山丘区抑螺防病林效益评价

Benefit Evaluation of Snail and Disease Prevention Forests in Hilly Areas

根据林业血防作用机理及林分模式特点,采用层次分析法,以抑螺效果、经济效益、生态效益、景观效果和林木生命周期为类目标层构建了山丘区抑螺防病林综合效益评价体系;对34种纯林模式综合效益的评价结果显示:最高的是经济型,其次为兼用型,最低的为用材型。

According to the mechanism of forestry schistosomiasis prevention and the characteristics of stand models,the benefit evaluation system was extablished for forest of snail control and disease prevention in hilly areas by the analytic hierarchy process with five target layers,such as anti-snail effect,economic benefit,ecological benefit,landscape effect and forest lifetime.And the evaluation results of comprehensive benefits of 34 pure forest models showed that the highest was economic type,followed by dual-use type,and the lowest was timber type.
