摘要
森林资源调查是国家森林资源监测体系的重要组成部分,是极其重要的林业基础工作。本文结合洛川县森林资源规划调查工作实践,根据SPOT5高分辨率卫星影像特点,从屏幕目视判读区划工作流程和方法等方面探讨SPOT5信息提取,对调查成果做了分析。结果表明:采用SPOT5高分辨率卫星影像屏幕目视判读区划方法组织森林资源规划调查,是切实可行的,能够大幅度提高调查工作效率、保证了调查成果的精度和可靠性。
Forest inventory is an important part of national forest resources monitoring system and is extremely important basic work in forestry in China.Based on the investigation of Luo＇chuan forest resources planning and the characteristics of SPOT5 image data,this paper discusses the division of land type process and methods from screen visual interpretation as well as the SPOT5 information extract.The results showed that screen visual interpretation division by SPOT5 image data of high-resolution for the organization of forest resource planning is feasible and can greatly improve the efficiency of the forest inventory and ensure the accuracy and reliability of survey data.
