| 摘 要： | 盖度是衡量植物群落结构的一个重要数量指标。试验以样方尺度下草地植被盖度为研究对象,通过精度评价和实际测定,比较了数字图像法与传统方格法之间的优劣。结果表明,与传统方格法相比,数字图像法具有误差小、准确性较高和操作简便的优点,可应用于草地植被盖度的样方测量。

| Abstract: | Coverage is an important quantitive index for plant community structure,which plays a more and more important role in the regional or global researches of several fields,such as ecology,climate,hydrology,and so on.The measurement method of grassland vegetation coverage and the comparison between the digital image method and the common graticulation method were studied and discussed to choose a better method.The results showed that the digital image method put forward in this paper was a better measurement m... |
