soluble rock
例句与用法
- Carbonate rock is widely distributed in china both in depth and in area . a large number of tunnels are excavated and built in it . carbonate rock is distinguished from the other fracture rock in that most of it has bored hydro - chemical and hydraulic erosion in groundwater environment
我国境内碳酸岩层分布纵深横广，大量的隧道及地下工程修建于可溶岩中，而可溶岩和一般岩体的本质区别在于其受过地下水物理、化学环境的改造。 - So these karst series problems are lowness ability of making soils , distributing odds of surface water and groundwater , leakiness of fountain , alkalescence of circumstance , lowness of bio - diversity , rapidness converse succession of vegetation and fragility of soil character and entironment . and karst region produces many problems , e . g . rock desert , soil erosion and degeneration because of artificial influence and destruction
岩溶空间介质具有地上地下双层结构，可溶岩造壤能力低，岩溶水空间分布不均、地表地下水关系密切、水源易漏失，偏碱性环境、生物资源集聚程度低，植被逆向演替快、顺向演替难，岩溶地质与生态环境十分脆弱，受到人为因素的影响和破坏，极易产生石漠化、土壤侵蚀与退化等一系列问题。 - The results shows that the community richness , species diversity indices and evenness of tree layer and shrub layer share the same order , of which is higher in pure limestone region than that of in pure dolomite region , but it reverse in herb layer ; the coefficient of similarity is considerably low between all plots , while species turnover rate is quite high among the plots and is higher in dolomite region than that of in limestone ; in different karst regions , karst processing leads to niches diversity characterized by special morphologies and special element geochamical features , and therefore affect the dynamic and features of plant communities
我们在最有代表性之一的贵州茂兰喀斯特森林保护区选取纯灰岩和纯白云岩两种岩性的喀斯特环境，对其元素地球化学特征及其中原生性植物群落的相异性和物种多样性进行了对比，结果发现：不同岩性区域多样性：乔木层和灌木层为纯灰岩区纯白云岩区，草本层为纯白云岩区纯灰岩区，总体上纯灰岩区的高于纯白云岩区的；各样地间的相似性系数都很低，相同岩性类型内的明显高于不同岩性类型之间的相似度；物种周转率高，且白云岩区高于石灰岩区，种类组成差异明显；喀斯特区可溶岩地球化学背景通过喀斯特作用导致特殊的地形条件与元素地球化学特征，并引起局部小生境的分异从而影响植物群落特征。 - Water invasion bursten out during the railway - tunnel construction is usually the mainly problem in constructing or operating , also which brings surface water to exhaustion and pollutes environment or effects ecology , etc . the geleshan tunnel which crosses through guan - yin gorge anticline which trend is near south north , is located between tuanjie village and jingkou village of the shapingba zone , chongqing city , which is belongs to the inducting segment of yu - huai railway . the guan - yin gorge anticline appears to ridge and slot interlacing in land form , and is composed of clastic rock and carbonate rock from jurassic xintiangou group to triassic
歌乐山隧道位于渝怀线引入段重庆市沙坪坝区团结村至井口村之间，隧道穿越近南北向的观音峡背斜，地貌上表现为脊、槽相间，观音峡背斜由侏罗系新田沟组至三叠系下统碎屑岩和碳酸盐岩组成，歌乐山顶大部分出露可溶岩地层，地表岩溶发育，有大量泉水和暗河出口，并修建有多个中小型水库、大量池塘和水井。
