"3S"技术及其应用课程简介 （编号：Gpd7054004） 中文简介： "3S"技术及应用课程是为林学一级学科专业硕士研究生开设的专业基础课，其内容包括是遥感（Remote Sensing，RS）技术、地理信息系统（Geograhpyic Information system,GIS）、全球定位系统（Global Positioning System,GPS）原理及其在林业中的应用。开设的目的是为森林资源调查、监测和管理培养"3S"技术应用研究高级人才，为我国林业建设实现"数字林业"、"智慧林业"做出应有的贡献。 该课程有以下特点：(1)是一门典型的交叉性学科：该课程是一门为林学类研究生开设的综合性较强的课程，知识点多，多学科集成（地理学、地图学、测绘学、遥感科学、计算机科学、数据库、信息科学、林业专业知识等）、渗透性较强、空间抽象性强、研究对象的空间尺度变化大，应用范围广等特点。(2)是一门实践性很强的学科：该课程理论部分对林学类研究而言，内容繁多，全部消化和掌握有一定难度，只有通过实践才能更好地理解基本原理和基本概念。因此，研究生必须掌握RS图像处理的基本方法、RS图像解译方法以林业科研、生产部门使用GIS软件平台的操作方法。(3)是一门迅速发展中的学科："3S"技术的发展与计算机科学、信息技术的发展是分不开的，因此，研究生应加强相关的文献资料的查阅和学习，掌握"3S"技术的发展趋势和动态，努力更新自己的"3S"技术知识，不断提高自己的"3S"技术应用能力。 英文简介： The "3S" technology and application course is a professional foundation course for graduate students in the first level discipline of forestry. Its content includes remote sensing (RS) technology, geographic information system (GIS), principles of global positioning system (GPS), and their applications in forestry. The purpose of the program is to cultivate senior talents in the application and research of "3S" technology for forest resource investigation, monitoring, and management, and to make due contributions to the realization of "digital forestry" and "smart forestry" in China's forestry construction. This course has the following characteristics: (1) It is a typical interdisciplinary subject: it is a comprehensive course designed for graduate students majoring in forestry, with multiple knowledge points, multi-disciplinary integration (geography, cartography, surveying and mapping, remote sensing science, computer science, data banks, information science, forestry professional knowledge, etc.), strong permeability, strong spatial abstraction, and large spatial scale changes of research objects, Wide application range and other characteristics. (2) It is a highly practical discipline: the theoretical part of this course is related to forestry research, with a wide range of content, and it is difficult to digest and master all of it. Only through practice can one better understand the basic principles and concepts. Therefore, graduate students must master the basic methods of RS image processing, RS image interpretation methods, and the operation methods of forestry research and production departments using GIS software platforms. (3) It is a rapidly developing discipline: the development of "3S" technology is inseparable from the development of computer science and information technology. Therefore, graduate students should strengthen the search and study of relevant literature, master the development trends and dynamics of "3S" technology, strive to update their "3S" technology knowledge, and continuously improve their "3S" technology application ability.
