Through the analyses of characteristics of gully thalweg and soil erosion in upland and gully land, sediment sources in small watershed, sediment yield relationship between upland and gully and ecological functions of vegetation corridor, it is considered that vegetation corridor combined with land preparation measures may block runoff and sediment from upland and reduce the amount of soil erosion in a watershed by 54. 5 % ~ 77. 0 %
摘要在分析黃土高原地區的溝沿線、溝沿線上下溝間地和溝谷地土壤侵蝕特徵、小流域泥沙來源、坡溝侵蝕產沙關系的基礎上,結合廊道的生態功能和以往的研究結果,認為在溝沿線的上部建立草灌與整地工程措施相結合的植物廊道,來攔蓄阻截溝間地的來水來沙,可使流域的土壤侵蝕量減少54 . 5 % ~ 77 . 0 % 。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
歌樂山隧道位於渝懷線引入段重慶市沙坪壩區團結村至井口村之間,隧道穿越近南北向的觀音峽背斜,地貌上表現為脊、槽相間,觀音峽背斜由侏羅系新田溝組至三疊系下統碎屑巖和碳酸鹽巖組成,歌樂山頂大部分出露可溶巖地層,地表巖溶發育,有大量泉水和暗河出口,並修建有多個中小型水庫、大量池塘和水井。Roadside gullies are generally cleared manually every two weeks. application of larvicidal oil is done on weekly basis as a precaution against mosquito breeding. dirt and refuse taken from gullies are delivered to refuse collection points
在本港的道路上,大部分排水溝渠的垃圾和沙泥是由本署清潔工人以人手清理,通常每2星期清理1次,每星期需加上滅蚊油,以防蚊蟲滋生。The paper puts forward the structure of debris - retaining works system, layout consideration and construction principle for the coarse sand concentrated coming area, time sequence of the works construction of " large - scale first and small - scale second ", " downstream first and upper stream second ", and " carrying out section by section " and some problems demanding prompt solution according to the present facts and ; to speed up the preparation of a large - scale debris - retaining reservoir ; to draft the standards for a large - scale debris - retaining reservoir as quick as possible and ; lay emphasis on the schedule of various projects and correct understanding and fully playing the function of key dams through the analysis on achievements and problems of debris - retaining works building and combining with the gully characteristics of coarse sand concentrated coming area
摘要通過對粗泥沙集中來源區攔沙工程建設成就與問題的分析,結合粗泥沙集中來源區溝道特徵,提出了粗泥沙集中來源區攔沙工程體系的構成、布局思路、建設原則,提出了「先大后小」 、 「先下後上」和「分段實施」的攔沙工程建設時序,並針對當前工作實際,提出了亟待解決的幾個問題:加快大型攔泥庫前期工作步伐、盡快制定大型攔泥庫標準、重視各類工程實施進度以及正確理解和執行規范、充分發揮骨幹壩的作用等。Abstract : because the shenfu - dongsheng mine area is located in intermediate of arid and semiarid zone, its ecological environment is very fragile. based on the fragileeco - environmental, the coal mining and construction have brought out some new environmental problems. man - made debris flow problems is the most serious of them which caused by coal mining, construction of railway and highway as wellas exploiting stone. through a great deal of experiments of artificial simulation setting water rushing to two types of slope debris flow and debris flow gully in shenfu - dongsheng mine site, the characteristics is favourable to formation of debris flow ; ( 2 ) the waste gangue is easy to initiate and is main solid material of debris flow in this area ; ( 3 ) the whole debris flow process could be observed through the model simulation experiment of debris flow gully. at present, this experiment method is the best way to analyze debris flow genesis and process
文摘:神府東勝礦區位於黃土高原北部乾旱半乾旱過度地帶,由於煤田的大量開采,誘發了大量的環境問題,尤以人為泥石流最為嚴重.本文以神府-東勝礦區人為泥石流為研究對象,採用人工放水沖刷模擬實驗的方法,分析了坡面型和溝谷型泥石流源地鬆散體起動、產沙、泥石流過程的特性,所得結論為: ( 1 )放水歷時長、強度大,有利於泥石流的形成; ( 2 )棄土石渣易起動,是該區泥石流固體物質的主體; ( 3 )溝道型泥石流放水沖刷模擬實驗,便於觀測泥石流的全過程,坡面型泥石流放水沖刷模擬實驗,利於統計產沙、觀測侵蝕形態Because the shenfu - dongsheng mine area is located in intermediate of arid and semiarid zone, its ecological environment is very fragile. based on the fragileeco - environmental, the coal mining and construction have brought out some new environmental problems. man - made debris flow problems is the most serious of them which caused by coal mining, construction of railway and highway as wellas exploiting stone. through a great deal of experiments of artificial simulation setting water rushing to two types of slope debris flow and debris flow gully in shenfu - dongsheng mine site, the characteristics is favourable to formation of debris flow ; ( 2 ) the waste gangue is easy to initiate and is main solid material of debris flow in this area ; ( 3 ) the whole debris flow process could be observed through the model simulation experiment of debris flow gully. at present, this experiment method is the best way to analyze debris flow genesis and process
