Stand Diversity and Carbon Stock of a Tropical Forest in the Deng Deng National Park, Cameroon

Tropical rainforests are crucial in maintaining about 70% of the world’s plant and animal biodiversity and are also the highest terrestrial carbon reservoir. This study aimed to determine the tree species composition, structure and carbon stocks of the Deng Deng National Park which is a semi-deciduous tropical forest (plots 1 and 2 and the transition zone to the savannah (plot 3). Plots demarcation and enumeration followed standard protocols for permanent monitoring plots. The inventory of tree species ≥ 2 cm revealed a total of 5523 individuals of 64 species in 53 genera belonging to 26 families with plot 2 having the highest (2135 individuals/ha) and plot 3 the least (1291 individuals/ha). Tabernaemontana crassa was the most important tree species in the tropical forest and Lecythis idatimon in the savannah. Basal area was highest in the tropical forest and least in the savannah. The diameter distribution of trees in all forest types displayed a reverse J-pattern. Aboveground biomass was highest in the tropical forest (530.2 ± 66.4 t·C/ha) and least in the savannah (184.3 ± 20.1 t·C/ha). The carbon stock of the above ground biomass was twice as much as that of the below ground biomass, soil organic matter and litter. The total carbon stock estimated in all pools was 278.75 t·C/ha. The study site was poor in plant diversity, biomass and carbon stock, indicating a disturbed site with the absence of large trees and undergoing natural regeneration. This underlines an urgent need for efficient restoration management practices.

在壮语中,Deng(te:η)字意蕴丰富,用法灵活,可起到事件因果关系的连接作用,构成事件因果关系句。通过实验方法,收集到72个deng字句,其中45句是事件因果关系句。可见其在壮语deng字句中比较突显。认知语法中的意象、注意、背景和突显等理论可对此类句型进行解读。研究发现,壮语deng字句具以下特征:1) Deng字语义蕴含丰富,但"偶发性、遭受义"突显;2)因意象与注意都具有选择性,思维方式不同,语言结构各异而使壮语中deng字因果关系句的表征与英语有差异;3)使因事件前景化,结果事件背景化;4) Deng字在因果关系句中起到连接使因事件与结果事件的作用,Deng字前后的使因事件与结果事件关系最密切、最直接。

Logging identification method of depositional facies in Sinian Dengying Formation of the Sichuan Basin

The sedimentary facies/microfacies,which can be correlated with well logs,determine reservoir quality and hydrocarbon productivity in carbonate rocks.The identification and evaluation of sedimentary facies/microfacies using well logs are very important in order to effectively guide the exploration and development of oil and gas.Previous carbonate facies/microfacies identification methods based on conventional well log data often exist multiple solutions.This paper presents a new method of facies/microfacies identification based on core-conventional logs-electrical image log-geological model,and the method is applied in the fourth member of the Dengying Formation(Deng 4)in the Gaoshiti-Moxi area of the Sichuan Basin.Firstly,core data are used to calibrate different types of facies/microfacies,with the aim to systematically clarify the conventional and electrical image log responses for each type of facies/microfacies.Secondly,through the pair wise correlation analysis of conventional logs,GR,RT and CNL,are selected as sensitive curves to establish the microfacies discrimination criteria separately.Thirdly,five well logging response models and identification charts of facies/microfacies are established based on electrical image log.The sedimentary microfacies of 60 exploratory wells was analyzed individually through this method,and the microfacies maps of 4 layers of the Deng 4 Member were compiled,and the plane distribution of microfacies in the Gaoshiti-Moxi area of the Sichuan Basin was depicted.The comparative analysis of oil testing or production results of wells reveals three most favorable types of microfacies and they include algal psammitic shoal,algal agglutinate mound,and algal stromatolite mound,which provide a reliable technical support to the exploration,development and well deployment in the study area.

Trial Study on DENG Tie-tao's Coronary Heart Disease Capsules in Improving Patients' Quality of Life

Objective： To assess the efficacy of the Coronary Heart Disease （CHD） Capsules worked out by Prof. Deng -- in improving quality of life of CHD patients of qi deficiency with phlegm and blood stasis syndrome. Method： According to the WHO＇s diagnosis criteria of CHD, a total of 93 stable angina patients were divided into 3 groups using the single blinded method. The groups were evenly distributed into CHD Capsule treated group （CHDC）, isosorbide dinitrate control group （ID）, and Compound Prescription Danshen Droplet Pills control group （CPDDP）. Two courses of treatment lasting for 6 months were given. During the courses of treatment, the following parameters were observed： clinical symptoms of angina pectoris, ECG change, treadmill exercise test, 36 items in short form of health survey （SF-36） and Seattle Angina Questionnaire （SAQ） scale. Results： After 6 months of treatment, all the three groups showed good curative effect in angina pectoris, ECG and treadmill exercise test, differences between them had no statistical significance. The CHDC group showed a better result in nitro-glycerine stopping or alleviation rate and in improving symptoms than the other groups （P〈0.05）. The general health, vitality, role-emotional, mental health and reported health transition in the CHDC group were significantly better than those in the control groups （P〈 0.05）. The scores in physiological functioningrole, physiological function and pain alleviation were not different among the three groups. Conclusion. Prof. DENG Tie-tao＇s CHDC is effective in treating CHD with qi deficiency, phlegm and blood stasis and also in improving the quality of life. CHDC is more suitable to be used in long-term treatment than isosorbide dinitrate. The SF-36 and SAQ can be used to appraise the curative effect of traditional Chinese medicine agents for CHD angina pectoris.

Floristic diversity and carbon stocks in the periphery of Deng–Deng National Park,Eastern Cameroon

Carbon is continuously being removed from the atmosphere by photosynthesis and stored in carbon pools(live,dead,and soil carbon)of forest ecosystems.However,carbon stock in dead wood and of trees with diameters at breast height(dbh)between 5 and 10 cm is often not considered in many studies carried out in the Congo Basin Forest.The relationship between tree diversity,life-forms and carbon stocks has received little attention.This study was carried out on the outskirts of Deng Deng National Park(DDNP)to determine tree diversity(dominant families,species richness and Shannon index),assess carbon stocks in the five carbon compartments(living tree,understory,fine roots,dead wood and litter)as well as to analyze the relationship between(1)carbon stocks and tree diversity;and,(2)between carbon stock and life-forms.The Shannon index of trees≥10 cm dbh ranged from 2.6 in riparian forest to 4.3 in secondary forest;and for the tree between 5 and 10 cm,it ranged to 1.56 in riparian forest to 3.68 in the secondary forest.The study site housed 16 species,7 genera and 3 families which are only found in trees of dbh between 5 and 10 cm.The average total carbon stock of the five compartments varied from 200.1 t ha-1 in forest residues to 439.1 t ha-1 in secondary forest.Dead wood carbon stock varied from 1.2 t ha-1 in riparian forests to 12.51t ha-1 in agroforests.The above ground carbon stocks for trees with diameter between 5 and 10 cm varied from 0.7 t ha-1 in young fallow fields to 5.02 t ha-1 in old secondary forests.This study reveals a low but positive correlation between species richness and total carbon stocks,as well as a significant positive relationship between life-forms and total carbon stocks.The findings highlight the need for more data concerning carbon content of dead wood,carbon of trees≥5 cm<10 cm dbh and the relationship between carbon stocks and tree diversity from other areas of the Congo Basin for a good understanding of the contribution of tropical forests to climate change mitigation.
