STRATEGIC ENVIRONMENT ASSESSMENT ON LAND-USE PLANNING-A Case Study of Changchun Economic and Technological Zone

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.
