摘要
通过对郑州市尖岗水库流域生态健康压力评估指标进行分析,得出尖岗水库流域范围正处于负向演替和生态退化阶段,景观破碎化,重要生境减少,水源涵养功能降低;同时,流域污染排放加剧,物种多样性减少。因此,后续工作应继续采取有效措施阻止环境进一步恶化,促进生态系统结构和功能的恢复。
Through the analysis of the index of ecological health assessment in Zhengzhou city Jiangang reservoir ba-sin, It was concluded that Jiangang reservoir basin was in the range of negative succession and ecological degradationstage, and landscape fragmentation, significant habitat reduction, water conservation function decreased; At the sametime, the pollution discharge of the river basin was intensified, and the species diversity was reduced. Therefore, follow-up work should continue to take effective measures to prevent further deterioration of the environment, and promote the recovery of ecosystem structure and function.
