摘要
This study investigated the insect community diversity in coniferous mixed forest,leguminous mixed forest,native species mixed forest and pine forest of subtropical hilly land in Heshan,Guangdong Province.The results showed that the richness index(S),diversity index(H’),probability of interspecific encounter(PIE)and evenness index(J’)of insect communities in four artificial forests of Heshan hilly land were relative higher.The result reflected that the structures of insect communities in these forests were complex,relatively stable and the plants in this ecosystem were diverse.These results also demonstrated that the degraded ecosystem in this region had been restored to some extent.The indexes of insect communities in four forest forms were significantly different.The insect communities in leguminous broad-leaved mixed forest and native species mixed forest were more complicated and sable than that of pine forest and coniferous mixed forest.Therefore,leguminous broad-leaved mixed forest and native species mixed forest are much better than pine forest and coniferous mixed forest for restoration of low subtropical degraded ecosystem in Heshan.
This study investigated the insect community diversity in coniferous mixed forest, leguminous mixed forest, native species mixed forest and pine forest of subtropical hilly land in Heshan, Guangdong Province. The results showed that the richness index （S）, diversity index （H＇）, probability of interspecific encounter （PIE） and evenness index （J＇） of insect communities in four artificial forests of Heshan hilly land were relative higher. The result reflected that the structures of insect communities in these forests were complex, relatively stable and the plants in this ecosystem were diverse. These results also demonstrated that the degraded ecosystem in this region had been restored to some extent. The indexes of insect communities in four forest forms were significantly different. The insect communities in leguminous broad-leaved mixed forest and native species mixed forest were more complicated and sable than that of pine forest and coniferous mixed forest. Therefore, leguminous broad-lea~,ed mixed forest and native species mixed forest are much better than pine forest and coniferous mixed forest for restoration of low subtropical degraded ecosystem in Heshan.
