Diverse boundaries between patches within the sandy landscape in Mu Us sandy land

Abstract

Abstract: A terrestrial landscape is a mosaic of heterogeneous landforms, vegetation types, and land uses. Boundaries between neighbor patches become conspicuous components of ecological landscapes. The vegetation cover, plant species number, species similarity, soil organic Ccontent, and soil organic N content crossing neighbor patches in Mu Us sandy land were investigated. The results showed that boundaries determined on the basis of each parameter differed, which compared favorably with the previous studies on ecotone dynamics and ecological boundaries delineation.

Key words: Patch, Boundary, Sandy landscape, Mu Us sandy land, soil water and salt movement, quality, arid area of Southern Xinjiang, cotton yield, irrigation regime, mechanically-harvested cotton
