The correlation was found between soil moisture and herbage coverage was significant.
该模型用于模拟发生严重荒漠化的鄂尔多斯高原植物群落的季节及年生长、叶片投影盖度、蒸发系数。
The model was developed to simulate seasonal and annual growth, foliage projective cover (FPC), and evaporative coefficient in the Ordos plateau, where serious desertification happened recently.
盖度或者覆盖度是植物群落结构的一个重要数量指标。
Coverage is an important quantitative index for plant community structure.
植被盖度由原来的42.5%增加到83.5%,将蒿属植物为建群种的群落变为沙打旺—野艾蒿—万年蓬组成的群落。
Plant cover was signifisantly changed after improved. Total cover was increased from 42.5 to 83.5%. Plant community was also changed.
