Stream order, hierarchy, and energy convergence of land use

摘要: The streams in a watershed are organized as network. From an ecological energetic point of view, this hierarchical organization is result the convergence energy. This paper investigates river energy and its relation to hierarchy land use Tansui River Basin. Stream order used rank measure stream position tributaries. transformity relative any particular scale increasing quality. spatial analysis capability GIS calculate distribution accumulated rainfall emergy, geopotential runoff, transformities surface runoff streams. results indicate that corresponds transformity. series increase with successive explains River. pattern land-use also compared As result, Basin correlated supports hypothetical influence on use.
