生物坝护岸造田与效益分析

Farmland-building on ecological dams and benefit analysis

昔日一年一场风,从春刮到冬,白天点油灯,夜晚土堵门的不毛之地,如今变成绿染山川、碧波清风的“塞上绿洲”,已成为晋西北地区的生态旅游胜地。这便是生物坝工程对治理水土流失、改变生态环境的贡献。经多年对右玉县生物坝工程观测和调查,分析了其原理及效益,对流域沿岸及支流合理的造田营造方式做出了评价。

The creation of ecological dams in the Northwest of Shanxi Province turns the formal barren land into farmland, which makes great contribution to erosion control and improvement of ecological environment. After many years of observation and investigation to the ecological dams in Youyu County, its operation result and benefits are examined. Assessment is made on the proper method of farmland creation along the banks of river or tributaries.
