摘要降解C. Naivasha湖的纸莎草（papyrus）是湖泊水位下降和大型放牧哺乳动物、布法罗和牛以及几个较小物种的破坏的结果，此外还有更有限的人类直接清除。恢复纸莎草被认为是非常重要的未来湖泊生态系统的可持续性。纸莎草（湿地）恢复提出了两种不同的干预措施：一个位于Malewa河三角洲周围，基于生态水文学原则，另一个在Gilgil河附近的土地上，采用更多的生态工程方法。这两种干预措施在生态上都是可行的。然而，这两个项目的主要局限性都与人为因素有关，在这方面，恢复Gilgil河被认为是目前两个提案中更务实的一个。今后的行动应促进当地社区参与奈瓦沙湖的任何恢复项目，特别强调开发可从纸莎草沼泽中获得的经济产品。
Abstract Degradation of C. papyrus (papyrus) at Lake Naivasha is the result of a combination of lowered lake levels and destruction by large grazing mammals, buffalo and cattle, followed by several smaller species, in addition to more limited direct human clearance. Restoration of papyrus is considered to be of great importance for the future sustainability of the lake ecosystem. Two different interventions for papyrus (wetland) restoration have been proposed: one located around the delta of the Malewa river, based on ecohydrological principles, the other on land adjacent to the Gilgil river, adopting more of an ecological engineering approach. Both interventions are ecologically feasible. However, the principal limitations of both projects relate to anthropogenic factors and, in this respect, restoration of the Gilgil river is regarded as the more pragmatic of the two proposals at the present time. Future action should facilitate the involvement of local communities in any restoration projects at Lake Naivasha, with particular emphasis placed on the development of economic goods derivable from papyrus swamps.
