Study on the diversity pattern of natural herb under the forest of Shanghai Green Belt during its early building-up period
An investigation of the natural herb under forest of Shanghai Green Belt was made, where 277 community plots were surveyed. The results show that the flora of the natural herb recorded in the study area includes 88 species, 73 genera and 33 families, which were divided into 49 community types, with the annual plant as their dominant species. This suggested that there was a high diversity of community types under the forest of Shanghai Green Belt during its early building-up period owing to the condition of good sunlight. Moreover, it was better for the highly adaptable annual plants to grow there because of the high frequency of human disturbances.
