上海宝钢生态园林植物群落类型及丰富度 - Kernel density estimation of species abundance distribution in rare and endangered castanopsis kawakamii natural forest
格氏栲天然林物种多度分布的核估计研究 - The area in question has great conservation value as following aspects : the population of butterfly shows great species abundance ; the heterogeneity of habitat revealed by the presence of multi - subspecies and multi - morphological species provides animals a steady habitat ; the faunal character and vertical distribution of butterflies show great value of ecological study ; the mid - mountain 8002600 ? m that has better environmental condition and less human disturbance is a typical
秦岭对东洋种的阻隔作用大于对古北种的作用。中山地带8002600m即暖温带落叶阔叶林和中山针阔叶混交林带环境状况良好，气候条件优越，受人为干扰少，因而物种丰富多样性较大。研究地区具有很高的保护价值。 - The following contents were mainly studied : ( 1 ) aspect , structure as well as characteristic of species composition between fragmental evergreen broadleaved forests and continuous evergreen broadleaved forest ; ( 2 ) species diversity , species abundance and species evenness between fragmental evergreen broadleaved forests and contin . . us evergreen broadleaved forest ; ( 3 ) plant floristic compositions at family and genus levels between fragmental evergreen broadleaved forests and continuous evergreen broadleaved forest ; ( 4 ) life form between fragmental evergreen broadleaved forests and continuous evergreen broadleaved forest ; ( 5 ) microclimate factor ( sun radiation , temperature , wind velocity , humidity ) in different level pattern ( open , edge and interior ) between fragmental evergreen broadleaved forests and continuous evergreen broadleaved forest ; ( 6 ) the relations between environment and soil factors as well as species diversity of forest community between fragmental evergreen broadleaved forests and continuous evergreen broadleaved forest
