摘要:

植被恢复是当前国内外研究的热点问题,通过对内蒙古伊金霍洛旗近15年来的植被恢复状况进行研究,基于当地自然环境特点构建评价指标体系,对伊金霍洛旗植被恢复的生态效益中水源涵养效益,土壤状况,环境净化效益进行了分析,总结植被恢复的整体生态效益。结果表明,目前全旗森林覆盖率达36.35%,植被覆盖率达到88%,在植被恢复土地0~30cm中,土壤孔隙度增大,养分含量增高,容重减小。伊金霍洛旗整体生态价值效益可达19.4亿元/a,比植被恢复之前增加297%。

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
