随着社会经济、科学技术的发展,人类为了最大限度地追求经济效益,不合理地开发和利用土地资源是造成水土流失的发生和发展的根本原因,直接制约受害地区经济的可持续发展。本文以甘肃东部地区水土流失为例,以相关的水土流失数据为依据,从水土流失的成因入手,思考如何有效地预防水土流失的发生,分析水土流失所带来的危害,并及时提出科学的应对措施,针对以往土地利用规划与水土保持规划各自为政的弊端,应当着眼于土地合理利用与水土保持措施的有机结合,进行科学的预防和治理,来实现水土流失地区的土地资源可持续利用和人地关系的协调发展。
With the development of society, economy and science and technology, in order to maximize the economic benefits, human beings, irrationally exploiting and using land resources, are the root causes of the occurrence and development of soil and water loss and directly restrict the sustainable development of the economy in the affected areas.
