摘要

以长汀县花岗岩强度侵蚀区采用的全坡面播草和多树种混交两种治理措施为研究对象

以未采取恢复措施的严重侵蚀地(对照1)及当地植被保留较好的风水林(对照2)为对照

探讨了这两种措施对群落植被的生物量和生产力的恢复效果。结果表明

全坡面播草和多树种混交群落的马尾松平均木生物量分别为23.03和23.13kg

均显著高于对照1(6.02kg)

均显著低于对照2(582.87kg)。全坡面播草群落的生产力较低

为5.30t/(hm

.a)

恢复度为0.40

群落生物量为26.20t/hm

恢复度为0.10。多树种混交群落生产力较高

为9.19t/(hm

.a)恢复度为0.78群落生物量为36.98t/hm

恢复度为0.16。二者的生物量和生产力的恢复程度差异较大

体现了不同措施的恢复效果。

Abstract

The research was carried out in the severely eroded granite area located in Changting County

Fujian Province. There were two kinds of management measures: whole hill side coverage with Bahiagrass(WHCB) and the mixed forests of multitree species(MFMTS). The research also set two check measures: severely eroded region without restoration measures (CK1) and geomantic forest (CK2). The effects of ecological restoration were discussed in the aspects of biomass and productivity. Results showed that the averaged biomasses of WHCB and MFMTS were 23.03 and 23.13 kg

respectively

which were significantly higher than those of CK1(6.02kg) and significantly lower than those of CK2 (582.87kg). The productivity 〔5.30 t/(hm2·a)〕and restoration degree (RD) of productivity (0.40) of WHCB were low

so its biomass was also low (28.26 t/hm2) and RD of biomass was 0.11. The productivity 〔9.19 t/(hm2·a)〕and RD of productivity (0.78) of MFMTS were higher. Its biomass was (39.88 t/hm2) and RD of biomass was 0.17. The difference in RD showed the different effects of WHCB and MFMTS.
