Abstract:: This paper constructs assessment index system of agricultural soil and water resources development and utilization,and brings forward quantificational assessment method.It confirms the index weight primary using the Analytic Hierarchy Process(AHP),then revises it basing the communication degree showed output entropy of the various indices,and confirms the obstacle ranking impacting regional soil and water resources high-efficient utilization by calculating’obstacle degree’ of indices.The results show that the comprehensive assessment value of agricultural soil and water resources development and utilization of Weijiagou small watershed is 61.07,the obstacle ranking of the soil and water resources high-efficient utilization is soil and water loss control rate,vegetation cover,water productivity,soil erosion modulus etc.For the future strengthening soil and water loss control,developing water saving irrigation and increasing agricultural integrate technical level should be the prior measure in this small watershed.
