摘要
干旱区内陆河流域因其干旱、风沙及盐碱的自然环境 ,加之盲目开垦荒地、不合理利用水资源等人为因素的影响 ,改变了原有的生态平衡 ,形成了脆弱的生态环境和特殊的景观格局。其景观呈现出以荒漠为基质 ,河流廊道为核心对称分布的水域湿地 -林 (草 )地 -荒漠的宏观局格。由于水是干旱区内陆河流域的关键因素 ,为了合理利用水资源 ,积极发挥人的作用 ,从景观生态学理论与方法的角度 ,提出了以河流廊道建设、植被景观建设、绿洲景观建设为核心的生态建设方案 。
Because of natural environment of drought、wind and sand as well as saline and alkaline soil,etc.,the original ecological balance is destroyed meanwhile,vulnerable ecological environment and unique landscape pattern are formed under blind reclamation and irrational using water resource in continental river basin in arid zone. The landscape characteristics are as follows,dominated by river corridor,the landscape is symmetrically distributed with waters and wetland-forestry and grass based on desert matrix. Water is the most important element,based on this view of point,in order to use rationally water resource and bring into play man's efforts,ecological construction plan is put torward depending on the views of landscape ecological principles and methods.The main tasks of landscape ecological construction are river corridor construction,vegetation construction and oasis construction.As a result,capacity and stability of eco-system are strengthened in continental river basin in arid zone.
