鄂西南退耕还林6种经营模式综合效益评价

Overall Benefit Evaluation on Six Management Models of 'Green for Grain' Forestry Engineering in Southwest Hubei Province

对鄂西南退耕还林中的厚朴+箬竹、密植茶园、杉木+毛竹、杉木+桤木、香椿纯林、日本落叶松纯林6种经营模式,用层次分析法进行生态效益、经济效益、社会效益3大指标的综合评价。结果表明:综合效益由高至低排序为厚朴+箬竹模式(密植茶园模式(杉木+毛竹模式(杉木+桤木模式(香椿纯林模式(日本落叶松纯林模式。

A comprehensive evaluation was made by AHP methodology on the ecological, economic and social benefits of six forest management models that were summarized from the ＇ Green carried out in the southwest part of Hubei Province, i.e. , Mangnolia officinalis for Grain＇ Forestry Engineering ＋ lndocalamus tessellatus, dense tea plantation, Cunninghamia lanceolata ＋ Phyllestachys pubescens, Cutminghamia lanceolata ＋ Alnus glutinosa, pure Toona sinensis plantation, and the pure Larix kaempferi plantation. The results showed that the comprehensive benefits of the six models were ranked in the order as Mangnolia officinalis ＋ lndocalamus tessellates 〉 dense tea plantation 〉 Cunninghamia lanceolata ＋ Phyllestachys pubescens 〉 Cunninghamia lanceolata ＋ Alnus glutinosa 〉 pure Toona sinensis plantation 〉 pure Larix kaempferi plantation.
