中文摘要：

选取滇西北高原典型退化湿地纳帕海,对比植被恢复前后入湖河流廊道、草甸（汇水过渡区）、湖滨带植物群落物种的组成、水质、土壤有机质和全氮含量的变化,分析流域完整尺度恢复实践的有效性.结果表明：研究区湿地植物在恢复初期由8科12属13种迅速增加至18科22属28种;地上生物量从318.56g·m-2上升到507.68g·m-2;湖滨及河流岸带植物群落恢复前后变化明显,耐污种逐渐减少或消失,出现了消失多年的沼泽植物黑三棱和水毛茛群落;土壤有机质和全氮含量分别由恢复前的28.85和0.79g·kg-1增加到50.26和1.45g·kg-1,水体中的TN、TP和COD含量较恢复前显著下降,去除率分别达到67.9%、79.2%和71.2%,水体透明度提高了179%,湿地生态系统结构和功能得到了改善和恢复.在高原闭合半闭合湿地区,采取植被恢复措施及其技术方法行之有效.

英文摘要：

Selecting the restoration site of Napahai, a representative degraded wetland in Northwest Yunnan Plateau, as test object, a comparative study was made on the changes of plant community species composition, water quality, and soil organic matter （OM） and total nitrogen （TN） contents within stream way, meadow, and lakeside before and after vegetation restoration, aimed to verify the effectiveness of integrated ecosystem restoration at catchment scale. In the early restoration period, the plants at the study site increased from 13 to 28 species, 12 to 22 genera, and 8 to 18 fami- -2 m-2. lies, and the aboveground biomass increased from 318.56 g · m to 507.68 g . The plant community structure and composition in lakeside and riverside had an obvious change before and after the vegetation restoration. Pollution-tolerant species diminished or disappeared, while the primary swamp communities of Sparganium stoloniferum and Batrachium bungei appeared after their disappearance for many years. After vegetation restoration, soil OM and TN contents increased from 28.85 g·kg-land0.79 g-kg-1 to 50.26 g- kg-1 and 1.45 g. kg-1, respectively. TheTN and TP contents and COD in the water decreased significantly, and their removal rates reached to 67.9% , 79.2%, and 71.2%, respectively. The transparency of water body increased to 179%, indicating that the structure and function of the wetland ecosystem had been substantially improved and restored. It was concluded that the vegetation restoration measures and technology used in closed or half-closed plateau wetland area were effective.
