Abstract:

Quantifying researching on 3-dimension green quantity and ecological benefit of plants on main districts river bank in Liuzhou, may provide some scientific basis and reference for landscape ecological environment construction of urban bank green land and the theoretical foundation for the realization of ‘nature-human-water’ sustainable development. Basing on the measurement of each tree, used green quantity equation to calculate the 3-dimension green quantity of plants, through the 3-dimension green quantity of plants, we could convert the ecological benefit. And the results were as follows: the evergreen tree provided the biggest green quantity, which accounted for 78.76% of the total; the evergreen tree provided the biggest ecological benefit, in the respect of releasing oxygen quantity and absorbing carbon dioxide quantity, the evergreen tree accounted for 86.68% of the total, in the respect of absorption sulphur dioxide quantity, transpiration quantity and laying dust quantity, the evergreen tree accounted for 78.77% of the total, but the bush and the herb were very small. The main influence factors of 3-dimension green quantity and ecological benefit of plants were plant diversity, plant disposition, maintenance and management.
