The current level of knowledge of the biophysical situation, human activity and governance in the Bamboutos Mountains does not shed enough light on the dynamics of the vegetation, the socio-economic aspects and ecological op-portunities that are essential for a successful restoration initiative in this degraded landscape of the Bamboutos mountain ecosystems. The objective of the study was to map and analyze the dynamics of land use from Landsat images of 1980, 2000 and 2021. Supervised classification by maximum likelihood was applied and the dynamics were analyzed using area curves and calculations. The cartographic results were used to produce land use maps. The analysis of the land cover dynamics shows that the evolutionary trend of the vegetation formations is essentially regressive for agro-forests and dense forests at −21.20% and −3.62% respectively. The classes that showed a clear progression were bare soil (9.78%), crop land (8.03%), built-up areas (5.19%) and shrubby savannahs and grassland (1.84%). Agriculture, livestock grazing and demographic pres-sure are the main causes of land degradation and mutation of the landscape. The results of this study provide an understanding of the land-use history of this landscape, and a solid basis for planning a restoration initiative. They provide guidance on priority areas and types of restoration intervention from a social, economic and ecological perspective.
目前对竹木山的生物物理状况、人类活动和治理的了解水平不足以说明植被的动态、社会经济方面和生态机会,而这些对于竹木山生态系统退化景观的成功恢复至关重要。该研究的目的是绘制和分析1980年、2000年和2021年陆地卫星图像中的土地利用动态。采用极大似然法进行监督分类,并利用面积曲线和计算方法进行动力学分析。制图结果被用来制作土地利用图。土地覆被动态分析表明,农林林和茂密林的植被形态演化趋势基本为退化,分别为- 21.20%和- 3.62%。依次为裸地(9.78%)、耕地(8.03%)、建成区(5.19%)、灌丛草原和草地(1.84%)。农业、畜牧业和人口压力是土地退化和景观突变的主要原因。本研究的结果提供了对该景观的土地利用历史的理解,并为规划恢复计划提供了坚实的基础。它们从社会、经济和生态的角度为优先恢复区域和干预类型提供指导。

Taking the ground cover plants of seven forest parks in Guangzhou as the research object, a total of 79 quadrats were set up, and the frequency of plant occurrences in the quadrats was counted. It belongs to 58 families and 90 ge-nera, including 41 species of herbs, belonging to 25 families and 39 genera; 54 species of woody plants, belonging to 34 families and 47 genera; 1 species of vines, belonging to 1 family and 1 genus; 3 species of ferns, belonging to 3 families and 3 species. The frequency of plant appearance showed that the ground cover in Guangzhou Park was dominated by herbs, with more woody plants and fewer ferns and vines. Herbaceous plants are mainly foliage plants, and there are few coleus plants; there are more coleus plants in woody plants. There are various types of ornamental plants, flexible plant collocation, and rich landscaping levels. Provide data reference for the application of ground cover plants in urban park green space landscape construction.

Forests provide diverse co-benefits, including livelihoods enhancement, poverty alleviation, and biodiversity conservation and ecosystem services such as climate mitigation. Consequently, Ghana has embraced several global, regional, national, and local forest policy interventions to safeguard its forest resources’ sustainable management. However, the forest policy interventions have not adequately addressed the co-benefits issues of forest resources leading to several forest illegalities that drive forest resources degradation and loss. These forest policies and interventions on the ground primarily favour carbon stocks enhancement and sequestration activities for carbon mitigation purposes compared to the benefits, access and rights that forest-dependent people and communities are supposed to derive from forest resources. These perceived injustices in the access and distribution of forest resources have culminated into all forms of forest illegalities driving Ghana’s forest resources into massive degradation and loss. Currently, Ghana is experiencing a 2% rate of annual deforestation and forest degradation, which translates into approximately 135,000 ha/year of forest cover loss due to anthropogenic causes. Our review is based on relevant and critical forest documents, and scientific peer-reviewed papers on Ghana’s forest policy interventions and dynamics recently published. The information gathered enabled us to highlight the perceived injustices in the forest policy interventions and their effects on forest resources. Unjust forest resources sharing and distribution are critical drivers of forest resources degradation and loss. We thus offer lessons for remedying the unfair distribution and injustices to promote equitable forest resources rights and benefit access to local forest-dependent people. It is expected that this review will offer and assist forest policy, intervention spatial and other planners and designers to find a possible way forward to avoid nature degradation, including biodiversity loss, to resolve perceived injustices in the forestry sector, to use adequate all ecosystem services provided by forests as well as to promote local livelihood and sustainability.
森林提供了多种共同利益,包括改善生计、减轻贫困、生物多样性保护和气候缓解等生态系统服务。因此,加纳采取了几项全球、区域、国家和地方森林政策干预措施,以保障其森林资源的可持续管理。然而,森林政策干预措施没有充分解决森林资源的共同利益问题,导致了一些森林违法行为,导致森林资源退化和损失。与依赖森林的人民和社区本应从森林资源中获得的利益、获取途径和权利相比,这些森林政策和实地干预措施主要有利于为减少碳排放而加强碳储存和固存活动。这些被认为在获取和分配森林资源方面存在的不公正现象最终导致了各种形式的森林非法行为,使加纳的森林资源陷入大规模退化和损失。目前,加纳每年的森林砍伐和退化率为2%,这意味着由于人为原因,每年约有135000公顷的森林覆盖损失。我们的审查基于相关和关键的森林文件,以及最近发表的关于加纳森林政策干预和动态的同行评审科学论文。收集到的信息使我们能够强调森林政策干预措施中的不公正现象及其对森林资源的影响。不公正的森林资源共享和分配是森林资源退化和损失的关键驱动因素。因此,我们为纠正不公平的分配和不公正现象提供了经验教训,以促进公平的森林资源权利,并使当地依赖森林的人受益。预计这项审查将为森林政策、干预空间和其他规划者和设计者提供并协助他们找到一条可能的前进道路,以避免自然退化,包括生物多样性丧失,解决林业部门的不公正现象,利用森林提供的充分的全生态系统服务,并促进当地的生计和可持续性。

