安徽省杨树主要复合经营模式调查和综合效益分析

Investigation and Comprehensive Benefit Analysis of Main Compound Management Modes of Populus spp. in Anhui Province

在收集文献、实地调查的基础之上,对安徽省杨树主栽区淮北平原、沿江平原主要的复合经营模式进行了深入调研,选取11种典型的经营模式(包括纯杨树林)进行了总结,运用层次分析法对11种经营模式的经济效益和综合效益进行了对比分析,结果表明:各复合经营模式的经济效益和综合效益都高于杨树纯林,其中杨树—姬松茸模式的经济效益和综合效益最高,杨树—小麦(全周期)模式经济效益虽然不高,但综合效益排名第二。建议在沿江平原采取杨树—小麦(全周期)的复合经营模式;在淮北平原采取林粮(经)+林菌或林药的全周期复合经营模式:林分郁闭前,以小麦、油菜及黄豆等农作物为主;待林分郁闭后,可根据具体情况选择开展食用菌或中草药的复合经营,以达到综合效益最大化的目的。

On the basis of documents collection and field investigation,we deeply investigated the main compound management modes of Populus spp. in the Huaibei plain and the riparian plain of Anhui province,summarized 11 kinds of typical management modes（ including pure Populus spp. forest） among them,and comparatively analyzed the economic benefits and comprehensive benefits of these 11 kinds of management modes by using analytic hierarchy process. The results showed that the economic benefits and comprehensive benefits of each compound management mode were higher than those of pure Populus spp. forest. Among various compound management modes,the mode of Populus spp.-Agaricus blazei obtained the highest economic benefits and comprehensive benefits; the comprehensive benefits of Populus spp.-wheat Triticum aestivum（ whole cycle） mode ranked the second,although the economic benefits of this mode were not high. We suggest that： the compound management mode of Populus spp.-wheat（ whole cycle） shall be adopted in the riparian plain of Anhui province; the whole-cycle compound management mode of forest-grain（ economic crop） ＋ forest-edible fungi or forest-Chinese herb shall be taken in the Huaibei plain; before the forest closed,the planted crops shall mainly be wheat,rape and soybean; after the forest closed,the compound management of edible fungi or Chinese herb shall be conducted according to the specific conditions.
