Relationships between veresk rangeland vegetation and environmental characteristic using multivariate analysis methods

摘要：

Interest in how various landscape components affect biotic and abiotic resources has grown over the past 2-3 decades (Brosofske et al,2001).The distribution and abundance of range species has been correlated with a variety of complex environmental gradients.Environmental factors affect range plant growth and need to be understood and considered by rangeland managers.Plant growth and development are controlled by internal regulators, which are modified according to environmental conditions (Manske 1997).Of the most ecologically important environmental factors affecting rangeland plant growth and distribution are topography (slope, aspect, and elevation) and soil properties (Jafari et al,2004).Environmental factor effects on vegetation could be considered as a main ecological subject during last recent decades.
