新疆玛纳斯河流域自然带的系统结构及其生态学意义

Circling-Pattern's Characteristics of Naturalization and Biology Meaning of the Manas River Valley in Xinjiang

受地形影响 ,新疆玛纳斯河流域自然带呈明显的系统结构 ,形成了山地、绿洲、荒漠流域生态系统。山地是流域的水源地 ,从水、土等方面制约绿洲的物质循环 ;荒漠是流域的生态屏障 ,从光、热等方面决定着绿洲的能量平衡。绿洲是流域水、土、光、热资源的集成地 ,是干旱区人类生产、生活的理想场所。绿洲建设已完全改变了流域生态面貌 ,使流域开发带有明显的技术倾向 ,并最终决定着流域生态建设的演变。
