中文摘要： 风力发电场对所在区域的近地面大气环流有一定影响，受风力发电机叶片旋转的影响，原有地-气系统的空气流动方向及强度会发生变化，进而影响到下垫面土壤性质的变化，最终导致局部生态环境的改变。目前将下垫面土壤性质变化与风力发电场布设联系起来作为一个整体系统进行研究的尚不多见，这种集成研究对于更好的认识风能资源开发应用对下垫面土壤环境的影响有重要现实意义。本研究通过对中国北方草原区希拉穆仁草原风力发电场下垫面土壤性质与未设风力发电场下垫面土壤性质之间的时空变化进行对比研究，具体有野外定点监测并取样和室内实验分析(包括土壤的机械组成、土壤含水量、PH值、氮、磷、钾、速效养分、有机质、孔隙度、容重和地表植被生长状况等)，运用地统计软件消除监测样和参照样之间的原始空间异质后，比较风电场下垫面土样成分与参照样之间的差异，旨在探明风力发电场对下垫面土壤性质的影响效应及机理。

英文摘要： The wind feild has a certain influence for the near-surface atmospheric circulation in the region. Affected by the rotation of wind turbine blades, the air flow direction and strength of the original places - gas system will change, thereby affecting the changes soil properties in the underlying surface, eventually leading to changes in local ecological environment. Current underlying surface soil properties change with the wind farm layout to link the research is still rare as a whole system. This integrated application research could better understanding of wind energy resource development, and it also has important practical significance for the underlying surface of soil environment. In this study, through the comparative study of the underlying surface soil properties of seasonal variation between setting wind farm in the northern steppe of Xilamuren grassland and not set up wind farms, which specific has field sentinel monitoring, sampling and indoor experimental analysis (including soil composition, soil moisture content, PH value, nitrogen, phosphorus, potassium, available nutrients, organic matter, porosity, bulk density and vegetation growth status, etc.). we compare difference of the underlying surface soil properties between underlying surface of wind farms and the reference of soil samples, to study
