摘要
在研究东北平原西部科尔沁沙地与松嫩沙地的分布与面积、类型与特征的基础上，在市场经济形势下，提出对轻度和潜在沙漠化土地，采用林、果（包括瓜）、药、杂（杂粮）综合治理与开发模式，取得了十分显著的经济效益、社会效益和生态效益。
Having studied the distribution, area, type and property of Horqin and Songnen sandy lands, the author put forward a development model for slight and potential desertifcation lands: ①to change single popolus forest form to construct coniferous and broad leaved mingled forest; ②to set up sandy orchard; ③to plant water melon suitable for growing in sandy land; ④ to introduce medical plants with high efficiency such as Borago officinalis L., Oenathera odorala, Astragalus mongholicus B., Silybum marianum (L)G. and Glyoyrrhiza uralensis F., etc.; ⑤to establish artificial grassland to highten the vegetation coverage of sandy land; ⑥to plant coarse cereals such as sun flower and mung bean cash crops. The practice of this model has obtained satisfactory economic effect, has improved the eco environment and has mobilized the enthusiasm of the local peasants to comprehensively desertification control and development.
