Typology of Local Construction Materials from the Adamawa and North-West Regions of Cameroon

This article summarizes the different local construction materials observed in two regions of Cameroon (Adamawa and North-West). These raw materials were mapped and evaluated using various methods of investigation (spatial distribution, estimation of reserves, development of a database compatible with geo-referenced maps). The results obtained show three types of local construction materials (vegetal, pedological and geological) with quantitative estimation or distribution. Vegetal local materials include herbaceous savanna with strong dominance of straw in Adamawa region than the North West region. Pedological local construction materials include lateritic soils (ferruginous or clayey), harplan, sandy clay and sandy clay soil while geological local construction materials include volcanic, plutonic and metamorphic rocks. Many sites of these geological materials are suitable for the rock quarry plant. Adamawa region also contains sedimentary rocks constituted by metamorphic conglomerate and sandstones. Two main types of residential homes are constructed with these local construction materials in these regions of Cameroon. These include huts and houses.

Coastal Erosion Along the West Coast of the Taiwan Strait and It’s Influencing Factors

Based on the field surveys and repeated cross-profile observations combined with the comparison of many years’ topog-raphic maps,this study shows the spatial variability and varying patterns of coastal erosion along the west coast of the Taiwan Strait.Regional differentiation in the Meso-Cenozoic coastal tectonics determined the irregular coastline and geological background for large-scale coastal erosion distribution.The intensity of coastal erosion on the west side of the Taiwan Strait is mild in the northern region,severe in the central region and modest in the southern region.The beaches along the coast are mainly backed by dunes,sea-walls or cliffs.The dunes and beaches show periodic erosion and recovery along the coast adjacent to river mouths,while persistent retreat of frontal dunes and beaches tends to occur in other areas.The beach erosion occurs mainly in front of seawalls.Due to the low strength of the unconsolidated sediment the soft cliffs suffer the severest coastline recession.Sea level rise and river sediment discharge reduction are main causes of coastal erosion.Storm surge is common in the studied area and plays an important role in the progress of coastal erosion.Human activities including coastal constructions and sand mining also tend to interfere strongly with the balance of sediment budget in some coastal cells.

Analysis on the Evolution of Regional Economic Disparity in the West Coast of the Strait

With the implementation of reform and opening-up, the overall economy of China has made brilliant achievements; meanwhile, however, the economic disparity has been enlarging among some regions, and between the city and the countryside. The existence and evolution of this kind of economic disparity is concerned with social stability, sustainable development and the construction of harmonious society, which has gradually become the hotspot in social economic development. The West Coast of the Strait (WCS) located in southeast littoral areas is adjacent to the Pearl and Yangtze River Delta in the south and north and faces Taiwan Province in the east. The stability and development of this region has vital political and economic meaning in the social eco-nomic development of our country. It has important theoretical meaning and practical value to research the form, characteristics and evolution of regional economic disparity in the WCS. Based on insightful analysis on existing study results on the WCS, the paper defines the connotation and extension. By a series of abso-lute and comparative relative evaluation indexes and taking the WCS since 1992 as the study object, the paper makes analysis on different scales including three regions, four regions, 20 cities and 152 counties, quantitatively evaluates the level, characteristics and evolution of the regional economic disparity and compares the regional economic disparity on different scales. The main conclu-sions are as follows: the variation trend of the absolute disparity of the whole region is obvious and stable, which has presented an inflating trend; the comparative variation trend on a large scale has waved, The comparative disparity of the three regions in-creased annually from 1992 to around 2000, which had a decreas-ing trend from around 2000 to 2005; the comparative variation trend on a small scale was not stable, which showed an annual increase of four regions, 20 cities and 152 counties from 1992 to around 2003 and a decrease from around 2003 to 2005; there were some correlations between the regional disparity and scale. In other words, the smaller the scale was, the bigger the disparity was.

A Preliminary Analysis of the Tomography Problems in Constructing Bridge and Dike-Road across Taiwan Strait

The construction of the bridge across Taiwan Strait has been studied for a long time and the feasibility study that has attracted attention among scientists and engineers on both sides of the Taiwan Strait[1-4].The key question is whether this bridge and dike-road across Taiwan Strait can be constructed with present technology under such complex geological conditions or not.The results of current researches indicate that the sea floor of the Strait is covered with a horizontal layer composed of both the Pleistocene and the Holocene sandstone and shale with a thickness of about 200~300m.The distance from Pingtan island to China's Xinzhu seashore is 124 km,which might be connected by 4-6 section bridges and 5-7 section of dike-roads,and serve as a best program of the route in the north Strait section.The NE offshore fault along the Fujian coast and that along the west coast of Taiwan,China are the major tectonic lines separated by several NW faults under the upper horizontal layer,these fault 3D feature may be detecting by geo-tomography technique,which can help to deal with the foundation of bridge and dike-road piers.It is judged that the construction of bridge and dike-road beginning from Pingtan to the China's Xinzhu seashore is worth recommendation.In the procedure of the construction of large and high height bridges,must consider the steel structural member be detected by industrial CT technology,and might detect the pier of bridge and dike-road which built by steel tube and reinforced concrete at dike-roads two side,in order to get the hard basement and getting the depth of the pier extend below the sea-floor by the seismic tomographic detection method.

