Abstract:

Vegetation restoration is the current research hot topic at home and abroad.This paper studies the nearly 15 years of vegetation restoration in Yijinhuoluo Banner.Based on constructing an evaluation index system for the local natural environment characteristics of vegetation restoration,the ecological benefits in Yijinhuoluo Banner,benefits of water conservation,soil condition,environment purification efficiency are analyzed and the overall ecological results of vegetation restoration summarized.The results show that the forest coverage rate of the whole Banner is 36.35% at present and the vegetation coverage rate is 88%.In the land of vegetation restoration at 0~30cm,the soil porosity increases,the nutrient content increases and the density decreases.The overall ecological value of Yijinhuoluo Banner could reach 1.94 billion yuan /a,an increase of 297% over that before vegetation restoration.

Key words: vegetation restoration, evaluation, ecological benefits, ecological value, Yijinhuoluo Banner, Inner Mongolia
