文摘 位于我国西南、以纵向山系和大河为主体特征的纵向岭谷区,其地表主要自然物质、能量输送和人类活动等,表现出明显的"通道-阻隔"作用,产生了复杂多样的关联效应:使其成为亚洲大陆主要的纵向生物走廊、避难所和我国与东南亚重要的生态廊道,拥有北半球除沙漠和海洋外的各类生态系统,是全球生物物种的高富集区和世界级基因库,但其生态脆弱、灾害频发;主导了区内多民族沿河谷分布、在山间盆地聚居的"大分散、小聚居"格局,其社会经济发展地域分异大.因此,该区一直是地学和生物学等研究地表复杂环境系统与生命系统演变规律的关键地区,在全球具有不可替代性;同时,该区资源富集,短期开发行为多、环境退化加剧、贫困普遍,保护与发展矛盾极为突出,在西部具有典型性和代表性.
其他语种文摘 Characterized by longitudinal mountain ranges, major rivers and deep valleys, the longitudinal range-gorge region ( LRGR) in southwest China is regarded as unique worldwide in terms of landscape and biodi-versity. The distinct " corridor-barrier" phenomenon caused by energy transportation and human activities makes the region an important ecological and economic corridor that links China and the Southeast Asian countries. While it houses every ecosystem in the northern Hemisphere except desert and ocean types, and is widely acknowledged as the concentrated area for various species and global gene reserve, it is subject to ecological vulnerability and fre-quent occurrences of natural disasters. Different ethnic groups scatter in small basins embraced by big mountains and present vast differences in respect of social and economic development. As a result, LRGR has long been re-garded as a key area for earth sciences and biology research in search of environment and ecosystem change; mean-while , LRGR is also a typical area in Western China characterized by high concentration of resources, worsening of environmental deterioration, impoverished rural poor, as well as contradiction between protection and development. Located in the upstream of the four major international rivers in Asia, LRGR is the hinge for Chinas regional cooperation with southeast and south Asia. At present, the region is under multi- and large-scale disturbance, pro-jecting serious ecological problems. For example, in Chinas ongoing development programs such as West Develop-ment, the region serves as resource bases for biology, ferrous metal and hydropower (with more than 30 cascade dams) ; while in the international passage program, 3 international expressways, 3 railways and 3 navigation chan-nels will span the region. Along with the construction of such major engineering projects, ecosystem degradation and transboundary ecological security will become increasingly serious, which in turn makes LRGR a sensitive area that deserves global attention. Multi-disciplinary and cross-sector studies on transboundary resources in the region are directed to serve 3 major national needs: Qtargeting at the national West Development Strategy to identify core scientific issues of ecological development and infrastructure construction in plateau mountains; ?targeting at na-tional ecological security to develop maintenance mechanism and control methodology for transboundary ecological security and resource bases development; ?targeting at the national opening-up to south Asia to provide scientific grounds for multi-lateral diplomacy, trade and economic cooperation, as well as conflict resolution.
