Fengshui forest management by the Buyi ethnic minority in China

Fengshui forests, very popular among the ethnic minorities in the rural areas in Guizhou Province of China, have spiritual symbolic meanings and are strictly managed. This paper examines the nature, history, local perceptions and management of fengshui forests in two Buyi villages in the Guizhou Province. With their long history, the fengshui forests are perceived to provide good wishes, security, unity, fortune, wealth and health to the local communities. Fengshui forests act as a form of “community based nature reserve” which maintains the health of natural forests, especially hydrological features and prevention of soil erosion. Cunguimingyue (Folk Regulation and Customs) is the primary local normative mechanism that maintains the fengshui forests in a good condition. The lessons learnt from local fengshui forest management needs to be incorporated in for contemporary China's forest policy formulation as these forests play an important role in rural livelihoods.

茶多酚、茶多糖对兔动脉血压的影响

兔静脉注10mg／mL的茶多酚和茶多糖溶液，观察对动脉血压的影响，结果表明：注射荼多酚1—3mL后收缩压6次降低（9％-20％），2次升高（13％和20％），3次无变化；舒张压2次升高（20％和140％），9次无变化；注射茶多糖1-4mL后收缩压9次降低（2％-29％），3次升高（13％-40％），5次无变化；舒张压4次降低（10％-200％），7次升高（20％-50％），6次无变化。上述浓度和剂量的茶多酚、茶多糖对兔动脉血压均无显著影响（P〉0．05—0．5）。

Application of traditional knowledge in forest management: Ethnobotanical indicators of sustainable forest use

Forest management has been usefully defined in terms of production, utilization and distribution of products, and the institutional or organizational arrangements by which they are carried out. Both technical and social aspects of forest management are treated as parts of a single system. Traditional knowledge of the use and management of forests still has a vital role to play in forest management today. This is because traditional practices are believed to be often favourable towards conservation and sustainable use. It is therefore valuable to establish a framework to evaluate the contribution of traditional knowledge to forest management today. Accordingly, a framework, based on ethnobotanical information, is proposed in this paper, with quantitative and qualitative indicators suggested for different variables relating to traditional knowledge. The discussion is based on ethnobotanical case studies from Yunnan and other provinces of China in which we have been working.
