4 reaumuria soongorica and haloxylon ammodendron in desert - oasis ecotone show random distribution . the seedling of h . ammodendron shows clump distribution 4 、过渡带红砂和梭梭服从随机分布，梭梭幼苗表现为聚集分布。
In the paper i propose and realize the lod based on transitional band . quad tree algorithm and roam algorithm are depicted in detail 本文介绍了基于四叉树lod 、基于二元三角树结构的法则roam ，而且提出并实现了基于过渡带的lod 。
Intermediate zones of east - slope are in the way of oil travel and favorable territory oil moving to , so they are advantageous potential oil region 勘探层位以石炭系和二叠系为主。吉木萨尔凹陷斜坡过渡带也是较为有利的潜在含油区。
Geological condition in our country is far different from that in u . s . a . which decides the overall condition of cbm enrichment in china 我国与美国煤层气地质条件有很大的不同，美国是一个单一大陆的一部分，煤层气工业开采区位于过渡带。
Ordos plateau is a multi - layer and complicated ecological transition region , which exhibits complicated environmental and ecological characteristics 鄂尔多斯高原是一个多层次、复杂的生态地理过渡带，具有复杂多样的环境条件和生态特点。
Road restraint systems - part 4 : performance classes , impact test acceptance criteria and test methods for terminals and transitions of safety barriers ; german version env 1317 - 4 : 2001 道路限制系统.第4部分:安全屏障终端和过渡带的性能等
So we increase plant cover by 7 percent in every grid ( making transitional field changed from desert into oasis ) to study the impact of lulc variation on regional climate 因此我们在每个网格点上增加了七个百分点植被(使原来过渡带地区的沙漠变为绿洲) ，来研究植被变化所引起的气候响应。
The most of highway in our country have this matter because of differential settlement . the way in common use is set up a section between bridge abutment and embankment 对这个问题目前常用的解决方法是在桥台和路堤之间设置一桥头过渡带，使得桥台和路堤的工后沉降差能匀摊在这一过渡带内。
The system is appropriate for a province like anhui , which lies in the plain and low hill area of transition strip between warm temperate zone and subtropics zone , and where often occur drought disasters 所开发的系统适合于安徽省这样旱灾频繁发生的地区，其特征是位于暖温带与亚热带的过渡带的平原和丘陵。
5 the dynamic of soil water content and salinity is significantly different among communities in ecotone . the soil moisture and salinity are two main factors that influence the distribution and succession of plant communities 5 、过渡带各类型群落间土壤水盐动态存在显著差异，土壤水盐的梯度变化是群落分布和演替的根本原因。
