The results of POPGENE analyze indicated that it was moderate level of the genetic diversity of Dipelta, mean PPB (percentage of polymorphic bands) h and I of 4 species of Dipelta as below: D.wenxianensis.(PPB=62.02%,h=0.1850,I=0.2826); D.yunnanensis (PPB=40.31%, h=0.1238, I=0.1874); D. floribunda (PPB=36.82%, h=0.1395,I=0.2045); D. elegans (PPB=15.51%, h=0.0583,I=0.0861). Genetic diversity in D.elegans is the lowest. It is possibly caused by the endemic distribution and local ecotope.
POPGENE分析结果表明,文县双盾木的多态位点百分率平均为62.02%,Nei&s基因多样性指数平均为0.1850,Shannon&s信息指数平均为0.2826;云南双盾木的PPB平均为40.31%;h值平均为0.1238;I值平均为0.1874;双盾木两个居群的PPB平均为36.82%;h值平均为0.1395;I值平均为0.2045;优美双盾木两个居群的PPB平均为15.51%,h值平均为0.0583;I值平均为0.0861;因此,我们认为双盾木属4个种的遗传多样性适中;而优美双盾木由于分布上的地理限制,居群的生境比较孤立,其遗传多样性较低。

Landuse planning data information is the important part of stateland resource and geographic spatial information resource. As the result of landuse planning information by the branch management is held in using only in the department, there is no uniform standard and criterion to complied,.It have not enough information communication and communion that should be make.So it has many forks in semantic definition. Many Landuse planning data information have the characteritic of complicated data structure, more kinds of storage formates and far-ranging distributing.
土地利用规划数据信息是国土资源和空间地理基础信息资源的重要组成部分,由于部门管理的土地利用规划信息基本上还是由行业内部所持有,许多还没有遵照统一的标准与规范,缺乏应有的沟通和信息流动,因此广泛地存在着语义上的分歧,具有数据结构复杂、存储格式多样、分布广泛的特点。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
