| 4. | As a result of its high capability in interception of precipitation and enhanced evaporation of soil surface , the development of microbiotic crusts will more and more threaten the soil water condition which the artificial sand - fixing vegetation should rely on
在1956年固沙区，原来的花棒+柠条+油蒿为主的人工系统向油蒿+雾冰藜+小画眉草+隐花植物为主的半人工半天然系统的演变。 |
| 5. | Using the non - contact infrared ray temperature measurer and an index of temperature effect proposed by ourselves , the effects of artemisia ordosica and caragana intermedia on temperature at soil surface around individual plant are studied and compared with each other . comparison of temperature at soil surface showed that caragana intermedia has more obvious effect on soil surface temperature than that of artemisia ordosica
以鄂尔多斯高原典型植物油蒿和柠条作为研究对象，采用先进的非接触红外测温法，并提出度量植株温度效应的影响指数，对鄂尔多斯高原两种典型植物植株附近地表温度进行了比较分析，结果表明，柠条对地表温度的影响较油蒿明显。 |
| 6. | 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
通过对沙坡头人工固沙植被区主要建植种群柠条( caraganakorshinskii ) 、花棒( hedysarumscoparium )和油蒿( artemisiaordosica )的繁殖特性及种群结构的研究，以及自然侵入的一年生草本植物小画眉草( eragrostispoaeoides )和雾冰藜( bassiadasyphylla )繁殖特性的研究，探讨了在植被的持久性和变异性，分析评价了主要受恶劣环境压力下的人工固沙区植被的稳定性。 |
| 7. | 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
沙坡头人工固沙区植被随时间推进，老固沙区中的柠条种群将在50年或稍长的时间内消失，形成以油蒿种群为主，花棒种群为辅的多年生群落。 |
| 8. | The species were separately caragana korshinskii hydysarum scoparim artemisia ordosica in shrubs layer , eragrostis poaeoides bassia dasyphylla in herbs layer , bryum argenteum barbula ditrichodies in microbiotic crusts layer . and the dominant species of them were artemisia ordosica eragrostis poaeoides bryum argenteum respectively . due to the different time and the topographical varieties in the fixing - sand region , the horizontal structure of artificial vegetation manifested out the mosaic characteristics
灌木片层的主要植物种是柠条( caraganakorshinskii ) 、花棒( hydysarumscoparim ) 、油蒿( artemisiaordosica )等灌木植物，其中优势种为油蒿；草本片层的主要植物种有小画眉草( eragrostispoaeoides ) 、雾冰藜( bassiadasyphylla )等，其中优势种是小画眉草；生物结皮由藻类和苔鲜类构成，其中，银叶真鲜( bryumargenteum夕为固沙植被区鲜类地被层优势成分。 |
