参与性农村评估在物种和景观变化研究中的应用

应用参与性农村评估研究了西双版纳自然保护区勐养片的物种和景观变化 .结果表明 ,在人类活动的影响下 ,抗干扰力弱的植物种逐渐减少和消失而耐干扰强的植物种得以发展 ,导致了地区优势植被的替代 ;狩猎特别是外地人进入保护区的狩猎是大型野生动物减少的直接原因 ;当地居民因狩猎而熟悉动物的习性和栖息地 ,成为研究野生动物的信息源 ;景观变化与经济发展密切相关 ,或因经济发展而恶化或因当地居民的参与保护而地带恢复与改善 .对应用参与性农村评估研究物种和景观变化的局限性也进行了讨论 .

Application of Participatory Rural Appraisal(PPA) method in the study of species and landscape variations.

The participatory Rural Appraisal (PRA) method was applied to study the variations of species and landscape in Mengyang Nature Reserve of Xishuangbanna, which shows that under human disturbance, the tree species with lower resistance were gradually decreased and disappeared, and replaced by the species with higher resistance, resulting in a replacement of dominated vegetation. Hunting, especially the hunting of residents from the surroundings, is the direct cause of the disappearance of big size wild animals in the reserve.The indigenous people, being familiar with the habits, characteristics and habitats of wildlife, are the better information sources for the study of wildlife. Variations in landscape are closely related to economic development. Some landscapes become worse for the economic development, while others are improved due to the participatory conservation by the indigenous people.The disadvantages of the application of PRA method in the study of species and landscape variations are also discussed.
