan Tectonic Domain. It is an important component of the giant tectonic belt in central China (the Kunlun-Qilian-Qinling Tectonic Belt or the Central Orogenic Belt). Many known ore-forming belts such as the Kunlun-Qilian Qinling ore-forming zone, Sanjiang (or Three river) ore-forming zone, Central Asian ore-forming zone, etc. pass through the West Kunlun area. Three ore-forming zones and seven ore-forming subzones were classified, and eighteen mineralization areas were marked. It is indicated that the West Kunlun area is one of the most favorable region for finding out large and superlarge ore deposits. 展开更多

In this paper, based on the observational data of 1995 in the Chinese Antarctic Great Wall Station the snowstorm is studied synoptically. It is found that there are two kinds of snowstorms with different physical characteristics and that the happening of snowstorm is always accompanied by a near-ground level inversion layer. The function of the inversion layer is analyzed, too. It is indicated that the strong ESE-wind type snowstorm is mainly caused by katabatic wind and gradient wind together. This idea is new and different from the general concept that there is no katabatic wind in the western Antarctic area. 展开更多

Hydrologic conditions of the ground water of the Quaternary aquifer in west Ismailia area, Egypt, were characterized based on new hydrologic data collected in 2017. The Quaternary aquifer consists of alluvial deposits. The grain size distribution results indicate that the major part of the aquifer deposits is formed of medium to coarse grained sand with medium uniformity coefficients ranging between 2.5 and 10. They also reflect the heterogeneity, anisotropy and high productivity of the aquifer. The estimated aquifer parameters range from 29% to 41% for total porosity, from 18.71 m/day to 63.95 m/day for horizontal hydraulic conductivity, from 8.94 m/day to 61.6 m/day for vertical hydraulic conductivity, from 1.01 to 4.27 for anisotropy and from 1870 m2/day to 6549 m2/day for transmissivity. The ground water flows mainly from the north and northeast recharge sources (Ismailia and El Manaief canals) and from the south recharge area (Miocene aquifer), with an average hydraulic gradient of 0.00438. The recharge rate to the aquifer (from the southern area) and the Darcy’s velocity of ground water are estimated to be 447 × 106 m3/year and 0.203 m/day (on average), respectively. A great change in the hydrologic setting of the aquifer is occurred during the period of 1992-2017, where the groundwater flow has changed during that period. The aquifer contains fresh to saline water. An oxidizing (alkaline) environment is reported for the aquifer, as revealed from the relationship between the redox potential (185 - 836 mV) and pH (5.2 - 7.5 standard units). This indicated the capability of ground water to dissolve heavy metals associated to rock-forming minerals. A wide variation in the concentrations of total dissolved solids (320 - 7385 mg/l) and dissolved oxygen (2.13 - 8.4 mg/l) in the Quaternary aquifer is observed, reflecting the local variation of the environmental and geologic conditions and indicating the influence of different recharge sources. 展开更多

Fragrant camphor tree is the city tree of Hangzhou which takes a large proportion of the ancient trees in Hangzhou City. Recently, with the free open of the attractions around the West Lake and the implementation of the comprehensive pro- ject for protecting the West Lake, a part of ancient fragrant camphor trees are fac- ing problems such as altered living conditons. Some of them are showing a decline in growth vigor or even close to death, which will produce extremely negative influ- ences on the maintaining and sustainable development of the West Lake Scenic Area if without any timely measures for the rescue and rejuvenation of the trees. Therefore, strengthening the protection and management of ancient fragrant camphor trees at the West Lake Scenic Area and carrying out researches on the procedure for diagnosing the reasons for the growth recession of the ancient fragrant camphor trees at the West Lake Scenic Area are of great significance for the future protec- tion and rejuvenation of the ancient trees around the West Lake. The factors influ- encing the growth of ancient trees and indexes for judging the growth condition were listed and the reasons for the growth recession were systematically summa- rized in this paper. In addition, measures for the rejuvenation of the ancient fragrant camphor trees were also simply discussed. 展开更多

Based on the reanalysis data of monthly mean global SST and wind from the NCEP/NCAR and the observation data of rain seasons in 124 stations of Yunnan province from 1961 to 2006, we applied the analytical methods of correlation analysis and composite analysis and a significance testing method to two sets of samples of average differences. The goal is to investigate into the influence of the Southern Hemispheric(SH) SST on the summer precipitation in Yunnan from January to May so as to identify the key time and marine regions. Physical mechanisms are obtained by analyzing the influence of sea level wind and the key marine regions on the precipitation during Yunnan's rain season.Results show that there is indeed significant relationship between the SST in SH and summer precipitation in Yunnan.The key areas for influencing the summer precipitation are mainly distributed in a region called "West Wind Drift" in the SH, including the Southeast Indian, southern Australia, west coast of eastern Pacific off Chile, Peru and the southwest Atlantic Magellan. Besides, the most significant marine region is the west coast of Chile and Peru(cold-current areas of the eastern Pacific). Diagnostic analysis results also showed that monsoons in the Bay of Bengal, a cross-equatorial flow in the Indian Ocean near the equator and southwest monsoon in India weaken during the warm phase of the Peruvian cold current in the eastern Pacific. Otherwise, they strengthen. 展开更多

This paper describes results of the fluxes of momentum , sensible heat and latent heat for the West Pacific Tropical Ocean Area ( 127 ° E - 150 ° E , 5 ° N -3 ° S ). The data were collected by the small tethered balloon sounding system over this ocean area including 6 continuous stations (140 ° E. 0 ° ; 145 ° E, 0 ° ; 150 ° E, 0 ° ; 140° E, 5 ° N; 145 ° E, 5° N and 150 ° E, 5 ° N) from 11 October to 15 December, 1986 . These fluxes were calculated by the semiempirical flux-profile relationships of Monin-Obukhov similarity theory using these observed data. The results show that for this tropical ocean area the drag coefficient CD is equal to (1.53 ± 0.25) × 10 3 and the daily mean latent flux Hl is greater than its daily mean sensible flux HV by a factor of about 9. 展开更多
