基于属性层次-识别模型的重庆市南岸区生态系统健康评价

从复合生态系统的角度，构建自然 社会 经济复合生态系统的城市生态系统健康评价指标体系，并应用属性层次 识别模型建立了城市生态系统健康属性综合评价体系。以重庆市南岸区为例，运用该模型和方法对重庆市南岸区的城市生态系统进行评价，结果表明重庆市南岸区的生态系统属于亚健康类。并根据评价的结果，对影响重庆市南岸区生态系统健康属性的指标进行分析，表明南岸区的城市生态系统正处于过渡阶段，正是城市发展的关键时期，而且其城市生态健康有诸多限制性因素，必须要依靠科学合理的规划和实施方法才能引导城市生态系统向健康的方向发展。为了改善其城市生态系统健康的状况，从长远的考虑，提出了相应的调控措施和方法.

ASSESSMENT OF URBAN ECOSYSTEM HEALTH IN THE NAN’AN DISTRICT OF CHONGQING BASED ON ATTRIBUTE HIERARCHY RECOGNITION MODEL

From the viewpoint of complex ecosystem，an assessment index system of urban ecosystem health was constracted，and an attribute synthetic assessment model was established based on the attribute hierarchy recognize model. Taking the Nan′an District of Chongqing as an example，we use the models and methods to make evaluation for urban ecosystem in the Nan′an District of Chongqing. The results show that the current situation of the ecosystem in the Nan′an District of Chongqing belongs to sub health. In accordance with the results of the evaluation，it analyzes the health evaluation attribute index of the Nan′an District of Chongqing. It shows that the Nan′an ecosystem is in transition phase with a number of limiting factors of health. In order to guide a healthy urban ecosystem development，it must rely on scientific and rational method of planning and implementation. From a long term consideration，in order to improve the urban ecosystem health，corresponding control measures and methods were put forward.
