地理分布

After extensive survey of species of Takakia, we couldn't have found any individuals because of its limited population distribution, so we decided to add some relevant studies of conservation genetics to make up for the shortage of this project, including the analysis of effect of stand age and management regime on genetic diversity on Thuidium cymbifolium in Western China, and genetic structure of the endangered insular plant Neolitsea sericea on the Zhoushan archipelago. Results showed that the population of T.

藻苔类植物多分布于高山雪域地带，且范围极为有限，课题组经多次野外搜寻，未能采集到活体材料，而课题实施时间仅有1年，因此课题组同时积极开展云杉人工林林下大羽藓遗传多样性恢复的动态变化，以及岛屿地理隔离对濒危物种舟山新木姜子种群遗传结构的影响等研究，以弥补项目实施之不足。

According to the methodology and technology of SOTER at a scale of 1∶1 000 000,a digital spatial database and a simple attribute database at a scale of 1∶200 000 was established in the south of Jiangsu province by integrating relief map, geology map and soil map with Arc/info software.

现有的土壤与地形资料在区域地理与环境研究中是必不可少的，而这些资料经常不能被充分地利用，主要原因是其信息的表达方式很落后-它们常常是零散的、不全面的，并且经常缺乏资源分布的空间与时间序列的信息。

The lithofacies and paleogeography mapping based on high resolution sequence analysis show the sandbody distribution clearly. The paleoshoreline in this area is defined by paleosalinity recovery. Deltaic front subfacies mainly developed in the study area, with small-scale of deltaic plain in northeast.

基于高分辨率层序地层学分析的岩相古地理编图结果非常清晰地显示了研究区长6段砂体展布特征，同时通过古盐度恢复，首次确定了该区湖岸线的位置，从而确定研究区主要发育三角洲前缘亚相，三角洲平原只在东北一隅有小范围分布。

Based on paleogeography, paleotectonic condition, rock composition, structure and tectonics, as well as development and distribution feature of sand body, the authors believe that the sedimentary environment of Dalinghe reservoir is mainly gentle slope-type sublacustrine fan middle fan subphase with supplying waterway, which is composed of braided channel, braided interchannel, middle fan front microfacies.

根据古地理和古构造条件，以及岩石成分、结构、构造、砂体发育及分布特征，认为辽河坳陷欢2-14-16区块大凌河油层的沉积环境主要是具供给水道的缓坡型湖底扇中扇亚相，由辫状沟道、辫状沟道间、中扇前缘微相组成。

Supported by GIS, maps were overlapped of normalized vegetation index, topograph, soils, government districts, yearly rainfall, yearly mean temperature, accumulated temperature during growing period of wheat, so as that ecological layers for wheat were stratified objectively and a base graph of non wheat image cell was plotted for average year.

在地理信息系统支持下，将处理好的归一化植被指数图与地形图、土壤质地图、政区图、年降水量图、年平均气温图、小麦生育期积温图等背景图件叠加，进行比较客观的小麦遥感生态分层，并制成常年非麦象元分布底图。

An observer who is commoving with those points on the surface of deformable Earth which undergo a deformation will experience the material variation of Newtonian gravitational force field.

地球重力场的时空结构与分布特性无论在基础理论研究还是在地理空间信息建设中都具有重要意义。

Distributing means dividing data on the grounds of the needs of users and demarcating is putting different framework to varying places.

分片是按照需求将数据库进行分割，而分布是将不同的片段放置在不同的地理位置上。

This paper adopted relief map and TM, SAR image, impaling the image disposal technology of Remote Sensing and the space analysis technology of Geography Information System, and combining landscape ecology theory to analyze the effect of flooding before and after 1998 on soil salinization. The analysis includes several aspects such as quantity, spatial distribution and landscape distribution of salt and alkaline land in Zhenlai County.

本文采用地形图和SAR、TM影像，运用遥感图像处理技术、地理信息系统的空间分析技术，结合景观生态学理论，从盐碱地数量、空间分布和景观格局几个方面分析了1998年洪水前后镇赉县盐碱地景观的动态变化，进而揭示洪水对土壤盐渍化的影响机制。

Based on the reflection spectral characteristic of the land surface feature in Duolun area, by using multispectral satellite image data and adopting image processing of false color composite and ratio false color composite, with support of Geographic Information System, the space disbribution of the land desertification is interpreted and measured in this paper.

在内蒙古多伦县土地沙化现状的调查中，利用多波段卫星图象数据，根据多伦地区各类地物的波谱特征，采用了假彩色合成及比值假彩色合成等遥感图象处理方法，在地理信息系统技术的支持下，对多伦地区沙化土地的空间分布和面积进行了详细的解译和测算。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
