A Tentative Analysis on Monitoring Results of Eco-recovery Project in Yijinhuoluo Banner of Inner Mongolia

摘要

Eco-recovery is one of the main measures for vegetation recovery, soil loss reduction and ecological environment improvement. The observation results of eco-recovery project in Yijinhuoluo Banner show that ① eco-recovery plays more important role in improving small scale climate. The average strong wind days and dust storm days were reduced by 39.9% and 57.1% than the averaged data of the Whole Banner during the monitoring period. ② the growth of arbor tree, shrubs and natural grass was increased by 30.0%, 22.0% and 81.0% than that in the contrast zone. ③ the average runoff modulus and sediment modulus is respectively 17,260m3/km2 and 1,135t/km2 that is reduced by 33% and 41% than the annual averaged in the monitoring station controlled area. ④ the eco-recovery promoted land-use structure and rural industrial structure readjustment, enlarged the vegetation area and increased the output value of forestry and animal husbandry.
