摘要
国家林业局于1996年始在全国范围内组织了国家重点保护野生植物资源调查,历时5年,被调查的野生植物物种共191种(含变种)。调查表明,盐桦(Betulahalophila)、金平桦(Betulajinpingensis)、秤锤树(Sinojachiaxylocarpa)3树种此次调查未找到。原产地野生仅存1～10株的木本植物有12种:普陀鹅耳枥(Carpinusputoensis)、绒毛皂荚(Gleditsiajaponicavar.velutina)、丹霞梧桐(Firmianadanxiaensis)、广西火桐(Erythropsiskwangsiensis)、百山祖冷杉(Abiesbeshanzuensis)、羊角槭(Aceryangjuechi)、云南蓝果树(Nyssayunnanensis)、猪血木(Euryodendronexcelsum)、天目铁木(Ostryarehderiana)、华盖木(Manglietiastrumsinicum)、滇桐(Craigiayunnanensis)、膝柄木(Bhesasinensis)。原产地野生仅存11～100株的木本植物有9种:峨眉拟单性木兰(Parakmeriaomeiensis)、天台鹅耳枥(Carpinustientaiensis)、景东翅子树(Pterospermumkingtungense)、巧家五针松(Pinussquamata)、紫檀(Pterocarpusindicus)、梓叶槭(Acercatalpifolium)、异形玉叶金花(Mussaendaanomala)、广西青梅(Vaticaguangxiensis)、毛枝五针松(Pinuswangii)。仅存50000株以下的国家重点保护的野生植物共有85种,占191种的44.5%,形势异常严峻。
It has been carried out to research wild plants under the state emphasis protection since 1996.Until now,five years has been past. There are 191 wild plants surveyed. The result shows that 3 species had not been found. They are Betula halophila, Betula jinpingensis and Sinojachia xylocarpa.There are 12 species (include varieties)the remains less than 10 trees: Carpinus putoensis, Gleditsia japonica var.velutina,Firmiana danxiaensis,Erythropsis kwangsiensis, Abies beshanzuensis, Acer yangjuechi,Nyssa yunnanensis,Euryodendron excelsum, Ostrya rehderiana, Manglietiastrum sinicum, Craigia yunnanensis,Bhesa sinensis.There are 9 species the remains 11～100:Parakmeria omeiensis,Carpinus tientaiensis,Pterospermum kingtungense, Pinus squamata, Pterocarpus indicus, Acer catalpifolium, Mussaenda anomala,Vatica guangxiensis, Pinus wangii.There are 85 species (include varieties)the remains less than 50,000 on the field,i.e. 44.5% of 191 species.So the situation is very serious.It is discussed by the report that the differences of distribution in different regions and sites as well as the existing problems.Five proposals are also put forward.
