Evaluation on Nondestructive Plant Strength for Typhoon and Earthquake Areas in Taiwan

Abstract

Abstract:In this study need to construct the criteria of landslide area protection for the selected vegetation materials in considering their characteristics and the soil solidities for the root system. Selection three pioneer plants, India-charcoal Trema, Formosan alder and Roxburgh sumac, doing destructive pulling resistance test. By the weight of plant above the ground, weight of root-soil, and get non-destructive resistance models. With the diameter of the tree just above the ground, were derived with multi-variable regression analysis, respectively. The models gave higher statistical regression coefficients when they were compared with the results of relative researches. The significant level factors to influence the plant pulling resistance capacity are climate and soil properties that fitting models of root strength provided the quantitative prediction on slope stability in the landslide areas.
