摘要: Vegetation boundaries such as riparian zones or forest stand edges are inherent features of landscapes that play more than one functional role in terrestrial ecosystems dynamics (Hansen and Di Castri 1992). The delineation ecotones (i.e., boundary areas), either sharp gradual, between adjacent vegetation communities is important several aspects land use management planning (e.g., the stands for estimating wood volume available harvesting). location accuracy delimited boundaries, however, depend on spatial temporal resolution data well subsequent statistical methods used to detect them. In context delineation, various types field data, aerial photographs remotely sensed images) available. type determines which edge detection methods, photointerpretation, filter kernels) should be used. Accuracy delineated therefore depends both sensitivity methods.
