| 1. | Changes of soil substrates in artemisia ordosica succession series 油蒿演替系列土壤基质的演变 |
| 2. | Study on allelopathic effects of essential oil from artemisia ordosica 油蒿挥发油的化感作用研究 |
| 3. | A study on soil animal dominant group - cleopteran in neimongol stipa grandis steppe 内蒙古库布齐沙带东段油蒿固定沙丘土壤微生物数量的垂直分布研究 |
| 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。 |
