中文摘要：
应用非线性模糊综合评价——未确知测度复合评价模型（简称非线性复合模型）,对云南纵向岭谷区的生态安全进行了评价.非线性复合模型考虑到生态系统的非线性,引入了非线性合成算子,并利用置信度准则对评价样本进行识别与排序.结果表明：非线性复合模型既能反映某种指标的突出影响,又能把线性加权平均模型看作是它的特例;利用非线性复合模型对评价样本进行识别与排序,克服了使用最大隶属度方法进行排序的缺点.非线性复合模型在研究区中的应用得到了客观、合理的评价结果,表明其在多指标、多样本评价中的可行性.
英文摘要：
A complex appraisement model, nonlinear fuzzy comprehensive assessment and unaseertained measure model, was applied on ecological security assessment in Longitudinal Range-Gorge Region of Yunnan Province. Considering the nonlinearity of ecological system, a nonlinear arithmetic operator was introduced in this complex model and appraised swatches were identified and ranked by Reliability code. The results show that this complex model can reflect the significant effect of some dominant indicators, and make weighted average method a particular case. It is better to identify and rank appraised swatches by using unascertained measuring model than maximum degree of membership method. The obtained results of this model in the study area are external and reasonable, showing the feasibility of its application in multi-indicator and multi-swatch assessment.
