选择既适应西藏独特地理环境和自然条件,减少工作量,降低成本,又能保证森林资源调查质量和满足精度要求的调查方法,是搞好西藏森林资源规划设计调查的保证。本文从这一观点出发,结合波密县调查实践,就航天、航空遥感与地面目测和实测相结合,按小班提供各类面积、蓄积量,以系统抽样控制总体蓄积量及精度方面做了有益的探讨。
To choose a survey method that meets the unique geographical environment and natural conditions of Tibet, reduce workload and reduce costs, and ensure the quality of forest resources investigation and meet the requirements of accuracy is a guarantee for improving the investigation and design of forest resources in Tibet. Based on this point of view, combining with the investigation and practice of Bomi County, this paper combines the remote sensing of aerospace and aviation with the visual observation of the ground and the actual measurement to provide various kinds of area and accumulation volume in small classes and to control the overall accumulation amount and accuracy by systematic sampling Discussion.
