Abstract
The study centers on the necessity, the workflow and the synthetically integrated methods (Principal Component Analysis(PCA), AndyticalHierarchyProcess(AHP) andFuzzy ComprerhensiveEvaluation(FCE)) of strategic environment assessment (SEA) on land-use planning. The whole article includes three main parts: firstly, some attribute database, graphic-base and the spatial transform matrix, which reflect the change of regional land-use pattern, can be obtained by GIS technique; secondly, adopting fitting method of trend-surface analysis will convert environment monitoring data from scattered spots to regular control spots, based on which we can perform regional environment impact assessment; finally, Changchun Economic and Technological Developmen Zone is chosen as a case study on land-use planning.Through those efforts the results may be obtained as follows: 1) according to transform matrix, the possibility of transformation from one land-use to another can be obtained after the planning is carried out; 2) environment quality would change as a result of the change of land-nsc pattern; 3) the SEA on land-use plan is an effective tool to make land-use pattern more reasonable.
