Conservation of Desert Non-commercial Forests in Northwest China of Xinjiang is an important and effective way of restoring vegetation and rapid formation of stable community. Being closed the forests is desired for these activities, but tending them can be hampered by lack of community characteristics. We initiated situ experiments in eight serious desertification and soil erosion plots to better unravel community characteristics. We found that variations in characteristics of forest communities studied. The plots are sorted into: Group one: Poplus euphratica and Poplus pruinosa dominated species (Plot and Plot.), Group two: dominated species is Tamarix elongata(Plot. and Plot., Haloxylon ammodendron dominated in Plot., Plot. and Plot. as Group three and when Poplus euphratica and Salix psammophila are as dominated ones of Plot. served to Group four. Polynomial model can be used to predict the relationships between Shannon-Wiener Indices and Simpson Diversity Indices, Shannon-Wiener Indices and Monk Richness Indices and Shannon-Wiener Indices and Simpson Dominance Indices. It is power model that can be used to describe the relationship between Shannon -Wiener Indices and MaIntosh Evenness Indices. All the findings are useful for restoring vegetation in Northwest China.
