| 摘 要： | 为验证数字近景图像在造林成活率监测中的使用价值,利用数码相机拍摄了造林坡面近景图像,结合遥感图像处理方法,在延安市吴旗县薛岔乡德援造林项目的作业区进行了造林监测,将数字图像处理的结果用于造林坡地幼树数量的识别,统计造林的成活率、保存率及评价造林质量。与传统的样方调查方法比较,可以大为简化外业工作,其监测结果的相对误差在3%以内。

| Abstract: | Digital close range pictures taken by a general digital camera were used to monitor seedling survival rate, combined with the application of remote sensing image processing Software in the Sino- Germany Cooperation Afforestation Project in Wuqi county. The processed digital image can be used to identify the number of seedlings on sloping field and count seedling survival rate. The compared results between image monitoring method and traditional plot monitoring method indicated that the relative inspect error was below 3 %. The study showed that image monitoring of seedling survival rate in afforestation was efficient and fleet and digital pictures was more economical and more convenient. |
