摘    要: 为探索小流域生态经济系统健康模式,在分析东北低山丘陵区黑牛河小流域现状及特征的基础上,对该区小流域生态经济系统的健康状况进行定量诊断评价。选择31个因素作为参评因子,建立诊断指标体系;运用熵技术支持下的AHP法确定指标权重,选用模糊隶属函数进行指标量化,线性加权函数法建立各级诊断模型,诊断评判出小流域系统健康水平;引进“障碍度”“优势度”等概念进行病理障碍和优势诊断,并针对主要障碍因素和优势提出了小流域健康发展的具体对策与建议。

关 键 词:健康诊断  指标体系  障碍度  优势度  东北低山丘陵区  小流域

Abstract:Taking the small watershed of Heiniuhe as an example,based on the analysis of the present situation and characteristics of small watershed,the health status of eco-economy system in the small watershed of the region is quantificationally diagnosed and evaluated.31 factors were selected as evaluating factors to build the diagnosis index system.The method of AHP which were supported by the entropy technique was applied to fix the weight of index.The system health level is judged by integration diagnose which uses the fuzzy membership function and the linear weighted function.The conception of "Obstacle degree" and "Advantage degree" were introduced to apply the pathology obstacle and advantage diagnosis,and according to the main obstacle factors and advantages.The specfic countermeasures and suggestions were put forward for healthy development of small watershed.
Keywords:health diagnosis  index system  obstacle degree  advantage degree  hilly region of northeast China  small watershed
