三峡库区消落带土地生态友好型利用——以种植桑树为例

Eco-friendly Utilization of Land in Water-fluctuation Belt of the Three Gorges Reservoir Area—Growing Mulberry as an Example

近几年三峡库区消落带土地农用化使得其原本脆弱的生态环境进一步恶化,选择兼具生态价值和经济价值的树种开展消落带植被恢复,是从根本上解决消落带环境问题的理想方案。通过对三峡库区170~175 m高程区消落带种植桑树的经济效益和生态效益进行调查与分析,认为在库区消落带土地种植桑树,可以在促进生态环境建设的同时,增加库区农民的经济收入,最终实现库区生态、经济和社会的可持续发展,是库区消落带土地生态友好型利用模式。

In recent years, land farming in water-fluctuation belt of the Three Gorges Reservoir area has further deteriora- ted the fragile ecological environment in that area. Growing trees with both ecological and economic values to carry out vegetation restoration in the water-fluctuation belt is an ideal and fundamental solution to solve this environmental problem. Through investigating and analyzing the economic and ecological benefits of growing mulberry in 170-175 m el- evation zone of the Three Gorges Reservoir area, it is concluded that growing mulberry trees in water-fluctuation belt of the reservoir area could not only promote establishment of ecological environment, but also improve the economic income of local farmers, which would ultimately allow sustainable development of ecology, economy and society, being an eco-friendly pattern for land use in water-fluctuation belt of the reservoir area.
