基于粗糙集的湿地景观质量评价研究——以重庆市阿蓬江国家湿地公园为例

Study on evaluation of wetland landscape quality based on rough set

文章旨在构建湿地景观评价指标体系,在国家规定的科学价值、整体风貌、科普宣传价值、历史文化价值和美学价值5个一级指标的基础上提出了29个二级指标。利用粗糙集理论,对29个二级指标进行筛选,最终在每个一级指标的基础上筛选出二级指标各3个,分别是科学价值:物种多样性、遗传多样性、科研教学价值;整体风貌:结构复杂性、与周围环境协调性、区位条件;科普宣传价值:宣传范围、宣传场馆、宣传次数;历史文化价值:历史人物、历史事件、文化底蕴;美学价值:幽深度、开阔度、视觉多样性。构成一套较完整的拥有一级指标5个,二级指标15个的湿地景观质量评价指标体系。并对阿蓬江湿地景观进行评价,其最后得分值为8.17,质量等级为优秀。

In order to set up a wetland landscape evaluation system, according to five first-level indicators such as scientific value, integral style, science propaganda value, historical and cultural values and aesthetic value, 29 secondary indexes were put forward. Then the 29 secondary indexes were filtered by using rough set theory. Finally, 3 secondary indexes were picked respectively up from each first level index, so there were 15 indexes to be selected out such as species diversity, genetic diversity, scientific research and teaching value, structure complexity, surrounding environment coordination, location conditions, scope of propaganda, propaganda venues, amount of propaganda, historical figures, historical events, culture, deep degree, open degree, visual diversity, which make up a set of relatively complete wetland landscape quality evaluation index system（five first level indexes and fifteen secondary indexes）. By using the wetland landscape evaluation system, Apengjiang wetland landscape in Chongqing was evaluated, the final score of Apengjiang wetland landscape was 8.17, whose quality grade is outstanding.
