摘要:

本文利用蘭州大學(xué)半干旱氣候與環(huán)境觀測(cè)站（SACOL站）2006-2012年陸面過(guò)程觀測(cè)資料以及榆中站氣象資料，分析了陸面各輻射收支分量對(duì)于氣候波動(dòng)的響應(yīng)，并且研究了地表反照率年際波動(dòng)變化，討論了各陸面過(guò)程參數(shù)對(duì)于黃土高原氣候背景年際波動(dòng)的反饋。并且根據(jù)黃土高原降水類型將全年分為冬夏半年討論，以得到更為顯著的年際變化特征和相關(guān)關(guān)系。結(jié)果顯示，2006-2012年氣溫降水的趨勢(shì)與近年來(lái)黃土高原暖干化總趨勢(shì)相吻合。地表淺層土壤濕度和溫度都與氣溫、降水呈現(xiàn)很好的響應(yīng)。氣候因素的綜合影響是地表反照率變化波動(dòng)的原因。通過(guò)冬夏半年資料區(qū)分探究得到，長(zhǎng)波輻射分量與氣候要素的相關(guān)較短波輻射分量與氣候要素的相關(guān)性更強(qiáng)。但總體而言，陸面過(guò)程對(duì)于該地區(qū)氣候背景波動(dòng)的響應(yīng)機(jī)制是較為復(fù)雜的。

Abstract:

By using the land surface observations data of semi-arid climate and environmental observation stations in Lanzhou University(SACOL station) during 2006-2012 and meteorological data of Yuzhong station, the response of land surface radiation budget component to climate fluctuations was analyzed, the interannual variability of surface albedo was studied and the feedback of various parameters of land surface processes for the interannual fluctuations of Loess Plateau climatic background years was discussed. The precipitation type is used to divide the whole year into winter and summer half years in order to get more significant interannual variability and correlation. Results show that the temperature and precipitation trends in recent years match the overall total Loess Plateau warming and drying trend. Soil moisture and temperature of shallow surface show a good response to air temperature and precipitation. The combined effects of climatic factors are the reason of the change of land surface albedo. Based on the study on the winter and summer data, it was found that the correlation coefficient of long-wave radiation components and climatic factors are more relevant than correlation coefficient of short-wave radiation components and climatic factors.
