Abstract: | Based on the theory of ecology, this article conducted a landscape ecological evaluation on Leucaena leucocephala artificial forest in the arid-hot valley, Yuanmou Xiaokua hill, using a combination method of qualitative analysis and landscape
comprehensive evaluation. The comprehensive evaluation indexes of landscape include forest coverage, biodiversity, stability,
soil erosion, environmental quality, availability, scientific research characteristic, economic benefits. Using AHP (analytical
hierarchy process), determine the grade of ecological evaluation factors and the weight of evaluation index and calculate
the CEI (comprehensive evaluation index) on ecological evaluation. Evaluation results showed that the area CEI was 0.714 225,
a better quality of the ecological level, but biodiversity indicators was the lowest. To sum up, it was difficult to maintain
ecological restoration effectiveness and process but also guarantee a good biodiversity in the arid-hot valleys. We must reasonably
arrange the alien species and the native species, in order to obtain a stable and sustainable eco-system.
