| 中文摘要 | 土壤侵蚀是遥感、地理信息系统应用研究的重要领域，它们为土壤侵蚀研究提供丰富的信息资料和处理手段，开辟新的广阔空间，并把水土保持工作推向更深的层次。土壤侵蚀模型是预报水土流失、指导水土保持措施配置、优化水土资源利用的有效工具，是水土保持研究的热点。在“中国科学院西部行动计划——三峡库区水土保持示范区”项目资助下，从水土保持的科学体系出发，选取晨溪河小流域为例，以遥感及GIS理论技术为基础，探讨了USLE土壤侵蚀预测模型信息系统的实现及应用。本文首先综述了土壤侵蚀模型，介绍了遥感与地理信息系统发展及其在水土保持研究中的应用，水土保持信息系统发展现状等。以USLE土壤侵蚀模型为例，对其降雨侵蚀力、土壤可蚀性因子、坡度坡长地形因子、植被覆盖因子进行了详细深入分析，并提出了合适的提取方法。本文详细介绍了ArcGIS Engine组件开发方式，并在面向对象开发平台VISUAL BASIC 6.0上进行了土壤侵蚀信息系统开发。在土壤侵蚀理论分析研究的基础上，选择在本研究区具有可行性的各土壤侵蚀因子，围绕土壤侵蚀预测模型的实现，开发并实现了晨溪河小流域土壤侵蚀预测信息系统。实现了水文分析、表面分析、坡长提取、矢量栅格转换及空间要素查询等功能，并实现了各个土壤侵蚀模型因子的自动提取与计算，最终实现了水土流失量的自动估算。本文以忠县晨溪河小流域为例，展示了预测信息系统在三峡土壤侵蚀快速调查中的应用效果。对三峡小流域具有一般适用性，其它小流域土壤侵蚀预测信息系统功能也与之类似，并可推广到其它地区。本文基于对小流域土壤侵蚀过程的分析，在前人理论研究成果的基础上，建立了小流域土壤侵蚀预测信息系统,为后期水土保持工作的开展提供了科学依据。文章探索了基于GIS和RS的水土流失预测模型开发，促进了小流域水土流失研究得到进一步的发展和完善。 |
| 英文摘要 | Soil erosion is the important application areas of remote sensing, geographic information system ,whom providing rich methods and information processing tools for soil erosion research , and openning up broad new space, and improving water and soil conservation work to a higher level. Soil erosion model is an effective tool to predict soil erosion and to guid the soil and water conservation measures to the allocation, and to optimize the use of land and water resources. It is the hot area of the soil and water conservation research.Funded by the "Plan of Action for the western Chinese Academy of Sciences - the Three Gorges reservoir area Soil and Water Conservation Demonstration Area" project, starting from the scientific system of water and soil conservation, taken ChenXi River watershed as an example, based on the theory of remote sensing and GIS technology, USLE soil erosion prediction model Information System Implementation and its application are discussed in this paper.First of all, soil erosion model is summarized and then remote sensing and geographic information systems development, researchs in the application of soil and water conservation, and development of soil and water conservation information systems are introduced. USLE soil erosion model is taken as an example to analysis Rainfall erosivity factor, soil erodibility factor, slope and slope length terrain factors, vegetation cover factor in-depth, and put forward suitable extraction methods.The development methods of the ArcGIS Engine components is described in this paper, and soil erosion information systems is developed on the object-oriented development platform VISUAL BASIC 6.0. On the basis of soil erosion theoretical analysis, the various soil erosion factors of viability are choosed in the study area and on the purpose of realizing soil erosion prediction model , the ChenXi river watershed soil erosion prediction information system is developed and realized. hydrological analysis, surface analysis, slope length extraction, conversion between Vector and raster and enquiry of space elements are realized, and other functions, such as automatic extraction of the various factors of soil erosion model with is achieved and the ultimatly the automatic estimation of soil erosion is realized .Taking ChenXi small River Valley in Zhongxian County as an example, the application effect of the prediction information system in the Three Gorges rapid soil erosion investigation is displayed. It also can be applicability on the other small watershed in Valley of the Three Gorges.The soil erosion prediction information systems with similar functions, and it can be extended to other areas.Based on the analysis of process of soil erosion in small watershed and the outcome of the previous theoretical study, the establishment of the small watershed soil erosion prediction information systems providss a scientific basis for the latter development of soil and water conservation. Development of soil erosion prediction model based on GIS and RS is explored and development and improvement of small watershed soil erosion study is promoted further in this paper. |
