The oxygen isotope in tree ring,as a proxy of paleoclimatology with high resolution, is develop late but fast in Asia. Stable oxygen isotope ratio(delta~(18)O) of tree ring records strong environment information,and related to moisture cycle closely,which makes it important in studying complex Asian climate. Tree ring delta~(18)O responses to temperature mainly in high latitude region,for middle to low latitude,it records moisture change like precipitation,relative humidity(RH) and PDSI. This study statistics the published correlation analysis results of tree ring delta~(18)O with temperature,precipitation and RH in Asia,it appears that the environment of growing season is crucial to tree ring delta~(18)O,the significant relationship of tree ring delta~(18)O with temperature,precipitation and RH is positive,negative and negative respectively. Temperature and precipitation influence rainfall delta~(18)O thus tree ring delta~(18)O,but their effects varies at difference region; RH is widely recorded in the tree ring delta~(18)O. As the majority of study regions located in middle to low latitude region,most tree ring delta~(18)O series are used to study Asian summer monsoon and ENSO through its relationship with monsoon rainfall; Seasonal resolved tree ring delta~(18)O studies only carry out in tropical and subtropics area now,but they are meaningful to understand intraannual climate change and monsoon activity,and make it possible to study species without distinct annual rings.
