应用遥感技术进行森林资源监测方法的研究

The Study of Methodology of Forest Resources Monitoring on the Base of Remote Sensing Techniques

森林资源有较强的动态性,监测技术的改进具有重要的生产意义。采用遥感技术,地理信息系统技术与森林连续清查技术相结合的方法实施森林资源监测具有极大的潜力。通过在松江河进行的研究,证明了这种方法的可行性和优越性。 文章探讨了使用新方法的关键技术环节,提供了实施监测的实际结果,指出了在我国北方国有林区推广的前景。与传统方法相比,新方法提供了图面资料,减少地面工作量50％,降低经费20％。

Forest resources possess strong dynamic chracteristics. The improvement of the techniques used in monitoring forest resource changes will be of important significance in forest production. The method for combining remote sensing technique, GIS technique and forest continuous inventory technique has great potentiality in forest resource monitoring. The study conducted in Songjianghe Forest Bureau has proven the feasibility and superiority of the method.This paper has explored the key technical links in applying the new method, provided the practical results of monitoring and exhibited the prospects for promoting the method in state-owned forest areas. Compared with the traditional methods, the new one will produce map data and reduce the ground workload by 50% and the cost by 20%.
