云南省大理市环洱海湖滨生态廊道生态景观规划研究

Study on Ecological Landscape Planning of Ecological Corridor Around Erhai Lake in Dali City

以恢复生态学和景观生态学理论为基础,以“人退湖进、分区分类、多层修复”的理念为指导,以湖滨缓冲带生态修复和湿地建设为主要任务。在对环洱海湖滨缓冲带及周边环境充分调研的基础上,结合各区地形地貌、水文气象、土壤植被等特征分析湖滨缓冲带存在的问题,分区分类开展生态修复及湿地工程、生态监测廊道工程、生态搬迁工程及带有湿地修复科研功能的试验地工程,因地制宜采取多类型生态修复工艺、湿地建设工艺,制定各区、各段、各点的生态构建与恢复、低污染水截蓄与净化、市场化机制,并构建缓冲带上生态监测管理站点和科技技术支撑研究基地,为洱海生态保护核心区提供系统的生态安全屏障,最终达到环洱海流域湖滨缓冲带生态系统的自我维持和良性循环状态。

Based on the theories of restoration ecology and landscape ecology,this paper is guided by the concept of"people moving away,lake restoration,zoning and classification,multi-layer restoration",and takes the ecological restoration of lakeside buffer zone and wetland construction as the main task.Based on the investigation of the lakeside buffer zone around Erhai Lake and its surrounding environment,combined with the characteristics of landform,hydrometeorology,soil vegetation and so on,this paper analyzes the problems existing in the lakeside buffer zone,and carries out ecological restoration and wetland project,ecological monitoring Corridor project,ecological relocation project and experimental site project with wetland restoration and scientific research function.According to local conditions,adopt various types of ecological restoration processes and wetland construction processes.Formulate ecological construction and restoration,low pollution water interception,storage and purification,and market-oriented mechanisms in different regions,and build ecological monitoring and management stations and scientific and technological support research bases on the buffer zone.Provide a systematic ecological security barrier for the core area of Erhai ecological protection,and finally achieve the self-sustaining and virtuous cycle state of the lakeside buffer zone ecosystem around Erhai Basin.
