摘  要：
针对典型草原土壤结构特征及草原风蚀退化的现状,在内蒙古自治区锡林郭勒盟乌珠穆沁典型草原地区,选取约400km2面积的研究区,采用"3S"一体化技术,获取典型草原地表特征及采样点的三维坐标数据,通过实地打点取样,测量栗钙土层厚度,并结合SuperMap软件建立栗钙土层结构DEM模型。经分析研究可知:栗钙土层结构受多种因素影响,不同地形结构可能有不同的土层厚度。建立土壤结构模型,研究环境条件与土壤结构关系,推断土壤的空间分布,可以实现草原土壤结构动态监测,为预防和控制风蚀沙化提供基础数据,为典型草原生态保护与合理利用提供了科学依据。

摘  要：
Aiming at the soil structural characteristics and wind erosion degradation situation of the typical grassland,it is about 400 km2 areas of Wuzhumuqin typical grassland in Inner Mongolia Xilinguole City that was selected as the research object.By means of the "3S" integration technologies,the surface characteristics of the typical grassland and three-dimensional coordinate data of the sampling points were obtained in this paper.The Chestnut Soil Tier structure DEM model was established through measuring the chestnut soil thickness in terms of choosing dot and sampling,and using the SuperMap software.As is shown from the research results,the Chestnut Soil Tier structure was affected by many factors and the different terrain structure may have different soil tier thickness.By establishing the soil structure model,studying the relations between the environmental condition and the soil structure,and further deducing the soil space distribution,we can realize the dynamic monitoring for the grassland soil structure and provide the scientific data for the wind-erosion-and-desertification prevention and control as well as the scientific foundations for the ecological protection and rational utilization of the typical grassland.