This study of the impact of heart rot of Pericopsis elata on logging yield was conducted in Libongo, in three logging concessions of the Societe d'Exploitation Forestiere et Agricole du Cameroun (SEFAC). An inventory of 92 P. elata stumps in four Annual Cutting Areas (AACs) divided among three Forest Management Units (FMUs) distinguished by Minimum Operating Diameter (MOD) revealed that 22 stumps were rotten. Decay was visible on stumps with a diameter of more than 100 cm with a frequency of occurrence of 23.91%, a percentage of abandonment of 55.20% and a yield of 44.79%. The most important economic loss was revealed on 9 abandoned whole logs that cumulated a volume of 145.547 m3. The correlation between the diameter of the stumps and that of the decay gives a coefficient or correlation rate r = 0.31. The MOD for P. elata could be 80 cm and covers the biological risk class. The results indicate that P. elata shows an increasing gradient of decay rate with increasing tree diameter, resulting in a loss of material for larger diameter trees, and consequently a decrease in material yield at processing.
本研究是在喀麦隆林业和农业开发协会(SEFAC)的三个采伐区Libongo进行的,研究了周参心腐病对伐木产量的影响。在以最小作业直径(MOD)划分为3个森林管理单位(FMUs)的4个年度采伐区(AACs)内,对92个白杨树桩进行了清查,结果显示22个树桩腐烂。在直径大于100 cm的树桩上可见腐殖,腐殖率为23.91%,弃殖率为55.20%,产率为44.79%。最重要的经济损失是9根废弃的整根原木,累计体积为145.547 m3。树桩直径与衰变直径之间的相关系数或相关率r = 0.31。白桦的MOD可达80 cm,覆盖了生物风险等级。结果表明,随着树径的增加,白杨的衰减速率呈递增的梯度,导致大直径树的材料损失,从而导致加工时材料产量的下降。

Spatio-Temporal Dynamic of Land Use in the Dja-Odzala-Minkébé Landscape between Cameroon, Congo and Gabon: Influence on the Evolution of Forest Cover in a Context of Cross-Border Cooperation 喀麦隆-刚果-加蓬dja - odzala - mink<s:1>景观土地利用时空动态:跨境合作背景下森林覆盖演变的影响

