闽东南丘陵区水土保持生态景观模式的构建与实践——以霞美示范区为例

The Construction of the Model of Soil And Water Conservation Eco-Landscapein South-east Areas of Fujian Province——The Case Study in Xiamei Demonstration Area

本研究以福建霞美为实例,构建了示范区水土保持生态景观模式,并取得显著的生态、经济和社会效益。提出区域水土保持生态景观是一个有机整体,必须依据坡面径流调控理论,把水土保持措施结合到农业措施中去;指出在侵蚀坡地上重建植被,必须注重近地表林下植被的建设,避免造成“空中绿化”现象;要充分考虑地带性规律对群落的影响,合理地配置先锋植物群落,以免造成群落退化。构建的示范区水土保持生态景观模式、方法和理论在闽南乃至我国南方有借鉴意义。

The model of soil and water conservation eco- landscape has been established in the case study area of Fujian Xiamei, which has produced greatly benefits including ecological, social - economic impact. The study result showed that the regional soil and water conservation eco- landscape should be reviewed as a whole system and the control measures should be integrated into the farming systems based on runoff control theories. The methods of farmer- participating and down- up have been adopted in the study project. It is suggested that the grass vegetation growth should be focused when rebuilding plant community on eroded slopes. It＇ s pointed that the influence of the zonality rule upon vegetation rebuilding on eroded slopes should be considered. The model, methods and theories of the construction of soil and water conservation eco - landscape in the case study areas are worthy to other areas.
