昆明北郊水源保护区圣诞树人工林分生物量及生产力的研究
刘文耀;

摘要:
昆明北郊松华坝水源保护区10年生圣诞树人工林分生物量为137.926t/hm2,净生产量为24.128t/hm2·a,其中乔木层生物量为130.418t/hm2,净生产量为19.369t/hm2·a,下木和草本植物生物量和净生产量分别为0.935t/hm2和0.609t/hm2·a,枯枝落叶层现存量和林分凋落物量分别为6.573t/hm2和4.150t/hm2·a。在林分产量结构方面,10m以下树干生物量占其总量的98.37%,4~12m之间枝、叶生物量分别占整个枝、叶生物量的85.51%和94.90%,地下根系在离地面20cm深土层内的生物量占总根量的73.04%。目前,该类林分群落结构不合理,整体效应较差,保持水土作用未能充分发挥出来。应及时进行间伐,调整群落产量结构;注重对林下地被植物及枯枝落叶层的保护,以提高其综合效益。
