中文摘要： 高效快捷的宏观资源监控体系是药用植物资源有效管理和合理决策的关键。内蒙古甘草资源调查证明了低空遥感技术高效性，针对药用植物分散性、群居性特点，本课题研究高中低分辨率互补的药用植物资源多级调查体系建立和关键问题。为提高调查结果的现势性和准确性首次将高分辨率低空遥感技术引入到药用植物资源调查体系；基于最小二乘原理研究中分辨率卫星影像适合荒漠地区地面植被估算因子，以确定植被覆盖区域；在地面植被覆盖区域内布设高分辨率调查区，利用模糊聚类理论研究高分辨率低空遥感影像中不同植被群落的界限划分，实现模糊实体的边界化和数字化以确定群落空间分布格局；根据不同群落分布特点研究基于最优理论的地面样地抽样方案以提高调查结果的科学性和准确性，有效缩短调查周期及时反映药用植物资源的现势状况。通过本研究可建立快速高效的药用植物资源调查平台和技术标准。

英文摘要： Highly effective quick macroscopic resources monitoring system is vital for the medicinal plant resources effective management and the reasonable policy-making. The Inner Mongolian wild Glycyrrhiza resources investigation has proven low altitude remote sensing technique highly effective, in view of medicinal plant dispersivity and sociality characteristic, this topic study the key question and establishment of high moderate low resolution supplementary multistage investigation system for medicinal plant resources. In order to enhance the survey result's accuracy,the high resolution low altitude remote sensing technique is introduced for the first time to medicinal plant resources investigation system; Based on Least Square Principle, researching the wilderness area groune vegestation estimate factor for moderate resolution satellite image to determine the vegetation covering the region; Covers in the region in the ground vegetation to build the high resolution investigation area, using fuzzy clustering theory to study different vegetation community's boundary division by high resolution low altitude remote sensing image to realize the fuzzy entity boundary and digitization to determine the community spatial distribution pattern;According the different community distribution characteristic,study the ground investigation sampling scheme to enhance the accuracy based the optimal theory,reducing the investigation cycle in order to reflect effectively the current situation condition of medicinal plant resources. May establish the fast highly effective medicinal plant resources platform and the technical standard through this research
