| 摘 要： | 以河南省民权县农区林业为对象，全面系统地分析了民权县农区林业的生态、经济和社会效益。据１９９１年调查，全县立木总资产７１５６．８１万元，立木年增值１９１１．５３万元；１９９１年全县林业总产值９９７６．８４万元；林业商品率５７．８％；林业直接为１．２３万人提供了就业机会。农区林业可以改善农田小气候；农林间作生物量比单纯农地提高５％～２０％，光能利用率提高了５％～２０％。直接为农用积肥提供了基质１．７６１万ｔ；和１９４９年相比，扩大耕地１５１２０ｈｍ２；生态条件改善使农业产值增加３４２４．４万元。民权林木为畜牧提供粗饲料１．３８５１万ｔ，为整个牧用粗饲料的２１．９５％，对畜牧业收入的贡献率为３２．６７％，可增加畜牧业产值３１２８万元；全县养蜂产值２９９万元；对畜牧业贡献率为３５．０８％。村社林可以改善人畜的生态环境；减少医药费开支６２６．８９万元。
