| 摘 要： | 在参考历史文献和考古成果的基础上,结合野外考察,研究了历史时期以来塔里木河下游的环境变迁和人类活动演化过程.研究认为,历史时期下游地区人类活动受气候影响下的河流生态环境变化的制约;19世纪末以来塔里木河上游地区的水土资源开发,使得下游水量减少,造成下游生态环境急剧退化,下游人类活动虽不稳定,但总体是进步的.20世纪90年代以来,下游生态环境进一步恶化,在制度与技术进步的支持下,人类生产空间扩张迅速、效益不断提高的同时,下游河道进一步退缩,天然绿洲沙漠化持续发展,下游尾闾垦区毗连沙漠,成为抵御绿洲生态环境退化的生态经济区,人工绿洲维持发展的代价高昂.因此,下游人地关系走向良性发展的前提是全流域开发利用水资源保持在下游生态环境不退化的限度内.
