“…Our study has some limitations. Above all, it is clear that edaphic variables were not the only factors associated with the distribution of species in the study area, although they were usually the most important (Monier and Wafaa, 2003;Jafari et al, 2004). In addition, our study only examined one scale.…”

“…The relationship between vegetation and environment has been a subject of many ecological studies in history (ter Braak, 1987;El-Ghareeb and Shabana, 1990;Dargie and El-Demerdash, 1991;McDonald et al, 1996;Abbadi and El-Sheikh, 2002;Vogiatzakis et al, 2003;Jafari et al, 2004), and understanding the different ecological processes among stratal layers has long been recognized as a key issue in plant community ecology. Most of these studies have either focused on facilitative and competitive interactions between woody and herbaceous plants (Pugnaire et al, 1996;Pugnaire and Lazaro, 2000;Holzapfel and Mahall, 1999;Maestre et al, 2003), or on feedbacks in the dynamics of plant communities.…”

“…Among different environmental factors, soil is normally of great importance in plant growth, and is a function of climate, organisms, topography, parent material and time (Jafari et al, 2004). The relationships between vegetation and soil characteristics can be an important tool to assess sites, and the presence/absence of species can be used as bioindicators of soil conditions (Turner and Kelly, 1981;Wang, 1995).…”

Vertical structure in plant communities is well recognized, but questions remain about the response of different stratal layers in a plant community to resource use. This study provides a quantitative approach to compare the relationships of nine edaphic factors and species distributions in shrub and herb layers, respectively, in an arid valley of the upper Minjiang River, Sichuan Province, China. Classification (TWINSPAN) determined three groups of shrubs and four groups of herbs. Ordination (both DCA and DCCA) found a correlation among species and edaphic variables. Borcard's method [Borcard, D., Legendre, P., Drapeau, P., 1992. Partialling out the spatial component of ecological variation. Ecology 73, 1045-1055.] was employed to partition the variation of species abundance data into independent components: pure spatial, pure environmental, spatial component of environmental influence, and undetermined. Based on those four components, a quantitative comparison of ecological variation between shrubs and herbs further eluidated their different response to the environment. Although soil moisture (SM) content, pH, soil organic matter (OC) and available potassium (AK) were the most important factors to both, the explained ecological variation of herbs was lower than that of shrubs. Understanding differences between stratal layers in resource use can shed light on plant-environment relationships. r

“…This result is not in agreement with results from alpine steppe at 4000 m elevation in Qingzang-Tibet Plateau . The distribution of vegetation types is most strongly correlated with some soil characteristics suchas salinity, texture, potassium, lime and gypsum in Poshtkouh rangelands of Yazd Province in Iran (Jafari et al 2004). However, in the alpine meadow, soil texture controls the distribution of plant species by affecting moisture availability, aeration and distribution of plant roots.…”

Alpine meadow plays important roles in the animal production and conservation of water resources in the upper basin of Yellow River. In recent decades, desertification of this alpine meadow has resulted in changes in vegetation and soil features, as well as threatening the ecosystem functions and security. A field study was conducted to explain the response of vegetation pattern and soil features to desertification of alpine meadows. Results of vegetation studies indicated that hygrophytes were gradually replaced by mesophytes, xerophytes, and some annual psammophilous plants, and that cover and herbaceous biomass decreased along with the progressive desertification. Vegetation height increased in the slightly desertified stage, and then decreased in the very severe stage. Species diversity decreased, suggesting that desertification of alpine meadow contributedto species loss. This study also indicated that soil features gradually declined with increasing desertification of alpine meadow with A07027;
