摘要
三峡库区森林覆盖率低,水土流失严重。三峡工程兴建后,由于大量耕地被淹,移民后靠,库区的生态环境与移民经济之间的矛盾将会更加突出。本文提出了经济植物复层栽培方法,对其在减少库区水土流失、改善库区生态环境和解决库区移民经济方面的作用作了全面的论述。经济植物复层栽培是解决三峡库区生态环境和移民经济的基本途径,采用扩大种植农作物的方法来解决三峡库区移民经济问题将会加剧水土流失,使生态环境更加恶化。
Land Submergence and population resettlement will occur with the construction of the Three-Gorge Electric Power Project.The ecological environment in this area would be worsening ifcorresponding countermeasures are not taken. This paper puts forward a new proposal whichmaintains the cultivation of econmic plants to constitue complex economic forest systems in order to comtrol soil and water loss and to develop resettlement economics.Planting farm crops should not be advocated in this area to avoid aggravating soil and water loss. The advantages ofsuch systems with reference to soil kand water conservation and resettlement econmics in the reservior area are discussed.
