“3S”技术在林业信息化中的应用
摘要
进入21世纪以来,社会经济发展迅速,原本一些经常使用的森林资源调查方法因局限性过大已经难以满足现代林业技术发展的需要。在这种前提下,发挥3S技术的优势,将其用在现代林业信息建设中就显得十分重要。将地理信息系统技术(GIS),遥感技术(RS)、全球定位系统技术(GPS)这三种独立的却有密切关系的高、精、尖技术系统整合在一起,在实际应用的过程中互相补充、这样能够发挥出十分巨大的作用。利用"3S"这种技术系统能够快速地、廉价地获得标的物的空间位置、属性,既能够避免以往调查方法的不足;又可以在捕捉查找林火信息、探查森林资源、统计植被数据和野生动物数据、预查病虫害、进行林业专题图编制和管理经营森林资源等方面发挥其不可替代的作用。文章中,我们将对传统林业调查的弊端进行分析并详细介绍"3S"技术在现代林业中应用的先进性和优势性。
Since entering the twenty-first Century,the social and economic development has been developing rapidly. The forest resources investigation methods originally used frequently are too large to meet the needs of modern forestry technology development.On this premise,it is very important to give full play to the advantages of 3 S technology and use it in the construction of modern forestry information. The technology of geographic information system(GIS),remote sensing(RS),global positioning system(GPS)of the three independent but closely related to the high precision and advanced technology system together, in the course of the practical application,in which complementing each other can play a great role. The use of "3 S" technology,this system can quickly and inexpensively object spatial location and attributes,can avoid the shortcomings of previous survey methods; and it can play its irreplaceable role in capturing the search information, exploration of forest resources, forest fire statistics data and vegetation data,wild animal pests,precheck Forestry Thematic Map preparation and management of forest resources management. In this article,we will analyze the disadvantages of the traditional forestry survey and introduce the advanced and advantages of the application of "3 S" technology in modern forestry.
