Shape and color characteristics were used to form the separated pattern vector and RBF network was used as classifier for each pattern. Each classifier was linearly combined to give the final identification result. Shape pattern consists of rectangularity, elongation, roundness, sphericity, lobation and seven movement invariants. R, G, B, L histogram and R.G chromaticity histogram were treated as separated color characteristic vector.

The framework established was practical and universal, and could provide abase for specific area to select its assessment indicators. The operable indicatorsystem developed which synthetically reflected the sustainable development status ofliling could fill up the blank of regional sustainable development evaluation in liling,and this work was of practical and strategic significance to a certain extent. Inallusion to the flaw existed indimensionlessness of original data in grey system,mean value method was adopted instead of traditional standardized method, and theguidance for confirming the direction of eigenvector was first brought to grey systemin the application of sustainable development evaluation aimed to increase theobjectivity and accuracy of evaluation. The evaluation results on liling could supplybeneficial references for decision makers to make and adjust sustainabledevelopment strategic goal and counter measures.
