Study on the Para Position Allocation of Soil and Water Conservation Measures in Small Watershed of Gullyand Hilly Regions on Loess Plateau;

The vegetation building of the loess plateau should not only adhere to the laws of regional distribution of natural vegetation, but also fully consider the different laws of microclimate in different topography and location and persist in mutual para position allocation under the conditions of microclimate and plant species ecology.
