森林覆被下铜仁地区环境遥感研究动向

Research Trend of Environmental Remote Sensing Under Forest Cover in Tongren Prefecture

指出了森林生态系统参数在突出区域生态特色、诊断当前生态系统健康、分析生态系统时空演变等研究中具有重要的作用,遥感技术在提取相关森林生态参数时具有大尺度、省时、高效、准确等优势,是主要的信息采集途径。总结了林业遥感的技术应用范畴,分析了阻碍林业遥感迅速发展的主客观原因,提出了在大生态背景下,依据区域森林资源特色、特殊地表带环境特点来分析铜仁市级区域林业遥感技术研究动向,认为可在特定林木信息提取、动态监测、环境要素反演、大数据分析方面展开深入研究,以期为区域生态环境保护、区域生态旅游资源吸引力提高提供科学依据。

Forest ecosystem parameters play an-important role in highlighting regional ecological characteristics, diagnosing current ecosystem health and analyzing temporal and spatial evolution of ecosystems. The remote sensing technology as the main way of the information collection has the advantages in extracting relevant forest ecological pa- rameters with large scale, time saving, high efficiency and accuracy. This paper summarized the application category of forestry remote sensing technology, analysis of the subjective and objective reasons that hinder the rapid develop- ment of forestry remote sensing. Then, it put forward that further study is also needed under the background of the ecological environment, according to the characteristics of regional forest resources, special surface features, analysis the trends research of Tongren Prefecture regional forestry remote sensing technology. The results can provide scientific basis for the regional ecological environment protection and the attraction of the regional eco-tourism resources, providing basic data and decision basis for maintenance, measurement and control of regional ecosystem security and stability.
