川南长宁页岩气田动植物G-F多样性指数及保护措施

G-F diversity index and protection measures on animal and plants in the Changning shale-gas field,Southern Sichuan Basin

采用G-F多样性指数评价了长宁页岩气田动植物资源,结果表明:气田维管束植物有115科338属477种,F指数、G指数、G-F指数分别为69.021、5.651、0.918,G-F多样性指数从大到小依次为被子植物、蕨类植物、裸子植物;脊椎动物有59科113属142种,F指数、G指数、G-F指数分别为25.164、4.632、0.816,G-F多样性指数从大到小依次为鸟类、两栖类、爬行类、兽类。为保护长宁页岩气田动植物多样性资源,本文提出了相应保护措施建议。

Base on checklist of animal and plants in the Changning Shale-gas Field,D-G index(DG-F)was adopted to assess diversity of animal and plants.The results showed that the vascular plants belonged to 477 species,338 genera and 115 families;the F-index(DF),G-index(DG)and DG-F of vascular plants were 69.021,5.651 and 0.918 respectively,DG-F index decreased from angiosperm plants,pteridophyte plants to gymnosperm plants in sequence.The vertebrate belonged to 142species,113 genera and 59 families;the DF,DG and DG-F were 25.164,4.632 and 0.816 respectively,DG-F index decreased from avian,amphibia,and reptilia to mammalia in sequence.To protect animal and plants resources in the Changning Shale-gas Field,this paper presented related protection measures.
