中国三江源区基本生态特征与自然保护区设计

文中引入生物区域规划与管理的新思路,将三江源区作为一个完整的生物地理区域,建立生物区域自然保护区网络。并简要介绍了利用景观生态学、种群生存力分析等理论和景观规划途径、GIS分析等先进方法从区域层次确立自然保护区网络,在网络的每个节点(保护区)研究核心区面积、形状,以及网络与节点的连接(廊道)的程序、技术和方法。

Basic Ecological Characteristics of the Three-Rivers' Source Area and Design of the Nature Reserve

The Three Rivers' source area refers to the source catchment of the Yangtze River, the Yellow River and the Lancang River It is located in the hinterland of Qinghai Tibet Plateau and forms a unique ecosystem in the world. It has been described as the "Water Tower of China" A large salvage nature reserve in the Three Rivers Source area is very important and urgent, which will safeguard the ecological security of three rivers' drainage area and boost the sustainable development of the three rivers' source area The paper puts forward a new way to build the nature reserve networkIn this paper, the source area has been viewed as an integrative bio geography area. And it concludes that a biota nature reserve network can be built in the source area through planning and management of biota The paper recommends the theories of landscape ecology be used and the population viability analysis be conducted Then the paper establishes the source nature reserves net from the area coverage by using the landscape planning and GIS analysis, analyses the area and the shape of the core zone of every net node and the process and technology of cennecting the corridors with nodes
