| 1. | Because of the particularity of intertidal flat , its topography measure is always recognized as " a hot potato " 由于潮滩的特殊性,潮滩的地形测量一直是地形测量中公认的“困难区” 。 |
| 2. | Outline the actual state of the research in the field of topography measure of intertidal flat and soil water content monitoring by remote sensing at home and abroad 其主要内容包括: 1总结国内外潮滩地形测量和国内外遥感监测土壤水分的研究现状; 2 |
| 3. | Build the correlation between soil water content and topography of intertidal flat through statistics , and simulate the topography of intertidal flat in dafeng 通过统计方法,建立出露潮滩土壤水分与实测潮滩地形的相关关系,并对大丰港堤附近潮滩地形进行了反演。 |
| 4. | Summary the models of soil water content monitoring at present , and build the model of soil water content monitoring in the exposure intertidal flat . 5 分析目前常用的土壤水分遥感监测模型及优缺点,并在此基础上建立了研究区出露潮滩土壤水分的遥感监测模型; 5 |
| 5. | 3 . analyse the correlation between soil water content and spectral reflectance of intertidal flat , and gain the best band to monitor soil water content by remote sensing . 4 对实测潮滩土壤水分与实测潮滩土壤光谱反射率进行了统计相关分析,得出了可见光及近红外波段范围内土壤水分遥感监测的最佳波段; 4 |
| 6. | Intertidal flat is a place where seawater constantly rises and falls . as a vanguard zone where sea and land interact , the features of intertidal flat are largely on behalf of the characteristics of its own coast 潮滩是海岸带中的海水涨落地段,时而出露水面,时而被海水淹没,它作为海陆交互作用的前锋地带,其特征在很大程度上代表了所在海岸的性质。 |
| 7. | Based on the research of intertidal flat topography measure at home and abroad , this article avoids some problems troublesome , such as the dependence of the station of tide gauging , precise match of images and so on . first , we monitor soil water content of intertidal flat through building correlation model between soil water content of intertidal flat and landsat tm data , then we analyse the correlation between soil water content and topography of intertidal flat , last , we extract topography of intertidal flat combining with gis 本文在总结国内外潮滩地形测量研究的基础上,避开对潮位站的依赖和影像精配准问题,以江苏大丰港堤附近淤泥质潮滩为研究区域,通过遥感方法建立潮滩土壤水分与tu光谱值的定量数学模型,提取潮滩土壤含水量信息,然后通过潮滩土壤水分与地形的定量关系,结合gis技术反演潮滩地形。 |
