提出了采用鱼眼镜头获取林分冠层图像,应用Photoshop软件测定林分郁闭度的简易测量方法(CCPS法),用该方法测取了28个固定样地的郁闭度,以冠层分析仪所测值为基准值,对该方法进行了精度和稳定性检验与测试。结果表明:该方法精度可达97%以上,稳定系数可达92.85%,且具有低成本、易便携和设备普及性高等优势。 This paper presents a simple measurement method (CCPS method) for obtaining the canopy image using fisheye lens and measuring the canopy density by Photoshop software. The canopy density of 28 fixed plots was measured by this method. Analyzer measured value as the benchmark value of the method for the accuracy and stability testing and testing. The results show that the accuracy of the method can reach over 97% and the stability coefficient can reach 92.85%. The method has the advantages of low cost, easy portability and high equipment popularity.
