中文摘要 | 在新疆准噶尔盆地东南缘广泛分布的平缓低洼地、平缓沙地和半流动沙丘等不同生境类型的梭梭天然林内,进行人工接种肉苁蓉对梭梭天然林影响的试验研究。结果表明,接种肉苁蓉对梭梭天然林林下植被的种类组成、植株数量、植被盖度、物种多样性、生物量以及天然更新的幼苗幼树等都将产生不同程度的影响。其中,在平缓低洼地的梭梭天然林内,因挖接种穴和回填。林下植被的个体数损失4.1*10^4株·hm^-2,占接种前林下植被个体总数的18%;林下植被的生物量损失35.64kg·hm^-2.占接种前林下植被生物总量的14.9%;梭梭幼苗幼树的个体数损失1320株·hm^-2,占接种前梭梭幼苗幼树个体总数的24.2%。在平缓沙地的梭梭天然林内,林下植被的个体数损失2.6*10^4株·hm^-2,占接种前林下植被个体总数的49%;林下植被的生物量损失39.87kg·hm^-2,占接种前林下植被生物总量的19.0%;梭梭幼苗幼树损失345株·hm^-2,占接种前梭梭幼苗幼树的18.8%。在半流动沙丘的梭梭天然林内,林下植被的个体数损失2000株·hm^-2,占接种前林下植被个体总数的5%;林下植被的生物量损失9.98kg·hm^-2,占接种前林下植被生物总量的6.0%;梭梭幼苗幼树损失256株·hm^-2。占接种前梭梭幼苗幼树的3.8%。受挖接种穴和回填直接影响的调查样方内,植物个体数减少26%~53%。植被总盖度减少46%~52%,物种多样性下降5%~13%,生态优势度提高2%~6%,梭梭天然更新幼苗幼树减少40%~75%,林下植被地上和地下部分的生物量损失25.2%~55.7%。[著者文摘] |
英文摘要 | In this paper, the effects of Cistanche deserticola inoculation on the undergrowth vegetation of natural H. am-modendron forest were studied in low-lying land, slow and gentle desert, and semi-mobile dune, the three dif-ferent habitats of natural H. ammodendron forest at the eastern edge of Zhunger Basin in Xinjiang Au-tonomous Region, .The results showed that C. deserticola inoculation had different effects on the vegetation composition, plant number, vegetation coverage, species diversity, biomass, and naturally regenerated sapling under natural H. ammodendron forest. In the natural H. ammodendron forest in low-lying land, the amount of lost vegetation was 41 000 ind1 hm"2, accounting for 18% of total undergrowth vegetation before inocula-tion, the loss of biomass was 35. 64 kg- hm~2, accounting for 14. 9% of the total, and the amount of lost sapling was 1320 ind’ hm , accounting for 24. 2% of the total. In the natural H. ammodendron forest in slow and gentle desert, the loss of plant individuals under the forest was 26000 ind- hm" 2, accounting for 49 % of total amount of undergrowth vegetation before inoculation, the loss of biomass was 39. 87 kg- hm"2, ac-counting for 19.0% of the total, and the amount of lost sapling was 345 ind’hm ,accounting for 18.8% of the total. In the natural H. ammodendron forest in semi-mobile dune, the loss of plant individuals under the forest was 2000 ind1 hm"2, accounting for 5% of total number of plants before the inoculation, the loss of biomass was 9.98 kg- hm~2, accounting for 6. 0% of the total, and the amount of lost regenerated H. am-modendron sapling was 256 ind’hm"2, accounting for 3.8% of the total. In the survey quadrate directly influ-enced by inoculation, the number of plants was reduced by26%~53%, overall vegetation coverage reduced by 46 % 52 % , species diversity decreased by 5 % ~ 13 % , biological advantage increased by 2 % ~ 6 % , naturally regenerated H. ammodendron sapling reduced by 40% ~75%, and biomass loss of aerial and ground parts under the forest lost by 25.2 % ~ 55.7 % . |
