  grassland
The threshold wind velocity of a number of variables was studied in four different land-use types: farm land, forestland, wild grassland and a flood plain in the Yongding River sandy land in Beijing.
      
The following conclusions were drawn: 1) The order of decreasing threshold of wind speed for sand displacement and surface roughness were forestland, wild grassland, farm land, sparse wild grassland and flood plain.
      
3) The mechanical composition of sand particles consisted mainly of silver sand in the flood plain and sparse wild grassland, and of silver sand, particle silver sand and floury sand in other land-use types.
      
The whole study area was divided into the wetland zone, the ecotone and the arid grassland zone in terms of habitat characteristics and vegetation types.
      
The greatest evenness indices (E) were found in the arid grassland zones.

Experience in Studying Synanthropization in the Course of Pasture Digression in the Transural Steppes by the Transect Method
      
The process of steppe pasture digression resulting from grazing by different farm animals was studied by the transect method.
      
The results of long-term stationary research on the assessment of aboveground phytomass and soil moisture dynamics in a steppe pasture are presented.
      
This feature distinguishes it from the similar community of the near-Atlantic waters that is based on a pasture web, at least as far as the bivalve mass species are concerned.
      
In a linear transect, five sampling zones were established, from the centre of the camping area to the surrounding Nardus stricta-dominant pasture.

We concluded that the conversion project from croplands to forests and grasslands based on scientific principles is very important in the formation of carbon sinks for reducing greenhouse effects.
      
The relationship between species richness and productivity in four typical grasslands of northern China
      
In this paper, we examine the relationship between species richness and productivity in four typical grasslands of Northern China at different spatial scales.
      
For all classes of ecosystems, the proportion of underground phytomass averages 26.7% of the total amount, varying from 22.0% in forests to 57.1% in grasslands and brushwoods.
      
Other land-use/land-cover (LULC) classes have the following NPP densities (in areas covered with vegetation): grasslands and brushwoods, 278 g C/m2; forests, 224 g C/m2; and wetlands, 219 g C/m2per year.

  grass
The average annual biomass of fine roots in ryegrass was twice that of the mixed natural grass-forest land.
      
The total amount of natural grass roots was 4.4 times that of the ryegrass model.
      
The amounts of water-stable aggregates of natural grass-forest lands (TN model) were higher than those of managed grass-forest lands (TL model).
      
We conclude that the program of converting agricultural lands to forest-grass lands is an effective way in improving soil anti-erosion capability.
      
The 26 remaining spectral clusters were merged into six vegetation types using the Chinese vegetation taxonomy system: evergreen broad-leaved forest, coniferous forest, bamboo forest, shrub-grass, aquatic vegetation, and agricultural vegetation.
