摘要

利用2015年6月1日至7月24日干旱区地膜覆盖玉米农田下垫面的观测资料,分析地表反照率在植被生长期间的变化特征及其与土壤湿度的关系。与未覆盖地膜情形的下垫面相比,地膜覆盖农田下垫面地表反照率的变化特征及其与土壤湿度的相关性具有显著性差异。为此建立了相应的地表反照率动态参数化方案,并将修改的地表反照率动态参数化方案应用到陆面过程模式CoLM中进行了3组模拟试验,分析和检验新方案在地膜覆盖农田下垫面的准确性和适用性。数值模拟结果表明:3组试验都能很好地反映陆面过程特征的日变化趋势,但是相比较而言,利用新建立的地表反照率动态参数化方案模式的模拟效果最好,明显提高了模式对向上短波和长波辐射的模拟能力,使浅层土壤温度和湿度的模拟效果有了一定的改善。因此,地表反照率动态参数化方法对干旱区地膜覆盖农田下垫面陆面过程的模拟效果有一定的改进,对今后陆面过程模式的发展和完善有较好的参考价值。

Abstract

Based on the observed data of surface albedo in maize cropland mulched by plastic film in an arid region from June 1 to July 24,2015,the variation of surface albedo during the vegetation growth period and the relationship between surface albedo and soil moisture content were analyzed. It was found that the surface albedo variation and the correlation between surface albedo and soil moisture content were significantly different from that on underlying surface without mulching plastic film,thus a corresponding dynamic parameterization scheme of surface albedo was established.Furthermore,the modified dynamic parameterization scheme of surface albedo was applied to the land surface process model CoLM,and three simulation tests were carried out to analyze and verify the accuracy and applicability of the new scheme on cropland underlying surface mulched by plastic film.The numerical simulation results showed that the three tests could reflect the daily variation trend of land surface process,but the comparison revealed that the simulation performance of the new model was the best,because the simulation capability of the upward shortwave and longwave radiation was obviously increased,and the simulated results of soil temperature and soil moisture content in shallow soil were improved to some extent.Hence,the dynamic parameterization method of surface albedo could significantly facilitate the land surface process simulation capability on cropland underlying surface mulched by plastic film in arid region,and it could be referred in further developing and improving the land surface process models in the future.

Key words： plastic film mulching; maize cropland; surface albedo; dynamic parameterization method; numerical simulation; arid region
