摘要
在实地调研和资料分析的基础上,着重分析银川平原生态系统的脆弱性和基本格局,分析水资源的蕴藏条件和对生态系统的支撑作用,认为在银川平原生态系统与水资源开发的关联因素中,人类的开发活动具有主导作用,黄河引用水量是绿洲生态和社会发展的决定性因素,全球变暖、绿洲内部的盐渍化、城镇及工业污水等,对银川平原生态系统及水资源的开发均具有不利的影响,同时形成更大范围和更深层次上新的耦合关系。
By on-site inspection and data analysis, the frailty and fundamental structure of ecosystem in Yinchuan Plain was analyzed. Analysis of water resource deposit condition and effect in supporting ecosystem indicated that human activity plays a leading role in coupling relations of ecosystem and water resource development. Water diverted from Yellow River is a decisive factor in eco-oasis and social development, and global warming, salted in eco-oasis as well as industrial wastewater and sewage had an unfavorable impact on ecosystem and water resource development, which will establish a new coupling relation in larger scope and deeper administrative level.
