| Abstract: | This paper analyzed and compared the productivity and tree growth law of 20 year old 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. |
