辽西地区几种农林复合型水土保持林模式的研究

Based on the principles of ecological economics and ecological optimum, the management techniques of soil and water conservation forest with four management models,i.e. agroforestry, forest herbs, forest medicinal crops and forest fruit trees were studied in western Liaoning. The results showed, not only the high economic benefit, but also the ecological and social benefit will be achieved. If four models are used with combination, it will be a good way to transform the soil and water conservation forest in western Liaoning.
