| 摘 要： | 荒漠化是人为强烈活动与脆弱生态环境相互作用的产物,是人地关系矛盾的结果,半个世纪以来,我国荒漠化发展的速度很快,已严重影响社会经济的可持续发展。本文应用地球动力学原理分析和研究人类活动对土地荒漠化的影响,建立了GIS技术支持下人为作用对荒漠化影响的通用数学模型,并以松嫩平原西南部为例进行了验证,计算结果与前人研究成果一致,表明所提的方法是可行的。

| Abstract: | Desertification is the result of interaction between human being and fragile eco-environment. It is also the consequence of the contradiction between human being and land. During the last half century, because the population increase rapidly, people excessively use the land resources, resulting the rapid expand of soil desertifieation , it deeply affected the sustainable development of the society and economy. Based on the theory of Geodynamies and GIS, A universal model of the impacts of human activities on the soil desertifieation is presented and applied to the southwestern of Songnen Plain. The results show that the method is practicable. |
