The reproductive characteristics and population structure of artemisia ordosica, hedysantm scoparium, caragana korshinskii and the reproductive characteristics of annual plants eragrostis poaeoides and bassia dasyphylla were observed in shapotou artificial revegetation area. stability of the artificial vegetation was appraised from the views of its persistence and variability under local natural condition. the study showed that : the artificial - natural vegetation built with sandbreaks and plants is stable in shapotou area
通過對沙坡頭人工固沙植被區主要建植種群檸條（ caraganakorshinskii ） 、花棒（ hedysarumscoparium ）和油蒿（ artemisiaordosica ）的繁殖特性及種群結構的研究，以及自然侵入的一年生草本植物小畫眉草（ eragrostispoaeoides ）和霧冰藜（ bassiadasyphylla ）繁殖特性的研究，探討了在植被的持久性和變異性，分析評價了主要受惡劣環境壓力下的人工固沙區植被的穩定性。The structures and dynamic changes of the artifical sand - fixing vegetation were studied based on the follow views : components of vegetation community, plant diversity, life - forms of vegetation, trends of plant growth, characteristics of the vertical and horizontal structure of vegetation, relationship between the vegetation community and environment ( including soil moisture temperature etc. ), relationship between the vegetation community and characteristics of plant physiological activities. some results were showed as follow : 1. components, diversity and life style of artificial vegetation in shapotou region the marked changes of artificial vegetation have taken place during more than 40 years, since the establishment of sand - fixing vegetation
本文以騰格里沙漠東南緣寧夏中衛縣沙坡頭地區人工固沙植被作為研究對象，採用傳統生態學的野外調查方法，從植被群落的組成、多樣性、生活型、群落生長動態、垂直結構特徵、水平結構特徵、群落結構與周圍環境（土壤含水量、溫度）相互關系及其與植物自身生理生態適應特徵關系等多個角度研究了人工植被群落的結構及其動態變化，取得了如下研究結果： 1 、植被群落組成、多樣性及生活型：沙坡頭地區人工植被經過近50年的演變，從流動沙丘到固定沙地，沙地植被的動態變化經歷了從人工植被到人工?自然植被的轉變，從人工植被建立初期的少數幾種引種植物到現有30多種植物，隨著固定沙地時間的延長，植物種類日趨豐富，並且人工植被在15 25年、 40 50年兩個階段，物種的周轉速率最大，即群落結構變化最大。Special seed germination and seedling survival mechanism in artemisia ordosica, eragrostis poaeoides and bassia dasyphylla ensured the maintenance and replacement of their populations in accordance with local environmental conditions. at o ld artificial vegetation of shapotou area, c. korshinskii is expected to disappear in the future of 50 years or so
沙坡頭人工固沙區植被隨時間推進，老固沙區中的檸條種群將在50年或稍長的時間內消失，形成以油蒿種群為主，花棒種群為輔的多年生群落。Changes of artificial vegetation growth in shapotou area
沙坡頭地區人工植被生長動態研究Water power plant at chaipingpu in sichuan province and huanghe shapotou in ningxia autonomous region
四川省紫坪鋪和寧夏自治區黃河沙坡頭的水利樞紐工程；The reproductive strategy of plants in shapotou played an essential role for vegetation stability. high resistance to drought and long life span enableed hedysarum scoparium and caragana korshinski to adapt themselves to the harsh environments
結果表明：在地處乾旱半乾旱的沙坡頭地區，通過機械固沙與植物固沙相結合的防風治沙模式，建立的雨育人工固沙區植被經過多年演替形成的人工?天然植被是穩定的。2. the structure of artificial vegetation in shapotou region the structure of vegetation usually consisted of a vertical structure and a horizontal structure of vegetation. based on the vertical structure of vegetation, there were three layers of artificial vegetation in shapotou region
2 、植被垂直結構及水平結構：沙坡頭地區人工固沙植被垂直結構可分為三個顯著的片層結構：灌木片層、草本片層和生物結皮片層。As a result, the water utility rate adds up to 0. 53, so the conclusion was drown that the water - saving reform project of shapotou irrigation area has great significance to weining regional economy development with technical feasibility, economic reasonableness and remarkable benefits
實施節水改造工程后的灌區灌溉水利用系數可提高到0 . 53 。從而得出：沙坡頭灌區節水改造工程技術上可行、經濟上合理，效益顯著，對寧夏衛寧地區的經濟發展具有重大意義With backward irrigation method, rough diversion operation used in agricultural irrigation brought about serious water wasting, moreover, most of irrigation works are outdated and without repair caused serious leakage, as a result, the water utility rate of irrigation is just 0. 38 in weining irrigation area of ningxia, so it is imperative to reform water - saving engineering
寧夏衛寧灌區灌溉方式落後，農業灌溉實行大引大排，浪費嚴重，且灌溉工程老化失修，滲漏嚴重，平均灌溉水利用率只有0 . 38 。因此，衛寧灌區實施節水改造勢在必行。實施節水改造后的衛寧灌區本文稱為沙坡頭灌區。分享友人
