摘要：举例说明遥感与林业信息需求的关系。分析了不同目的的信息需求类型 ,以及遥感所能满足的实际应用的可能性。对最近的林业遥感应用进行了回顾和总结。引述实例来说明基于用户和市场需求的新的地球观测技术应是什麽样的。结果表明 ,遥感技术的开发需要考虑能否解决信息需求问题、如何评价遥感数据生产和分发基础的问题、如何平衡从遥感数据获取林业资源信息的费用和效益问题等。
The paper is to illustrate the relationship between the information needs and the use of remote sensing in forestry. Recent forest information needs are summarized. The analysis is focused on the possibility of operational remote sensing applications in providing the information needed. A project entitled 'SAR for Agriculture and Forestry in Europe'(SAFE) is used as an example of development of new earth observation tools based on user and market requirements. The results indicated that the development of remote sensing methodologies requires the meeting information needs, evaluation of production infrastructure and delivery of remotely sensed data, and balancing the costs and benefits of forest information retrieving. Finnaly,the limitations for the forestry remote sensing application in China have discussed,which include; 1)relatively low space resolution of satellite date;2)relatively expensive relatively expensive recent remote sensing data,like TM and Spot;3)Copyright limitations on satellite data sharing;4)difficulty of obtaining optical data due to cloudy.Anyway and remote sensing is a kind of technique,which is essential for inproving forest management.However,it must be point out that remote sensing alone cannot provide all the information needed and remote sensing can not replace some of traditional ground inventory mdehods.
