基于熵权的黄河湿地自然保护区生态环境演变特征研究
- 分享到:
摘要：
研究聚焦河南黄河湿地国家级自然保护区生态环境演变特征，采用熵权法分析生态系统发展质量和稳定性,计算得到自然保护区生态发展指数(ecology development index,EDI),定量研究了自然保护区生态环境演变特征.结果表明.各项指标的熵权和单一年度的指标权重结构均随时间呈现动态变化,系统中各项指标的重要性并非恒定不变.2006至2023年研究区内生态发展指数EDI范围为26.92~46.49,2012年之前整体偏低,2013至2020年之间整体呈现稳中有升的趋势，2021年之后略有下降，总体呈现稳定一增长的变化趋势，表明近年来保护区内生态环境整体向好.
The evolutionary characteristios of the ecological environment in the Yellow River wetland nature reserve were focused on, the development qualitiy and stability of the ecosystem were analyzed based on the entropy weight method, the eco-logical development index(EDI) was calculated, the ecological environmental evolution characteristics of the reserve in recent years were researched. The results showed that, the entropy weights of varrous indicators and the weight structure of indicators in any single year exhibited dynamic changes over time, the importance of individual indicators within the system was not con-stant. From 2006 to 2023, the EDI of the nature reserve ranged from 26.92 to 46.49. Values were generally low prior to 2012,showed a steady inerease overall between 2013 and 2020, and experienced a slight decline after 2021. Overall, the index pres-ents a stable-growth trend, signifying an overall improvement in the ecological environment within the reserve in recent years.
