新疆树木年轮研究特色

本对40多年来新疆树木年轮研究工作做了简要总结．发现有以下研究特色：1．在年轮水学方面开启了我国利用树木年轮重建河流径流量和河流径流深度场研究的先河；2．在年轮气候学方面，主要是利用树木年轮重建空间上大尺度的气候要素变化，开创我国沙漠地区树木年轮研究工作，利用树木年轮重建某地区单旬降水和山区降水日数，研究了雪与树木年轮的关系以及冰期与降水的关系，创立大样本、多年表、面控制的采轮布局策略等；3．在年轮与环境方面利用树木年轮做春小麦气候产量预报，建立了树木年轮与大气环流因子的关系等。

Features of the Studies on Tree Rings in Xinjiang

The paper reviews the 40-year studies on tree-rings in Xinjiang,and concludes there are several characteristics as following.the first research on reconstruction of the flow-off and the depth field of flow in dendrohydtology; 2 The major characteristics in dendroclimatology are climate reconstruction in the large scale space and initiating the study on tree-ring n desert,reconstruction the precipitation in period of ten days and the precipitation day numbers in the mountain region,and researching the relationship between snow and tree-ring and between ice age and precipitation,and originating the method with a large number specimens and chronolgices,also the layout tactics during the process of gathering and so on; 3 In tree-ring and environment,the forecasl of the climatic output of spring wheat by use of tree-ring chronologies and establishment of the correlation of tree ring with factors of general circulation.
