%X n order to probe the basis of determining orientation for managing the shelterbelt net-works on large scale by measuring and evaluating the spatial pattern of the network in land-scape,the landscape indexes that are appropriate to describe quantity,distribution,and in-tegrity of the networks are studied on the basis of Landscape Ecology.The indexes,ratio ofbelt to patch,dominance,connectivity,and ring,are defined as fitting in with the needs ofmeasuring the spatial pattern of the networks in landscape.The methods are advanced to cal-culate reasonable or existent landscape indexes of the networks by obtaining their structuralparameters respectively from project to construct the networks,and from combining remotesensing with ficld investigation.The way to determine orientation for managing the existentnetworks on large scale is studied in light of result of measuring and evaluating.The applica-tion of the result in the paper is illustrated with example that orientation for managing theexistent networks in Qiangang Town,Nongan County,Jilin province,is given with the helpof measuring and evaluating those spatial pattern.
