中文摘要	原全球土壤质地类型分布在黑河地区的数据(下称原全球数据)不能体现该流域不同海拔高度土壤分布的非均匀性特征,为了定量表征研究区土壤的非均匀分布,在流域范围收集了53个土壤亚类剖面数据,对照土壤三角,与国际通用的STASGO 30 s土壤质地类型分类标准对应,基于黑河流域1∶100000土壤亚类分布图,建立了黑河流域30 s分辨率的土壤质地类型分布图(黑河数据).这套数据可以描述出原全球STASGO 30 s数据不能表现出的山区和绿洲区的土壤非均匀分布实际.分别使用黑河数据和原全球数据作为下垫面土壤分布,运用耦合了陆面过程的中尺度大气模式,对黑河流域中上游区域进行了模拟,检验了两套数据对气温模拟的准确性,讨论了土壤分布变化对环境要素模拟的影响.结果表明,使用黑河土壤分布数据对上游山区的气温模拟性能好于原全球数据,中游绿洲区使用两套土壤分布数据的模拟值都偏高,大部分站点使用黑河土壤分布数据的模拟值略高于使用原全球数据的模拟值.这可能与模式中使用的全球土壤水、热参数在研究区的代表性以及中游区的人类活动加剧了土壤温、湿度的时空异质性有关.因此,黑河流域土壤水、热参数以及高分辨率的土壤温、湿度分布是提高该区域土壤-大气相互作用数值模拟性能的重要途径.环境要素变化与土壤类型分布变化呈非线性关系.气温模拟值对土壤分布变化最为敏感.
英文摘要	The soil texture type in Heihe River basin original Global data on Global soil texture type map could not figure out the soil heterogeneous distribution at different altitudes above sea level in the Heihe river basin.In order to reflect the uneven characteristic,particle percentage of 53 soil sample data were collected in the Heihe river basin.According to the soil triangle,each genetic type was ascribed to the soil texture type of the STASGO classification system.Based on 1∶100000 soil map in the Heihe River basin of genetic classification system,soil texture map of the Heihe River basin(Heihe data) was setup as the same standard of origihal global 30 s soil texture classification.The Heihe soil texture data describers soil heterogeneous in the mountainous region and the oasis more exactly than the global data in the Heihe river basin.The mesoscale atmospheric model MM5 coupled with the land model was used and the Heihe soil texture data and STASGO global soil texture map was used as the overlay soil distribution,separately.Effects of the Heihe soil texture data on atmospheric elements simulation were studied and compared with the simulation results by the global soil map.Influence of soil map change on the environmental simulation was studied also.The following conclusions were obtained.In upper reaches of the Heihe river basin,2 m air temperature simulations using the Heihe data are closer to the observations than the global data at 19 meteorological stations.It shows warm bias in the middle reaches. Simulation bias using the Heihe data is more than the global data mostly.It is related to the uncertainty of the local heat and hydraulic parameters and the increased heterogeneous because of the human activities.So,it become the main approaches to raise the land-atmosphere simulation accuracy by the accurate land characteristic parameters and high-resolution soil temperature/moisture distributions providing.Changes of the environmental fields distribution lead by the soil map change show the non-linear relations with the soil texture types map change.2 m air temperature simulation is more sensitive with the soil type change than the other elements.
