| 摘 要： | 以塔里木河下游的胡杨径向生长量为研究对象,借鉴树木年轮水文学的方法,采用单因素方差分析方法,从数理统计学的角度分析了胡杨径向生长量对生态输水的响应过程。结果表明: ①距离河道300 m范围内,生态输水前后及输水期间各年份之间,胡杨的径向生长量在0.001的水平上差异极显著,胡杨对生态输水的响应非常积极; ②距离河道300 m范围外,胡杨的径向生长量在0.05的水平上差异不显著,胡杨对生态输水的响应不积极; ③线性的生态输水只是缓解了河道附近植被的衰退,改善了局部生态环境,却无法从根本上缓解整个塔里木河下游生态环境的恶化,塔里木河下游的生态环境呈现出局部改善、整体恶化的趋势。 |

| Abstract: | The Tarim River Basin,located in Xinjiang Uygur Autonomous Region in northwest China,is the largest inland river basin in China.The ecological process here has undergone great changes due to human disturbance over the past 50 years.In order to rescue the strategic green corridor in lower reaches of the Tarim River,ecological water conveyance has been bring into effect from May 14th,2000.By using dendrohydtology for reference and taking single factor analysis of variance,the authors researched how Populus eu... |
