摘　　要：以桂东南梧州市龙圩区下小河流域花岗岩崩岗侵蚀区为例,以水土美丽绿色空间为基础、小流域生态观光旅游为特色,总体统筹规划设计区域景观空间布局和规划方案,结合生态恢复、经济生产、休闲旅游、文化展示的功能需求,将其划分为生态保护区、景观茶园区、水保科普区、特色花海区、观光农业区、乡村聚落区六大区域。根据研究区地形、植被状况、各类用地性质以及景观资源状况,通过地形改造、植被绿化、梯田建设等一系列工程与生物措施,对崩岗各部分进行生态设计,并从植物、水体、道路、配套设施等方面对崩岗侵蚀区进行空间优化,保护水土资源,发展崩岗生态旅游。将崩岗水土保持治理工作与景观生态设计相结合,在传统的崩岗综合治理模式下,兼顾山地、农田等其他水土流失治理工作,将崩岗旅游与农业观光旅游、乡村旅游相结合,探索更全面的可持续发展崩岗侵蚀区综合治理模式。Taking the granite collapsing gully erosion area in the Xiaxiaohe watershed in Longwei District,Wuzhou City as an example,based on the beautiful water and soil green space,featuring small river basin ecological sightseeing tourism,we carried out overall planning and design of the regional landscape space layout.Considering on ecological restoration,economic production,leisure tourism,cultural display functional requirements,this area was divided into six parts:ecological protection area,tea park,soil and water conservation science area,featured flower area,sightseeing agricultural area and rural settlement area.According to the terrain,vegetation status of the area,the nature of land use and landscape resources,through a series of engineering and biological measures such as terrain reconstruction,vegetation greening,terrace construction,etc.,ecological design was carried out on collapsing gully,and space optimization of landslide erosion areas from aspects of plants,waters,roads,and supporting facilities,which is to protect water and soil resources and develop collapsing gully ecological tourism.According to the traditional harness model of collapsing gully s comprehensive treatment,this article combined collapsing gully governance with landscape ecological design,and gave consideration to other soil erosion control works such as mountains and farmlands,combining tourism collapsing gully with agricultural sightseeing tourism and rural tourism to explore a more comprehensive and sustainable development model of collapsing gully governance.
