Quantitative Methodologies for Ecotone Determination
生态交错带的定量判定

Ecotone is one of the important features of environmental gradient. Where there is an apparent ecotone along a gradient is a controversy existed in geography and geobotany. However, quantitative determination of its location and width is the basis for studying the ecological process of the ecotone. Transect is an effective methodology to collect non-continual gradient data and to study the structure, function and pattern variation of the ecotones. The most important characteristic of the ecotone is the vari...
