本文利用国土卫星影像就京津唐地区的自然资源与环境调查进行了多学科综合应用和高层次专题制图的研究。在研究中,对影像的基本特性、质量和使用的技术指标作了较系统的分析,并按其精度、使用程度和效果等提出了评价。同时对国土卫星像片的几何配准,运用多项式与有限元法相结合的原理,进行了计算机和光学处理的对比研究。 本区资源与环境的遥感调查应用,主要是运用遥感地学原理,分析水文下垫面要素,划分水文环境类型,计算其产水量;分析非农业用地与总土地及其它用地的比例关系,探索土地利用类型结构的地域差异规律;农业低产地环境及其数量、质量特征的研究;综合调查森林资源,包括宜林地的生态环境、立地条件及宜林树种的生态与经济特性;以及以北京为中心的京津唐旅游圈及功能分区,矿产资源的赋存机制,区域地壳稳定性及区内近一万年来的自然环境的演化规律及其与国土整治、规划和城镇建设的关系等进行了多元综合研究。同时编制了一套高层次专题图件,并量算了各种资源数据。
In this paper, a multidisciplinary integrated application and high-level thematic mapping of natural resources and environment in Beijing, Tianjin and Tangshan were conducted using satellite imagery of national territory. In the study, the basic characteristics of the image, the quality and the use of technical indicators made a more systematic analysis, and according to its accuracy, degree of use and effectiveness of the proposed evaluation. At the same time, the geometrical registration of the national satellite imagery is used, and the principle of combining polynomial and finite element method is used to compare the computer and optical processing. The remote sensing survey and application of resources and environment in this area mainly uses the principle of remote sensing and geology, analyzes the underlying elements of hydrology, divides the types of hydrological environment and calculates the water yield; analyzes the proportion relationship between non-agricultural land and total land and other land, The use of the type structure of the regional differences in law; agricultural low-yielding environment and its quantity, quality characteristics of the study; comprehensive survey of forest resources, including the ecological environment of Yilin, site conditions and the ecological and economic characteristics of Yilin species; and to Beijing as the center The Beijing-Tianjin-Tangshan tourism circle and functional zoning, the mechanism of mineral resources, regional crustal stability and the evolution of the natural environment within the past 10,000 years and its relationship with land consolidation, planning and urban construction, etc. Comprehensive Study. At the same time, a set of high-level thematic maps were compiled and various resource data were calculated.
