The Evaluation and Decision Analysis of the Agriculture Ecology System in Ludin County/

In order to evaluate the function level of AES and make the optimization of AES construction steps in Ludin county,this paper first analyses the physical conditions and function characteristics of AES there in the present time,and then establishes the layer-structure model of evaluation and deci- sion analysis of AES,at last the function level of AES is evaluated and the optimization of the AES construction steps is elected on the judgement of the matrix calculation by the layer-structure model After all these the following points are concluded:(1) As compared with general standard of slightly below the average,the ecolgical level is a little above the average,and the social benifits and welfare are of the average level.(2) The step should be applied in the Order as D1-D6-D3-D2-D5-D4, if the function level of AES are to be raised in a shortest possible time.
