中文摘要：

在分析生态经济系统健康特征和指标筛选原则的基础上，构建了一套适合于县域尺度生态经济系统健康诊断指标体系。并运用层次分析法，采用了精度较高的均方差法确定指标权重，运用递阶多层次综合法和线性加权函数法建立了时间尺度上的农林复合生态系统综合评价模型，以县为单元，研究了红壤丘陵区县域多年农林复合生态经济系统健康情况。研究结果表明：研究区1980～2005年生态经济综合健康稳定水平呈逐年上升趋势，经济健康性方面是逐年平稳上升，社会健康性是波动性上升，而资源环境健康性则是先升后降，然后是相对稳定。引入障碍度概念，进行健康障碍诊断。分析结果表明1991年以前障碍因子主要是经济指标，1997年后障碍因子主要是资源环境指标。

英文摘要：

Based on the anal indices,a set of diagnose in ysis of the eco-economic system health dices of eco-economic system in county characteristic and sifting principle of 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 multihierarchical 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 ecoeconomic 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.
