摘要/Abstract

摘要： 应用层次分析法,对南埂江滩林农复合生态系统不同调控模式与芦苇模式的经济、生态、社会以及综合效益进行评价.结果表明,滩地上建立的林农复合生态系统———“抑螺防病林”,各效益均显著高于原来的芦苇系统,是治理与开发有螺滩地的有效途径.对于林农复合生态系统不同调控模式而言,经济效益,块状皆伐模式最高,不伐模式第二,其它4种间伐处理模式相对较低且相互之间差异不大;生态效益,各模式之间较为接近,无明显差别;社会效益,块状皆伐模式最高,不伐模式最低,其它4种间伐处理模式居中;综合效益,各模式之间的大小顺序与经济效益相似.块状皆伐为最佳模式.对于包括块状皆伐在内的5种间伐调控模式,进一步提高其效益的关键是选择经济价值、特别是产投比高的植物栽培品种;对于不伐模式,继续进行林下间种,是提高该模式社会效益和综合效益的有效措施.

Abstract: The economic,ecological,social and comprehensive benefits of different regulation models of agroforestry ecosystem in Nangeng river beach were evaluated by AHP.The resuls showed that agroforestry ecosystem was significantly superior to reed(Phragmites communis)system.Different regulation models of agroforestry ecosystem had different benefits.The sheet-thinning model had the highest economic,social,and comprehensive benefits,and it was the optimal regulation model.For all thinning models,the key approach to further raise benefits was to choose some intercrop variations,which had a high economic value,especially a high ratio of output to input.For no-thinning model,keeping on intercropping was the effective measure to raise the social and comprehensive benefits.
