| Abstract: | Quantity and bio-community structure, the ecological function and the utilization feature of the terrace slope ecosystem were investigated and analyzed in the paper. In the hilly areas of Sichuan basin, the terrace slope resource area is considerable and amounts to 512,320ha, the bio-community structure of the terrace slope ecosystem is diverse. Rational constructing the terrace slope ecosystem could strengthen the terrace slope, improve the soil quality and control the soil erosion. The sustained utilizing prospect of the terrace slope resource could make varied the produce and increase the biodiversity of agro-ecosystem and agricultural income. |
