corn and dry measure-
Main results are generalized as follows : in dry year, coupling fitness of water requirement to rainfall reaches 90 % for sorghum and spring millet during crop ' s growth and reproductive season in shunyi county, while 85 % for peanut and soybean, 70 % for spring com and cotton, 65 % for alfalfa, and 55 % for cropping pattern of rice followed by wheat
主要結論包括: 1 )順義區乾旱年型下,高粱和春谷全生育期需水與降水的耦合度達到90 ;花生和春大豆其次,達到85 ;春玉米和棉花為70 ;苜蓿65 ;水稻和冬小麥?夏作物組合耦合度只有55 。需水量和灌溉定額則與耦合度大小相反。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

本文對乾熱河谷形成的地理和氣候原因進行了闡述,並通過引證大量文獻,分析了乾熱河谷植被的歷史情況和現狀。Since the environmental situation in valley influenced directly the water body of river, the soil erosion control and re - vegetation in dhv is the most urgent task in the process of environmental harness along the rivers
由於乾熱河谷的植被情況直接影響河流水體的質量,因此河谷內的植被恢復和水土保持就成為流域治理的最重要的任務。分享友人
