中文摘要	在树木年轮学与气候学理论基础上,以新疆和田地区玉龙喀什河与策勒河下游河岸胡杨为研究对象,基于流域对应的气象、沙尘天气日数、策勒河径流量等因子,分析了玉龙喀什河与策勒河流域胡杨年轮对气象因子的响应特征,以明确干旱荒漠区胡杨生长过程中的气候限制因子,为促进胡杨生态修复及沙尘防治提供理论依据。结果显示:(1)1976-2018年期间,两流域的气象条件基本一致,其中年均气温呈明显上升趋势,年均降水量呈波动上升趋势,大气相对湿度呈下降趋势,年均沙尘暴、扬沙、浮尘日数均呈显著下降趋势;玉龙喀什河流域的胡杨年轮指数呈先显著上升后整体平缓变化的趋势,而策勒河流域的胡杨年轮指数从1985年开始呈较显著的上升趋势。(2)策勒河流域胡杨年轮指数对年均气象要素的响应显著高于玉龙喀什河流域,且策勒河流域树木年轮指数与年均气温呈显著正相关关系(P<0.01),但两流域胡杨年轮指数对年均降水量和大气相对湿度的响应均不显著。(3)玉龙喀什河流域胡杨年轮指数与2月份的大气相对湿度呈显著负相关关系(P<0.05);策勒河流域胡杨年轮指数与3、 4、9、10月份的气温呈显著正相关关系,与6月份的大气相对湿度呈显著负相关关系(P<0.05),与2、4月份的径流量呈显著负相关关系。(4)玉龙喀什河流域胡杨年轮指数与秋冬季节的沙尘暴日数、扬沙日数均呈显著负相关关系;除1、2月份外,策勒河流域胡杨年轮指数与月沙尘(沙尘暴、扬沙、浮尘)天气日数基本均呈显著负相关关系。研究认为,玉龙喀什河与策勒河流域的降水稀少且蒸发量大,胡杨生长所需水源主要依赖于地下水和地表径流的补给,策勒河流域胡杨年轮指数受气温、径流量以及修建水库的影响比较明显。
英文摘要	Based on the theory of tree ring and climatology,Populus euphratica along the lower reaches of Yurungkash River and Cele River in Hotan area of Xinjiang was taken as the research object.Based on the corresponding meteorological factors in the watershed,dust weather days,the runoff of Cele River,the response characteristics of P.euphraticain two basins to meteorological factors were analyzed to determine the characteristics of P.euphraticain the growth process of the arid desert area.The climate limiting factors provide theoretical basis for promoting the ecological restoration of P.euphratica and sanddustweather prevention.The results showed that:(1)during 1976-2018,the meteorological conditions of these two river basins were basically the same.The average annual temperature showed an obvious upward trend,the average annual precipitation showed a fluctuating upward trend,the relative humidity of the atmosphere showed a downward trend,the average annual sandstorm,blowing sand,and floating dust days all show a significant downward trend;the P.euphratica annual ring index in the Yurungkash River Basin showed a significant increase first and then the overall trend of gentle changes,while the P.euphratica annual ring index in the Cele River Basin has shown a significant upward trend since 1985.(2)The response of tree ring index of P.euphraticain the Cele River Basin to annual meteorological factors was significantly higher than that in the Yurungkash River Basin,and tree ring index of the Cele River Basin had a significant positive correlation with annual temperature(P<0.01).However,the ring index of P. euphratica has no significant effect on annual precipitation and relative index of atmosphere.(3)There was a significant negative correlation between ring index of P.euphratica and relative humidity in February in the Yurungkash River Basin(P<0.05);there was a significant positive correlation between ring index of P.euphratica and temperature in March,April,September and October in the Cele River Basin, and there was a significant negative correlation between ring index of P.euphratica and relative humidity in June(P<0.05),and there was a significant negative correlation between ring index of P.euphratica and runoff in February and April.(4)The annual ring index of P.euphraticain the Yurungkash River Basin has a significant negative correlation with the days of dust storms and blowing sand in autumn and winter;except January and February,and the annual ring index of P.euphraticain the Cele River Basin has a significant negative correlation with monthly sand dust weather days.The study showed that two basins have sparse precipitation and large evaporation.The water source for the growth of P.euphratica mainly depends on the supply of groundwater and surface runoff.The annual ring index of P.euphratica in the Cele River Basin is obviously affected by temperature,runoff and reservoir construction.
