黄土高原生态退化与恢复

Advances in ecological degeneration and restoration of Loess Plateau

我国的黄土高原不仅是水土流失最为严重的地区,同时也是生态环境最脆弱的地区之一,严重地限制着该区域经济发展和人们生活水平的提高,因此,加大对黄土高原生态环境的恢复治理显得尤为重要。本文在详细分析黄土高原地形地貌、气候及土壤3个方面特殊性的基础上,综述了当前黄土高原退化现状以及造成其退化的原因,提出了生态恢复治理的综合措施,并对当前黄土高原生态恢复相关研究中所存在的问题提出了建议。

The Loess Plateau is the one of the most vulnerable areas of ecological environment,mainly characteried by serious soil erosion in China,which restrict the economic development of the region and the improvement of living standard.Therefore,it is very important to govern the ecological environment of Loess Plateau.This paper mainly analyzes and discusses three aspects of Loess Plateau,which include the particularity of geomorphology,topography,climate and soil.Simultaneously,we summarize the relevant measures of ecological restoration combining the current status of Loess Plateau deterioration and analyzing the reasons which result in the deterioration.Finally,we present some suggestions for the problems which mainly relate to the ecological restoration of Loess Plateau in recently relevant researches so as to provide some guidances for ecological environment comprehensive management of the Loess Plateau in future.
