| [natural vegetation restoration and soil nutrient dynamics of abandoned farmlands in forest-steppe zone on loess plateau]. | to understand the relationship between plant community succession and soil nutrient dynamics is crucial in intervening vegetation succession. this paper reported the results from a study carried out in a forest-steppe zone on the loess plateau, with emphasis on the vegetation characteristics and soil nutrient dynamics duringvegetation restoration on abandoned farmlands of this area. the results showed that under zonal habitat conditions, natural vegetation succession would turn toward the origin ... | 2005 | 16471333 |
| [niche characteristics of dominant populations of sophora davidii community in loess gully region]. | based on field investigation data and employing levin and niche proportional similarity formulae, this paper calculated the niche breadth, niche proportional similarity, and niche overlap of 13 dominant species of sophora davidii community in loess gully region. the results showed that the niche breadth of the dominant populations of sophora davidii community decreased in order of sophora davidii (0.964), artemisia giraldii (0.775), arteniisia gmelinii (0.664), thenmeda triandra var. japonica (0 ... | 2005 | 16515163 |
| [dynamics of plant community species diversity in the process of ecological rehabilitation in north shaanxi loess area]. | based on the vegetation survey on 18 sampling plots in wuqi county of shaanxi province, and by using the methods of substituting space series for time series and of contrastive analysis, the dynamics of plant community species diversity in the process of ecological rehabilitation in the county was analyzed from the aspects of succession time, rehabilitation mode, and slope direction. the results showed that in the 25 years natural succession series, the natural restoration community on previous ... | 2009 | 19459383 |
| germinable soil seed banks and the restoration potential of abandoned cropland on the chinese hilly-gullied loess plateau. | poor vegetation cover is generally considered to be a major factor causing soil erosion on the loess plateau in china. it has been argued that tree planting restoration is ineffective, and natural re-vegetation is an alternative ecological solution for restoring abandoned cropland and controlling soil erosion. the aims of this study were to investigate the characteristics of soil seed banks and to assess the natural restoration potential of abandoned cropland in the hilly-gullied loess plateau. ... | 2010 | 20694556 |
| [allelopathic effects of the humus soils from betula platyphylla and quercus liaotungensis pure plantations on 9 kinds of common shrubs and herbs]. | the humus soils were collected from betula platyphylla and quercus liaotungensis pure plantations and woodless land separately where the site conditions were basically the same, and taken as medium for potting culture test of 9 kinds of shrubs or herbs in plastic greenhouse to assess the allelopathic effects of humus soils of pure plantations on shrubs or herbs. humus soils from b. platyphylla plantation significantly inhibited the seed germinations of medicago sativa and melilotus officinalis, ... | 2014 | 25223017 |
| [characteristics of seed rain on abandoned slopes in the hilly-gullied loess plateau, northwest china]. | the objective of this study was to analyze the dynamic characteristics of seed rain on abandoned slopes in the hilly-gullied loess plateau region and identify the relationship between seed rain and standing vegetation. three abandoned slopes were chosen as sampling sites in zhifanggou watershed. thirty traps were installed at each site to collect seed rain from october 2010 to april 2013. standing vegetation was surveyed to identify dominant species in august 2011 and 2012, respectively. thirty- ... | 2015 | 26094452 |
