【摘要】：采用樣帶法對(duì)西雙版納納板河自然保護(hù)區(qū)自然林(熱帶雨林和常綠闊葉林)和橡膠林白蟻群落進(jìn)行了調(diào)查,探討了橡膠林種植對(duì)白蟻群落結(jié)構(gòu)、食性類(lèi)群組成和多樣性的影響。結(jié)果表明:(1)在3種森林類(lèi)型中,共收集白蟻樣本397份,隸屬于2科10屬20種,熱帶性白蟻種屬組成突出;(2)季節(jié)對(duì)白蟻群落多度和豐富度有顯著影響,總體表現(xiàn)為雨季高于旱季;(3)自然林中白蟻多度、豐富度和多樣性指數(shù)顯著高于單一橡膠林,且橡膠林中白蟻稀有種數(shù)量顯著減少,同時(shí)土木食性白蟻的數(shù)量比例顯著低于自然林,而木食性白蟻比例增加。研究認(rèn)為,熱帶地區(qū)大面積單一橡膠林種植可對(duì)"生態(tài)系統(tǒng)工程師"白蟻群落結(jié)構(gòu)和多樣性產(chǎn)生較大的負(fù)面影響,應(yīng)重視發(fā)展復(fù)合橡膠林模式保護(hù)白蟻生物多樣性。
[Abstract]:The natural forest (tropical rain forest and evergreen broad-leaved forest) and the termites community of rubber forest were investigated by transect method in Nabanhe Nature Reserve Xishuangbanna. The results showed that among the three forest types, 397 samples of termites were collected, belonging to 20 species belonging to 10 genera and 2 families. The season of tropical termites has significant influence on the abundance and richness of termites community, which is higher in rainy season than in dry season. The abundance and diversity index of termites in natural forest is significantly higher than that in single rubber forest. And the number of rare species of termites in rubber forests was significantly reduced, and the proportion of termites in civil engineering was significantly lower than that in natural forests, while the proportion of termites in wood was increased. The large area of single rubber plantation in tropical area can have a great negative impact on the structure and diversity of termites community of "ecosystem engineer", so we should pay attention to the development of compound rubber forest model to protect the biodiversity of termites.
