摘要
荒漠化作为一个环境问题，在人为过度经济活动的干扰和脆弱自然因素影响下（如疏松的地面组成物质，气候的连续干旱多风或暴雨等），正在继续蔓延，其影响的范围日益加大，因而监测其发展趋势，掌握其动态变化的规律乃成为当前各国荒漠化研究的一项重要内容。作者等选择我国在生态上较脆弱、气候上较敏感的河北省北部丰宁县及内蒙东南的多伦等地进行沙质荒漠化发展趋势的研究，经过野外调查监测和室内大量资料的对比分析，认为我国北方农牧交错地区的土地荒漠化虽然在局部地区进行治理后已开始逆转，但总的趋势仍在继续发展。因此，荒漠化作为一个环境问题应引起各方面的重视，及时采取各种措施积极进行治理。
Desertification as a global environment issue is continuously expanding due to unduehuman economical activities and the influences of natural factors such as loose surface material,dryclimate and frequent wind etc, For this reason, the monitoring of desertification development trend andits dynamical variations has become an important content of desertification research in manycountries. The author et al. selected the Fengning in Hebei Province and Duolun in Inner Mongolia toconduct the study on the development trend of sandy desertifieation, From field investigation,monitoring and comparative analysis of relevant data it may be concluded that the sandy desertificationin the interlaced agropastoral region of northern china,as a whole,is continuously expanding althoughin local places it exhibited a revese development trend.Therefore,great attention should be paid to theenviroment problem and measures have to be adopted to combat desertification.
