To control effectively non-point pollution of the Heihe basin and improve water quality of Heihe river basin
the basin was partitioned to nine zones based on basin district.The expert judgment model was adopted to estimate the soil erosion intensity
and the absorbed nitrogen and phosphorus estimating model were used to estimate absorbed nitrogen and phosphorus loads.Houzhenzi county
Chenhe county
Ganyuwan county and four village of Mazhao county are the key regions of non-point source pollution control.Returning farmland for forestry and pasture
decreasing tillage land
increasing vegetation cover ratio and rationally land use plan would be the effective measures of controlling absorbed nitrogen and phosphorus pollution
