摘要
本文分析比较了２０年生杉木与酸枣人工混交林以及杉木纯林、酸枣纯林生产力和林木生长规律。结果表明：杉木与酸枣人工混交林乔木层生物量为１６８．７４ｔ／ｈｍ２＞杉木纯林乔木层生物量１３５．９５ｔ／ｈｍ２＞酸枣纯林乔木层生物量１０７．０１ｔ／ｈｍ２；杉木与酸枣混交林林分蓄积量为３５５．１１３ｍ３／ｈｍ２＞杉木纯林蓄积量３０１．６７２ｍ３／ｈｍ２＞酸枣纯林蓄积量１７３．１５０ｍ３／ｈｍ２；杉木与酸枣混交可改变树种单调状况，防止地力衰退，提高林地生产力。
This paper analyzed and compared the productivity and tree growth law of 20yearold artificial mixed forest of Cunninghamia lanceolata and Choerospondias axillaris,pure forest of Clanceolata and pure forest of Caxillaris ,The results indicate that the arbor layer biomass of the artificial mixed forest of C.lanceolata and C.axillaris,the pure forest of C.lanceolata and the pure forest of C.axillaris is 168.74t/hm2,135.95t/hm2 and 10701t/hm2 respectively;the stand stocking of the above forests is 355.113m3/hm2,301.672m3/hm2 and 173.150m3/hm2 respectively;and the mixture of C.lanceolata and C.axillaris may change the monotonous tree species situation,prevent the soil fertility reduction and increase the forest land productivity.