Geotechnical and Geochemical Assessment of Natural Sands in Ahanta West Area, Southwestern Ghana

Geotechnical and geochemical assessment of natural sands being used as fine aggregates for construction purposes in Ahanta West and its Environs was carried out, as well as addressing the environmental problems associated with the exploitation of these sand through the sand winning activities. The results from geotechnical and geochemical tests were bench marked with British, American and Ottawa Standards for testing materials. Representative samples were taken from five different sand winning sites namely, Pompuni, Agona Banso, Fretsi, Tumentu stream and Fretsi river. The geotechnical tests carried out were specific gravity, grain size analysis, moisture content, silt content, permeability test using the constant head permeameter method. The photometer (Hydro Test HT 1000) was used to determine silica, sulphate and chloride concentrations in the sand samples. The oxides for the geochemical analysis were determined using the X-ray fluorescence (XRF) method. The results from the study areas showed that except for Fretsi, the specific gravity, grain size analysis, moisture content, silt content and permeability tests were within the acceptable range for natural sands. Sand samples from Pumponi and Agona Banso had the required Cu and Cc values of being well graded. Sulphate and chloride concentrations were within standards for all the samples;however, silica was low for all the samples. Fe2O3, Al2O3, MnO and Na2O did not meet the Ottawa sand standard. Natural sand is not recommended to be used for construction purposes however, these sands may be treated or blended if it is to be used for construction purposes. There are serious environmental implications for the sand-winning activities in the study areas such as stripped overburden, creation of pits and ponds, increased total suspended solids in surface waters, and destruction of aquatic habitats which needs to be addressed.

The textual introduction about tourism resources has become a remarkable and practical method to publicize its fame and attract tourists at commercial economy time. Meanwhile, these discourses also produce function of discursive construction to tourism resources. Adopting Bhatia＇s multi-perspective model of discourse as theoretical framework, this paper explores how discourses have institutionalized scenery of West Lake, Hangzhou. And through genre analysis of two textual introductions of West Lake written in a different times, this research investigates how discourses play its role in constructing sightseeing resources to appeal to visitors.

海峡两岸生态环境质量差异性评价及港口发展对其的影响

21世纪以来,中国城市化进程不断加快,大量人口涌入沿海地区,海峡两岸经贸活动也越来越频繁,导致脆弱的沿海地区面临较大的生态风险,因此动态监测并评价两岸生态质量对推动两岸城市生态文明建设及促进两岸和谐统一发展具有重要意义。利用谷歌地球引擎(GEE)平台调用2000—2022年Landsat及MODIS数据集,采用主成分分析法构建遥感生态指数的基础上,运用差值分析、空间自相关分析评价两岸生态环境质量的差异性,并在建立两岸主要港口多环缓冲区的基础上探讨港口规模及其周边城市建设对生态环境质量的影响。结果表明:(1)2000—2010年海峡两岸生态环境质量呈“西升东降”的特征,2010—2022年海峡两岸生态环境质量均呈波动上升趋势,新冠疫情期间呈先增后减的趋势,两岸生态环境质量差距逐渐缩小。(2)东岸生态环境质量优于西岸,生态环境质量优良等级区域主要分布在太姥山、玉山山脉等山地区域,较差等级区域主要分布在湖里区和晋江市等城市工业聚集区,2000—2010年生态环境质量等级显著退化的区域主要为东岸的山地区域,2010—2020年等级显著退化的区域主要为西岸的沿海区域。(3)两岸生态环境质量具有较强的空间自相关性,处于山地区域的城市呈高值聚集,西岸的厦漳泉、福州市和莆田市以及东岸近海岸城市呈低值聚集。(4)海峡两岸港口规模及其周边城市建设对生态环境质量的影响具有相似性,离港口距离越远,城市建设用地面积占比越小,生态环境质量越好,班轮运输阶段港口规模越大其周边生态环境质量也越差;直航运输阶段港口规模对生态环境质量的影响减弱并逐步改善。(5)受新冠疫情影响,港口周边生态环境质量稍有转好,且西岸港口规模较大的厦门港和福州港较东岸港口更注重生态建设。研究可为海峡两岸城市生态文明建设提供基础数据支撑,也为生态港口规划提供科学决策依据,同时为促进两岸和谐发展提供助力。

基于沿岸自动气象站的台湾海峡西岸海雾生消过程及特征

2019年4月19日20时—4月26日07时,台湾海峡西岸发生了一次严重海雾事件,通过海西沿海的自动气象站数据进行了海雾生消规律研究。海雾集中于02时至08时发生,其生成时间越接近清晨,持续时间越短。海雾多为本地生成,部分站点海雾为传播而形成且南北海雾之间关联性不大。海雾发生前能见度均快速下降,海雾消亡后能见度快速上升。当海雾生成时,陆表温度–气温LST-T(LST,land surface temperature;T,temperature)在-1.7~2℃之间,陆表温度–露点温度LST-Td(dewpoint temperature,Td)在-1~2.7℃之间,T-Td在0.2~1℃之间,海雾维持阶段相对湿度(relative humility,RH)≥96%。在水汽丰沛的大背景下,海雾生成与发展与风速的关系较为密切,与风向的关系较弱。结合Himawari-8卫星影像与ERA5(European centre for fifth generation of atmospheric reanalysis)再分析资料对本次海雾过程的特征进行了分析。卫星影像给出了本次过程的影响范围和生消特点。环流形势表明,500h Pa上福建处于槽后脊前弱西南气流控制下。850h Pa和925h Pa高度场上均受西南气流的影响,带来了充沛的水汽,根据海气状况分析此次海雾类型为平流雾。
