Currently, in Nairobi County, most air quality monitoring stations use low-cost, inaccurate monitors prone to defects. The study’s objective was to map Nairobi County’s air quality using freely available remotely sensed imagery. The Air Pollution Index (API) formula was used to characterize the air quality from cloud-free Landsat satellite images i.e., Landsat 5 TM, Landsat 7 ETM+, and Landsat 8 OLI from Google Earth Engine. The API values were computed based on vegetation indices namely NDVI, TVI, DVI, and the SWIR1 and NIR bands on the QGIS platform. Qualitative accuracy assessment was done using sample points drawn from residential, industrial, green spaces, and traffic hotspot categories, based on a passive-random sampling technique. In this study, Landsat 5 API imagery for 2010 provided a reliable representation of local conditions but indicated significant pollution in green spaces, with recorded values ranging from -143 to 334. The study found that Landsat 7 API imagery in 2002 showed expected results with the range of values being -55 to 287, while Landsat 8 indicated high pollution levels in Nairobi. The results emphasized the importance of air quality factors in API calibration and the unmatched spatial coverage of satellite observations over ground-based monitoring techniques. The study recommends the recalibration of the API formula for characteristic regions, exploring newer satellite sensors like those onboard Landsat 9 and Sentinel 2, and involving key stakeholders in a discourse to develop a suitable Kenyan air quality index.展开更多

文摘The dynamic characteristics and influencing factors of groundwater level in Qianyang County were analyzed.The results showed that in the south bank of the Qianhe River,the change of groundwater level was mainly affected by precipitation,and the response of the groundwater level to the change of precipitation was one year later.The groundwater level presented a downward trend on the whole.In the north bank of the Qianhe River,the supply source of the groundwater level included precipitation and hydrology,and the groundwater level showed a rising trend on the whole.In the plain area,there was a sudden change in the groundwater level under the control of human activities.In a word,the main factors influencing the groundwater level in various geological conditions were different,so there were great differences between various regions in the dynamic characteristics of the groundwater level in Qianyang County.
文摘Songpan County is a poverty-stricken county in Tibetan areas of Sichuan Province,it belongs to a concentrated poverty-stricken area in China.Through summarizing the specific conditions of multi-level cooperation and complementary advantage poverty alleviation model in Songpan County,this paper analyzed the effect of this model.Through the analysis on the cooperative poverty alleviation model(eastern-western cooperation,provincial targeted assistance,county-wide"four-leading and four-assistance"inner-party assistance,social force"10000 enterprises helping 10000 villages",and"visiting every household and keeping every person busy"),it summarized the implementation and actual results of each level.In addition,it summarized the problems encountered in the implementation process of multi-level cooperation and complementary advantage poverty alleviation model and came up with recommendations.With the aid of this successful multi-level cooperation and complementary advantage poverty alleviation model,Songpan County has achieved a decisive victory in the fight against poverty.At the end of April 2019,the poverty rate in the whole region fell to 0.45%,and it successfully took off the poverty hat.This paper analyzed and refined the specific practice,main achievements,successful experience,implications and reference significance of multi-level cooperation and complementary advantage poverty alleviation model,to provide necessary references for innovation of poverty alleviation model in poverty-stricken Tibetan areas,or even other similar provinces and regions.
文摘From the reform and opening-up policy until now,targeted poverty alleviation in rural areas has always been regarded as a major and arduous task in China,and it strives to achieve the goal of national poverty alleviation by 2020.To firmly win the strong war of overcoming poverty and realize new leap of targeted poverty alleviation in rural areas,Qianshan Village,Ganlu Town,Gongqingcheng City of Jiangxi Province establishes party building projects with rural characteristics by surrounding action of"overcoming poverty and attacking strong poverty"and taking"party building+county sage or worthy"as link.It uses county sage or worthy to drive development of rural industry,and establishes a complete poverty alleviation mechanism,thereby making poor households get rid of poverty,become rich,and embark on the road of well-off society.In this paper,opportunities and challenges in targeted poverty alleviation work of Qianshan Village are analyzed,and corresponding countermeasures and suggestions are proposed.
文摘The basic education in the new period has changed quickly, and all kinds of education departments have strengthened safety education by various approaches;however, the students' safety accidents across the country have still happened frequently, so the people have spontaneously paid attention to and reflected on the students' safety education issue, especially the safety education in the elementary schools where the students are younger. In this paper, the village elementary schools in the counties have been taken as the research object, and the research methods such as documentary method and interview method have been adopted to analyze the current situation of safety education in the village elementary schools in Nanxian County from the aspects such as safety education management, safety education content, safety education awareness, safety education effect and safety education approach.
文摘正Lurking in the rocky hills and valleys of Taihang Range in Northwest Henan Province, a mysterious mountain is covered by changeable clouds and mists almost all year round. This is how it gets its name "Yuntai Mountain", which literally means "the cradle of clouds". Roughly 1,000 years ago, on lunar Sep. 9th the Chongyang Festival, a young man topped the major summit "Evodia Summit" of the Yuntai Moutain. There he saw evodia flourishing all over the hills and valleys, and

文摘As the basic administrative unit of China,counties have grown rapidly in recent years in the context of rapid urbanization,especially for counties located in mountainous areas.The drastic changes in land in mountainous areas can easily cause irreversible damage to the sensitive ecological environment.Through the dual-objective suitability zoning of ecological and construction balance,regional sustainable land use patterns can be realized.In this study,Hantai District in Southern Shaanxi province,China,was chosen as the research area aiming at creating a balance between ecological supply and the development of construction in spatial planning.A dual-objective process evaluation system for ecological protection and construction development was proposed with 15 resistance factors selected from three attributes:natural ecology,economic society,and policy.The minimum resistance surface discrimination methods for ecological land and construction development land were proposed based on vertical space superposition and horizontal minimum cumulative resistance models.Finally,the land in Hantai District was divided into four development grades from the optimal angle of dual goals,i.e.,the construction core zone being 134.56 km^(2),the suitable construction zone 115.77 km2,the ecological buffer zone 153.74 km^(2),and the ecological control zone 151.93 km^(2),using the method combining resistance difference and threshold division.In addition,the development direction of each town under jurisdiction was identified.This study compensates for the deficiency of traditional methods that evaluate land only from a single vertical or horizontal process.
