| 摘 要： | 云南楚雄龙川江流域上游的水库建设和河道渠化等工程改变了河谷盆地、缓坡、农耕地、河道、间歇性河流湿地和季节性溪流的地形和水文条件,曾经支持健康河流生态系统的间歇性湿地大面积退化,导致河流自净能力下降、植被退化以及生物多样性降低。通过调查和评估龙川江湿地,分析间歇性河流湿地生态修复的轨迹,确定修复目标、参考模型和技术路线,并制定湿地管理计划,旨在恢复健康的河流湿地环境。在湿地修复措施方面,挖掘和重新连接关键生态属性的湿地斑块,通过间歇性湿地保留雨水和流域的径流水量,实施综合种植计划,在河岸两侧恢复具有重要生态意义的季节性湿地综合体等。

| Abstract: | The Longchuan river basin in Chuxiong,Yunnan consists of a series of valley basins,gentle slopes,farming land,river canals,intermittent river wetlands and seasonal streams.As the construction of upstream reservoirs and canalization of the streams have changed the original topography and hydrological conditions,the intermittent wetland of the river ecosystem is degraded on a large scale,which leads to the decline of the river's self-purification capacity,the degradation of vegetation,and the reduction of biodiversity.Through the investigation and evaluation of the Longchuan River wetland,this paper clarifies the trajectory of the ecological restoration of the intermittent river wetland,determines the restoration goals,reference models and technical approaches,and formulates a wetland management plan to restore the whole river wetland environment.Measures include excavating and reconnecting wetland patches with key ecological attributes,retaining rainfall and runoff from its basin through wetland depressions,implementing comprehensive planting plan,and restoring seasonal wetland complexes of significance on both sides of the river banks. |
