Abstract:

Based on the analysis of the ecoeconomic system health characteristic and sifting principle of indices,a set of diagnose indices of ecoeconomic system in county dimension was established.Using the analytic hierarchy process,adopting mean square deviation of higher accuracy index weight,the agriculture and forestry compound ecosystem overall evaluation model has been established by applying multihierarchical synthesis method and the linearity adds weightingfunction method on time dimension.Taking the county as the unit,ecoeconomic system healthy situation of farming and forestry compound of county territory has been studied in the laterite rolling region.Study result indicates that the healthy of ecoeconomic system is an upward tendency year by year from 1980 to 2005,economy health aspect is rising steadily year by year,society health is rising with fluctuation,but resource environment health is descend after rising first,and then is relatively stable.Leading into the barrier concept,the healthy obstacle diagnose is carried out.The result shows that the obstacle factor is economic indices mainly before 1991,resource environment indices mainly after 1997.

Key words: health evaluation, agroforestry ecoeconomic system, county territory, laterite rolling region
