This chapter examines about landscape indices and statistical method such as logit model to assess the effects of human developments on the Shihmen reservoir catchment from both temporal and spatial perspectives, and to further investigate the major environmental drivers for landscape changes. The developing field of landscape ecology has provided a strong conceptual and theoretical basis for understanding landscape structure, function, and change. From a landscape ecology perspective, changes in a human-dominated landscape are often due to human factors such as road development, crop cultivations, and urban expansion. Human activities would affect the landscape composition, structure, and function by changing natural land-forms. Growing evidence that habitat fragmentation is detrimental to many species and may contribute substantially to the loss of regional and global biodiversity has provided empirical justification for the need to manage entire landscapes, not just the components. Comparing the areas of different land-use types between these two periods, human development and landslide enlarged in 2007.