This study is being carried out in the cross-border area of the tri-national Dja-Odzala-Minkebe (TRIDOM), subject of a cooperation agreement between Cameroon, Congo and Gabon in 2005. The purpose of this study is to analyze the dynamics of changes in land use in the context of cross-border cooperation. Geographic information systems and remote sensing were used to produce the various land use maps. For this purpose, the MERIS satellite images for the periods 1992, 2005 and 2018 were used. The exploration of the different images and the field visits made it possible to identify the following six land use classes: dense forests, degraded/deforested forests, savannas, swamp forests, buildings and bare soils, water surfaces. It emerges that the TRIDOM landscape is mainly occupied by dense forests which represent 97.02%, 96.72% and 96.52% respectively in 1992, 2005 and 2018. Then, degraded/deforested forests and savannas which would correspond to cultivation areas and fallow land only represent respectively 1.06% and 0.68% of the landscape in 1992. This proportion in 2005 is respectively 1.22% and 0.77%, whereas in 2018, it is respectively 1.36% and 0.81% of the massif. The landscape of TRIDOM has not experienced any significant land use change during the period after the signing of the cooperation agreement. Historical rates of deforestation are low during the period under study. They are estimated at 0.042% and 0.030% respectively for the period 1992-2005 and the period 2005-2018. These low rates of deforestation seem to be due to the measures taken to secure and sustainably manage the massif taken by the three countries, the low population density in this area and the still difficult level of accessibility of a large part of the massif.
这项研究正在三国Dja-Odzala-Minkebe (TRIDOM)的跨境地区进行,该地区是2005年喀麦隆、刚果和加蓬之间一项合作协议的主题。本研究的目的是分析跨境合作背景下土地利用变化的动态。利用地理信息系统和遥感技术制作各种土地利用地图。为此,使用了1992年、2005年和2018年期间的MERIS卫星图像。通过对不同图像的探索和实地考察,可以确定以下六种土地使用类别:茂密森林、退化/毁林森林、稀树草原、沼泽森林、建筑物和裸露的土壤、水面。结果表明,1992年、2005年和2018年TRIDOM景观以茂密森林为主,占比分别为97.02%、96.72%和96.52%。1992年,退化/毁林的森林和稀树草原分别只占耕地和休耕地的1.06%和0.68%。2005年这一比例分别为1.22%和0.77%,2018年这一比例分别为1.36%和0.81%。在合作协议签署后的一段时间内,TRIDOM的景观没有发生任何重大的土地利用变化。在研究期间,森林砍伐的历史速度很低。1992-2005年和2005-2018年期间,这一比例分别为0.042%和0.030%。这些低森林砍伐率似乎是由于这三个国家为保护和可持续管理该地块而采取的措施,该地区的人口密度低,以及该地块的大部分地区仍然难以进入。

The belowground biomass is represented by coarse and fine roots. Concentrated in the superficial horizons of the soil, the fine roots play a crucial role in the functioning of a forest ecosystem. However, studies on their dynamics in natural forests are almost non-existent in the Republic of Congo. Here, we estimated the biomass, production, turnover and fine root lifespan of two forest strata of a semi-deciduous forest: the Gilbertiodendron dewevrei (De Wild.) J. Leonard forest (GF) and the mixed forest (MF) of land. The ingrowth cores method was used to estimate the biomass, production, turnover and lifespan of fine roots. The results of this study revealed that the biomass, production and fine root turnover of the two forest strata studied significantly decreased with increasing soil depth, with an increase in lifespan. The annual fine root biomass of GF (2284.50 ± 37.62  and 1034.61 ± 14.52 ) was slightly lower than that of MF (2430.07 ± 40.68  and 1043.10 ± 11.75 ) in the 0-15 cm and 15-30 cm horizons, respectively. The annual production of fine roots from these latter horizons was respectively 1300.19 ± 32.17  and 539.18 ± 11.55  in GF and 1362.24 ± 39.59  and 492.95 ± 14.38  in the MF. Root turnover was higher in the GF (1.68 ± 0.05  and 1.35 ± 0.03 ) than in the MF (1.57 ± 0.05  and 1.13 ± 0.02 ). The lifespan of fine roots increased with the depth of the soil. The difference in fine root dynamics observed between the forest strata studied was influenced by the Evenness index and the above-ground biomass.
地下生物量以粗根和细根表示。细根集中在土壤的表层,在森林生态系统的运作中发挥着至关重要的作用。然而,在刚果共和国,几乎没有对其在天然林中的动态进行研究。在这里,我们估计了半落叶林的两个森林层的生物量、产量、周转率和细根寿命:Gilbertiodendron dewevrei(De Wild.)J.Leonard森林(GF)和混合森林(MF)。采用内生芯法对细根的生物量、产量、周转率和寿命进行了估算。研究结果表明,随着土壤深度的增加,所研究的两个森林层的生物量、产量和细根周转率显著降低,寿命延长。在0-15cm和15-30cm土层中,GF的年细根生物量(2284.50±37.62和1034.61±14.52)略低于MF的年细根生物量(2430.07±40.68和1043.10±11.75)。后一层的细根年产量在GF中分别为1300.19±32.17和539.18±11.55,在MF中分别为1362.24±39.59和492.95±14.38。根周转率在GF中(1.68±0.05和1.35±0.03)高于MF(1.57±0.05和1.13±0.02)。细根的寿命随着土壤深度的增加而增加。在所研究的森林地层之间观察到的细根动力学差异受到均匀度指数和地上生物量的影响。
