摘要
结合不同时相遥感影像和实地调查,借助RS和GIS技术,研究了2005年～2010年大九湖湿地土地利用的动态变化和类型转换,以探讨生态恢复工程对土地利用格局的影响.研究发现,生态恢复工程实施后,湖泊和草甸面积大幅增加,菜地和旱地面积大幅减少;土地利用类型转化主要表现为沼泽、草甸、林地向湖泊转化和菜地、旱地向草甸转化.大九湖湿地生态恢复工程取得了初步成效,湿地类型和面积有所增加,湿地景观得到一定恢复,湿地生态环境有所改善.针对沼泽湿地面积减少的现状,需要加强对泥炭藓沼泽湿地的恢复和保护,规范对泥炭藓湿地的开发、经营和管理行为,最终实现湿地生态环境的可持续发展.
In order to discuss the effect of ecological restoration on land use pattern, this paper studies the land use change and transition of Dajiuhu wetland from 2005 to 2010 by using two temporal satellite images of remote sensing and field surveying and applying RS and GIS technology. The results show that after the implementation of Dajiuhu Wetland Protection, Restoration and Park Construction Project （WPRPCP）, the areas of lake and meadow have increased greatly, while that of vegetable land and upland have decreased substantially; the land use transitions are mainly from swap, meadow and forest land to lake, and from vegetable land and upland to meadow; indicating that Dajiuhu WPRPCP has achieved initial success with the types and areas of wetland having increased, the landscape of wetland being restored and the ecological environment being improved to some extent. Response to the reduction of marsh wetland, we should strengthen the restoration and protection of sphagnum marshes wetland, standardize people＇s behavior in developing, operating and managing sphagnum marshes, and finally realize the sustainable development of wetland ecological environment.
