摘要: 以未种植巨菌草的荒山坡地为对照(CK),研究种植年限为1、2、3年的巨菌草群落的植物和昆虫多样性.结果表明: 种植巨菌草的植物群落物种丰富度比CK低,但盖度比CK高,种植3年的盖度最高为91.6%,比CK高75.8%;种植3、2、1年的巨菌草群落昆虫物种丰富度分别为CK的5.6、5.3和3.6倍;不同种植年限巨菌草群落植物和昆虫的Simpson、Shannon、均匀度、Brillouin、McIntosh等指数均显著高于CK,说明种植巨菌草可明显影响群落的植物和昆虫多样性;群落的植物和昆虫多样性随种植年限的增长逐渐趋于稳定.

Abstract: This paper studied the effects of 1-, 2- and 3 years of planting Pennisetum sp. on the plant and insect diversity in the Pennisetum sp. communities, taking the barren mountain land without planting Pennisetum sp. as the control (CK). Compared with CK, the plant species richness in Pennisetum sp. communities with different years of planting was lower, but the coverage was higher. The coverage in the Pennisetum sp. community having been planted for 3 years was the highest, up to 91.6%, and 75.8% higher than the CK. The insect species richness in the Pennisetum sp. communities having been planted for 1, 2 and 3 years was 3.6, 5.3 and 5.6 times of  the CK, respectively. The plant and insect diversity indices, including Simpson index, Shannon index, evenness, Brillouin index, and McIntosh index for the Pennisetum sp. communities with different years of planting were significantly higher than the CK, which indicated that the growth of Pennisetum sp. could affect the plant and insect diversity. With the increasing year of planting, the plant and insect diversity in Pennisetum sp. communities tended to be stable.
