摘要:
对陕西省吴起县已退耕还林10年的7种退耕还林地的物种多样性、生物量及其枯落物进行了系统的调查研究，旨在探明不同退耕还林地类型的恢复情况和效果，为今后退耕还林工作中树种选择及合理配置提供理论依据。结果表明：吴起县退耕还林10年后林下植被已趋于稳定；沙棘×山杏混交林是吴起县相对最为适合的混交林，有效的形成林草复合体系；不同退耕还林地群落的生物量具有明显的差异，其中沙棘×山杏混交林的林下草本层生物量最高；除油松和山杏纯林的枯落物生物量较小外，其他林地的枯落物生物量均大于天然草地。
Abstract:
A systematic study was carried out in different types of lands with conversions of croplands to forestlands from species diversity, biomass and litter in Wuqi County of Shaanxi Province, aiming at discussing the restoration situation and effect of different types of lands. The results show that conversion of cropland to forest project promotes positive vegetation succession for 10 years. Hippophae rhamnoides subsp. sinensis×Armeniaca sibirica mixed forests is relatively suitable forest in Wuqi County, forming the combining system of forest and grass effectively. Community biomass of different restored lands has significant difference. And herbaceous biomass of Hippophae rhamnoides subsp. sinensis×Armeniaca sibirica mixed forests is the greatest. Except that Pinus tabulaeformis and Armeniaca sibirica pure forest have smaller litter biomass, litter biomass of other woodland is greater than the natural grassland. The conclusion will provide a theoretical basis for the reasonable selection and allocation of tree species in the project of returning cropland to forestland in the future.
