摘　　要：针对农村生态系统指标体系构建存在随意性、不完备以及重复性等问题,根据农村生态系统结构特性,以能够反映系统间关联性及指标可操作性、简洁性、完备性为目标,构建了农村生态系统健康评价指标体系层次框架,提出了农村生态系统健康评价指标选择模型.并以国家级生态示范县罗山县域农村生态系统为例,运用农村生态系统健康评价指标选择模型,在保证指标体系完备性的前提下,可将该区域农村生态系统健康评价指标由28个优化到18个,结果显示经过优化的指标可满足评价指标选取的可测性、敏感性、可预测性、典型性、可控性、整体性、响应性、稳定性等要求.Focused on the problems of random selection, incomplete and repetitiveness in the ecological indicators selection of rural ecosystem health assessment and according to the structural characteristics of rural eco-system, this paper set up a hierarchy structure of rural ecosystem and constructed an indicators selection model of rural ecosystem health assessment to reflect the correlations between indicators and the operability, simplicity, completeness of the system. Taking rural areas in the Luoshan national-level ecological demonstration for example, the indexes were optimized from 28 to 18 by using the selection model. The result shows that the indexes selected by this model can meet the criteria of measurable, vulnerable, predictable, typical~ controllable, integrative, responsible and stable at all.
