本文研究了米达河(南纬3°20′,东经40°00′)两个红树林森林地区(乌永博和基雷普维)带状横断面的红树林植被的结构和恢复型式。根据种类的重要价值,米达河的优势红树林树种为角果木和红茄冬。树的密度从基雷普维的1197棵/hm^2到乌永博的1585棵/hm^2不等,前者的平均树高要比后者的高。两地的红树林大小级的结构表明,小的树要比大的树多。成年树和幼树的空间分布模式在两个地点变化很大,前者表现为接近于均匀的型式(Morisita的指数I_0<<1),但后者有随机分布的趋势(I_0=1)。本文研究表明,未管理的但已开采的红树林不一定会消失,但质量上却从当地受欢迎的红茄冬变化到不太受欢迎的角果木。虽然这种变化对红树林生态功能的影响尚未估算,但红树林的经济功能却明显地变弱了。

Balancing ecological preservation with sustainable agricultural practices is a global issue. Erhai Lake has felt this challenge keenly. To address it, in 2022, a Science and Technology Backyards(STBs) project was launched in Gusheng Village. The goal of this is to care for the environment while ensuring that farms and farmers can thrive sustainably. The uniqueness of the Erhai STB arises from its interdisciplinary integration, encompassing fields such as ecology, agronomy and social science, resulting in specifically-designed solutions for the Erhai context. While this model aligns with broader STB paradigms, its distinctive edge lies in technological innovation and robust support mechanisms for local agricultural stakeholders. This paper describes the methodology and outcomes of the STB initiative, highlighting its pivotal role in spearheading sustainable transition in Erhai. Preliminary findings underscore the potential of the STB model as an efficacious tool for harmonizing environmental conservation and agricultural practices, that are both financially and environmentally sustainable, rendering it a potential model for comparable regions in China and other counties.

Vegetable oils are a source of energy, essential fatty acids, antioxidants and fat-soluble vitamins useful for human health care and development. These oils also contribute to organoleptic quality of their products’ derivatives. However, their chemical and physical properties can be modified by the mode of their extraction, storage and distribution. These modifications might negatively affect the nutritional quality of the oils. The goals of this study were to: sample different vegetable oils for cosmetic or dietary use marketed in Cameroon, and verify purity and oxidation states of each kind of oil through determination of its acidity, iodine, peroxide, saponification, refractive indexes and the conformity of the labeling. The carotene content, the level of polar components and specific absorbance were also determined. As the result, six oils namely palm, palm kernel, coconut, black cumin, peanut and shea butter were collected. Apart from labeling, chemicals and physicals parameters analyzed were generally in accordance with the Cameroonian and Codex Alimentarius standard. This study suggests that vegetable oils sampled in the Cameroonian market may not expose consumers to lipid oxidation products generating pathological oxidative stress and inflammation. However, efforts in application of existing standard need to be done as far as labeling are concerned.
