Abstract
Grasslands desertization and desertification and soil and water loss is very serious in arid and semi-arid grasslands in China.For resolving this problem,we should do well in soil and water conservation and ecology monitoring in the first.In order to analyze and evaluate every soil and water conservation measure effects objectively,we dynamically monitored each ecological index for 4 years before and after implementing every measures in our test base,studied the impacts on soil moisture and soil nutrient and grasslands vegetation of enclosure and different recovering measures.Results indicate that the impact on soil moisture and soil nutrient and grasslands vegetation of enclosure is obvious,especially the impact on grasslands vegetation.Vegetation coverage degree increases 58.66% after enclosing.Different recovering measures in the enclosure also influence soil moisture and soil nutrient and grasslands vegetation distinctly.
