查询词典 vegetation

To investigate variation of soil bacteria community in response to the change in the above-ground vegetation, soil samples were collected at three sites, i.e. bamboo groves, mixture of bamboo and broadleaf tree and broadleaf forest. To explore variation of the soil bacterial structure, 16S-rDNA-V3-fragment-base DGGE (denaturing gradient gel electrophoresis) and clone sequence BLAST technologies were applied.

The comprehensive treatment project of Tong Ken landslide consists of whittling slope、anti-landslide pile with anchoring cable、retaining wall、building ground drainages leveling off and calking slope、vegetation protection etc. After managing, under the action of earthquake load and watery the stability coefficient of landslide is up to 1.10.Then, this text researches the structural optimization design of anti-slide pile with anchoring cable. On the condition that the width of section is invariable, the height of section is confirmed by structural optimization method. This will change traditional method to optimize the height of section so that design is simplified and cost is lower.
