Abstract

Abstract: Liaohe River delta can be divided into three ecolomic regions and eight subregions bymeans of principal component analysis and cluster analysis. The function situation of its agricultural ecolomic system is evaluated through the analysis of three attributes reflectingthe functions of it.

Key words: Liaohe River delta, Ecolomic division, System function analysis, litter, total soil nitrogen, vegetation types, soil organic carbon, fine root
