环境变异 meaning in English
environmental alteration
environmental modification
environmental variation
Examples
- Environmental changes due to factors such as climate change are likely to be difficult to identify against the background noise arising from the numerous sources , both natural and man - made , of environmental variability
在众多自然及人为因素产生的环境变异源导致的噪音背景下，因气候变化等因素造成的环境变化很难确定。 - Karst areas have a most typical frail ecological environment and complex human - land system . its frailty is displayed in such distinct features as the strong sense of environmental mutation , low environmental capacity , limited ability of standing disasters , poor stability , sharp ecological competition and small quantity of living things
喀斯特地区具有一类最典型的脆弱生态环境和复杂的人地系统，其脆弱性表现出环境变异敏感度高、环境容量低、承灾能力低、稳定性差、生态系统竞争程度高、生物量小等鲜明特征。 - To make it , the only method is that we put up a long term monitoring system about cave and learn about the number and rate of entering of human being . after observing and analyzing the data , we can discover the regulation and the " entropy " which leads to the variation of environment . the management and protection of karst caves for tourism is a long - term and meticulous work , which entails a great deal of data - collection as well as research and needs the closely joint effort of the explorers , tourists and scientists studying these caves
要做到这一点唯一的办法就是对洞穴环境进行长期的监测，结合旅客的进洞人数和频率，进行动态观测，然后对这些观测资料进行分析对比，找出规律性的东西，找出环境变异的“嫡”值信息系统是一个集成的系统，其目的是对组织的业务数据进行采集、处理和交换，以支持和改善组织的日常业务运作，满足管理人员解决问题和制定决策的各种信息要求。 - The first geologic reason for degeneration of the eco - environment in the headwater area of the yellow river is that the increase of the recent geologic function caused desertification and grasslands resource decreased and underside changed , destroied the balance of water - air - heat in the area ; the second is that the water environment changes by the degradation and atrophy of frozen earth cause multilayer and synthesis cause of formation degeneration of the eco - environment ; the third is that the man and rats function accelerated degeneration of the eco - environment in the headwater area of the yellow river
摘要黄河源区生态环境恶化的地质原因之一是现代地质作用增强，形成以荒漠化为主的草地资源退化与下垫面改变，地区水气热平衡破坏；二是因冻土退化、萎缩，引起水环境变异，导致多层面与综合成因的生态环境恶化；三是人为及鼠类活动对源区生态环境恶化起著推波助澜的作用。 - It sets up a evaluated system by analyzing groundwater chemical components , through studying pertinence in water chemical component and soil strength , it also puts forward that water chemical change can map soil strength variation under water - soil interaction . from the theory of the water - soil interaction on , the interrelation of city construction , the variation of groundwater condition and the soil structure strength is analyzed and that the measure of soil structure and the significance which is by the water - soil interaction is studied in this paper . at the same time , in the paper : the recourse of the soil structure strength is summarized ; the physical meaning of soil mini - scale structure is defined ; the measure of soil structure is classified ; the four basis forms of the water - soil interaction is induced ; the chemistry mechanism of the water - soil interaction is discussed
通过水化学组份与土强度间的相关性分析，提出水化学组份的变异可以映射水土作用下土强度的变异；从水土作用的理论出发，分析了域市建设、地下水环境变异与土结构强度间的相互关系，研究了土的结构尺度及其在水土作用中的意义：总结了土的结构强度的来源、定义了土细观结构的物理涵义井划分了土的结构尺度及层次、归纳了水土作用的四个基本形式、讨论了水土作用的化学作用机理。
