摘要:
东北平原西部地区为草甸草原—草原过渡带，属典型的农牧交错区，生态环境脆弱，环境变化反映敏感。近百年来，本区的生态环境遭到严重破坏，大面积出现草原退化、沙化和盐碱化。通过对造成这一现象的自然和人文因素分析，结果表明，近百年尤其是近50年来，人口的大量增长和对水、土、生物资源的不合理利用，与其所处的地理环境及气候的变化（气温升高和降水波动较大等），二者达成了"共振"，导致了荒漠化的迅速发展，生态环境退化趋势显著。
Abstract:
The west of Northeast plain in China is a typical interlocking area between farming and stockbreeding, whose eco-environment is very fragile and vulnerable to environment change.During the last 100 years, regional eco-environment has suffered serious damages and former luxuriant grassland has changed into large-scale sandy, saline and degraded land.By analysis of the natural and human factors contributed to this phenomenon, a conclusion can be obtained that the serious results of rapid developing desertification and obvious degradation of eco-environment were caused by co-influence of rapid increasing populations, irrational utilization of natural resources and geographic environmental and climatic change(temperature rising and rainfall’s irregular variation and so on).
