摘要
从水生态韧性概念出发,结合国内外相关研究成果提出水生态韧性研究的发展方向。将DPSIR模型与社会—生态韧性相结合构建水生态韧性评价体系,选取涵盖人工生态系统和自然生态系统的18个评价指标;采用改进的级差最大化组合赋权法确定评价指标的主客观组合权重。以中国31个省份为研究对象进行评价,研究发现2008—2018年间中国水生态韧性得到了提升。进一步分析2018年评价结果后发现,驱动力、压力、状态、响应准则层是影响中国水生态韧性的重要方面,水网密度指数和湿地率是影响中国水生态韧性的代表性评价指标。根据水生态韧性总体分析和代表性评价指标分析结果,研究提出制定总体指导方针,划定流域水生态系统功能区,划分中国湿地保护修复区,优化中国城镇体系等4方面的优化战略思考。为完善我国水生态系统的规划体系提供理论支持,为实现我国水生态系统的可持续发展提供技术保障。
From the perspective of water-ecological resilience,the research directions of water-ecological resilience could be proposed based on literature review.Water-ecological resilience evaluation system could be built by combining DPSIR model and social-ecological resilience.18 indicators which belong to artificial and natural ecosystems were selected.Weight of indicators could be calculated by using improved level difference maximization combination weighting method.Based on the evaluation of China,the research found that the water-ecological resilience in China has improved during 2008 and 2018.After further analysis of the 2018 evaluation results,the research found that driving force,pressure,state,response are important aspects that affect water-ecological resilience of China.Density index of water network and wetland coverage are representative indicators that affect water-ecological resilience of China.General guidelines,water ecosystem functional area of river basin,wetland protection area and urban system could be put forward based on the analysis of results.The research provides theoretical support for water ecosystem planning system and technical support for water ecosystem sustainable development.
